Sexual Orientation

Sexual Orientation
Sexual orientation refers to "an enduring pattern of emotional, romantic, and/or sexual attractions to men, women, or both sexes." According to the American Psychological Association, "it also refers to an individual’s sense of personal and social identity based on those attractions, behaviors expressing them, and membership in a community of others who share them." Sexual orientation is usually classified according to the sex or gender of the people who are found sexually attractive. Though people may use other labels, or none at all, sexual orientation is usually discussed in terms of three categories: heterosexual, homosexual, and bisexual. These orientations exist along a continuum that ranges from exclusive heterosexual to exclusive homosexual, including various forms of bisexuality in-between. Sexologists see this linear scale as an oversimplification of a more nuanced notion of sexual identity.
Most definitions of sexual orientation include a psychological component, such as the direction of an individual's erotic desire, or a behavioral component, which focuses on the sex of the individual's sexual partner/s. Some definitions include both components. Some people prefer simply to follow an individual's self-definition or identity.
Some scholars of sexology, anthropology and history have argued that social categories such as heterosexual and homosexual are not universal. Different societies may consider other criteria to be more significant than sex, including the respective age of the partners, whether partners assume an active or a passive sexual role, and their social status.
Sexual identity and sexual behavior are closely related to sexual orientation, but they are distinguished, with identity referring to an individual's conception of themselves, behavior referring to actual sexual acts performed by the individual, and orientation referring to "fantasies, attachments and longings." Individuals may or may not express their sexual orientation in their behaviors. People who have a homosexual sexual orientation that does not align with their sexual identity are sometimes referred to as closeted.
Sexual identity may also be used to describe a person's perception of his or her own sex, rather than sexual orientation. The term sexual preference has a similar meaning to sexual orientation, but is more commonly used outside of scientific circles by people who believe that sexual orientation is, in whole or part, a matter of choice.[citation needed]
Sexual orientation is a concept that evolved in the industrialized West and there is a controversy as to the universality of its application in other societies/ cultures. As Michel Foucault put it, "'Sexuality' is an invention of the modern state, the industrial revolution, and capitalism." Non-westernized concepts of male sexuality differ essentially from the way sexuality is seen and classified under the system of Sexual Orientation. The validity of the notion of 'sexual orientation' has also been questioned within the industrialized Western society.

The earliest writers on sexual orientation usually understood it to be intrinsically linked to the subject's own sex. For example, it was thought that a typical female-bodied person who is attracted to female-bodied persons would have masculine attributes, and vice versa. This understanding was shared by most of the significant theorists of sexual orientation from the mid nineteenth to early twentieth century, such as Karl Heinrich Ulrichs, Richard von Krafft-Ebing, Magnus Hirschfeld, Havelock Ellis, Carl Jung and Sigmund Freud, as well as many gender variant homosexual people themselves. However, this understanding of homosexuality as sexual inversion was disputed at the time, and through the second half of the twentieth century, gender identity came to be increasingly seen as a phenomenon distinct from sexual orientation. Transgender and cisgender people may be attracted to men, women, or both, although the prevalence of different sexual orientations is quite different in these two populations (see sexual orientation of transwomen). An individual homosexual, heterosexual or bisexual person may be masculine, feminine, or androgynous, and in addition, many members and supporters of lesbian and gay communities now see the "gender-conforming heterosexual" and the "gender-nonconforming homosexual" as negative stereotypes. However, studies by J Michael Bailey and KJ Zucker have found that a majority of gay men and lesbians report being gender-nonconforming during their childhood years.
The majority of transgender people today identify with the sexual orientation that corresponds with their gender; meaning that a transwoman who is solely attracted to women would often identify as a lesbian. Female-attracted transmen often consider themselves straight men, yet some participate in the lesbian community.
For these reasons, the terms gynephilia and androphilia are occasionally (but increasingly) used when referring to the sexual orientation of transgender and intersex people (and occasionally, cisgender people), because rather than focusing on the sex of the subject, they only describe that of the object of their attraction. The third common term that describes sexual orientation, bisexuality, makes no claim about the subject's sex or gender identity. (See also Pansexuality)

Heterosexual

Heterosexual
Heterosexuality refers to sexual behavior with, or attraction to, people of the opposite sex, or to a heterosexual orientation. As a sexual orientation, heterosexuality refers to "an enduring pattern of or disposition to experience sexual, affectional, or romantic attractions primarily to "persons of the opposite sex"; it also refers to "an individual’s sense of personal and social identity based on those attractions, behaviors expressing them, and membership in a community of others who share them." The term is usually applied to human beings, but it is also observed in all mammals. The physical action of heterosexual fertilization is the only means of sexual reproductive capability among humans without the use of assisted reproductive technology. The associations with romantic love and identity in addition to its original, exclusively sexual, meaning dates back to early human societies and gender role separation. As such, gender role separation has been the subject of considerable scholarly commentary and study in human societies since the earliest written records. Heterosexuality has been more intensely studied by medicine and later biology disciplines, and more recently that of psychology. Heterosexuality, along with bisexuality and homosexuality together make up the heterosexual-homosexual continuum.

Homosexuality

Homosexuality

Homosexuality refers to attraction or sexual behavior between people of the same sex, and/or to a sexual orientation. As an orientation, homosexuality refers to "an enduring pattern of or disposition to experience sexual, affectional, or romantic attractions primarily to" people of the same sex; "it also refers to an individual’s sense of personal and social identity based on those attractions, behaviors expressing them, and membership in a community of others who share them." Homosexuality, bisexuality, and heterosexuality together make up the three main categories of sexual orientation and are part of the heterosexual-homosexual continuum. The number of people identifying as homosexual— and the proportion having homosexual experiences— are quantities which have been difficult for researchers to estimate reliably. Many recent studies indicate a prevalence of 2% to 13% of the population. The prevalence of male homosexual orientation may vary over time and across societies in part because of variations in fertility rate or family size.
Sexual orientation is also distinguished from other aspects of sexuality, "including biological sex (the anatomical, physiological, and genetic characteristics associated with being male or female), gender identity (the psychological sense of being male, female or other), and social gender role (adherence to cultural norms defining feminine and masculine behavior)."
Etymologically, the word homosexual is a Greek and Latin hybrid with homos (sometimes confused with an unrelated Latin word for "man", as in Homo sapiens) deriving from the Greek word for same, thus connoting sexual acts and affections between members of the same sex, including lesbianism. Gay generally refers to male homosexuality, but is sometimes used in a broader sense to refer to all LGBT people. In the context of sexuality, lesbian denotes female homosexuality.
Homosexual relationships and acts have been admired as well as condemned throughout recorded history, depending on the form they took and the culture in which they occurred. Since the end of the 1800s (especially in the West), there has been a movement towards increased visibility, recognition and legal rights for people engaging in certain homosexual activities, including the rights to marriage and civil unions, adoption and parenting, employment, military service, and equal access to health care.

Bisexuality

Bisexuality
Bisexuality refers to sexual behavior with or physical attraction to people of both genders (male and female), or a bisexual orientation. People who have a bisexual orientation "can experience sexual, emotional, and affectional attraction to both their own sex and the opposite sex"; "it also refers to an individual’s sense of personal and social identity based on those attractions, behaviors expressing them, and membership in a community of others who share them." It is one of the three main classifications of sexual orientation, along with a heterosexual and a homosexual orientation. Individuals who do not experience sexual attraction to either sex are known as asexual.
According to Alfred Kinsey's research into human sexuality in the mid-20th century, many humans do not fall exclusively into heterosexual or homosexual classifications but somewhere between. The Kinsey scale measures sexual attraction and behavior on a seven-point scale ranging from 0 (exclusively heterosexual) to 6 (exclusively homosexual). According to Kinsey's study, a substantial number of people fall within the range of 1 to 5 (between heterosexual and homosexual). Although Kinsey's methodology has been criticized, the scale is still widely used in describing the continuum of human sexuality.
Bisexuality has been observed in various human societies and elsewhere in the animal kingdom throughout recorded history. The term bisexuality, however, like the terms hetero- and homosexuality, was only coined in the 19th century.

Despite misconceptions, bisexuality does not require that a person be attracted equally to both sexes. In fact, people who have a distinct but not exclusive preference for one sex over the other may still identify themselves as bisexual. A recent study by researchers Gerulf Rieger, Meredith L. Chivers, and J. Michael Bailey, which attracted media attention in 2005, purported to find that bisexuality is extremely rare in men. This was based on results of controversial penile plethysmograph testing when viewing pornographic material involving only men and pornography involving only women. Critics state that this study works from the assumption that a person is only truly bisexual if he or she exhibits virtually equal arousal responses to both opposite-sex and same-sex stimuli, and have consequently dismissed the self-identification of people whose arousal patterns showed even a mild preference for one sex. Some researchers say that the technique used in the study to measure genital arousal is too crude to capture the richness (erotic sensations, affection, admiration) that constitutes sexual attraction. The study, and The New York Times article which reported it, were subsequently criticized as flawed and biphobic.FAIR also criticised the study.
Because bisexuality is often perceived as an ambiguous personal choice made between homosexuality and heterosexuality, bisexuals form a heterogeneous group and the relations between their behaviors, feelings, and identities are not always accepted as consistent. Many who might be classified as bisexual on the basis of their primary sexual behavior self-identify as homosexual. Heterosexual people who engage in occasional homosexual behavior could be considered bisexual, but may not identify as such. Those who believe that sexuality and sexual orientation is a distinctly defined aspect of the character consider this ambiguity problematic. Some people who engage in bisexual behavior may be supportive of homosexual people, but still self-identify as heterosexual; others may consider any labels irrelevant to their positions and situations. In 1995, Harvard Shakespeare professor Marjorie Garber made the academic case for bisexuality with her 600 page, Vice Versa: Bisexuality and the Eroticism of Everyday Life in which she argued that most people would be bisexual if not for "repression, religion, repugnance, denial" and "premature specialization."
Bisexuality is often misunderstood as a form of adultery or polyamory, and a popular misconception is that bisexuals must always be in relationships with men and women simultaneously. Rather, individuals attracted to both males and females, like people of any other orientation, may live a variety of sexual lifestyles. These include lifelong monogamy, serial monogamy, polyamory, polyfidelity, promiscuity, group sex, and celibacy. For those with more than one sexual partner, these may, or may not, all be of the same gender. Unfortunately, bisexuals are often considered suspect by both homosexuals and heterosexuals because they are not recognized as being emotionally and physically committed to either a gay or lesbian existence, nor heterosexual society in general.

Diffrent Kinds Of Sex

Diffrent Kinds Of Sex

Vaginal Sex

Vaginal Sex
Vaginal sexual intercourse, also called coitus, is the human form of copulation. While a purpose and effect is reproduction, it is often performed exclusively for pleasure and/or as an expression of love and emotional intimacy. Sexual intercourse typically plays a powerful bonding role; in many societies it is normal for couples to have frequent intercourse while using birth control, sharing pleasure and strengthening their emotional bond through sex even though they are deliberately avoiding pregnancy.
Sexual intercourse may also be defined as referring to other forms of insertive sexual behavior, such as oral sex and anal intercourse. The phrase to have sex can mean any or all of these behaviors, as well as other non-penetrative sex acts not considered here.
Coitus may be preceded by foreplay, which leads to sexual arousal of the partners, resulting in the erection of the penis and natural lubrication of the vagina.
To engage in coitus, the erect penis is inserted into the vagina and one or both of the partners move their hips to move the penis backward and forward inside the vagina to cause friction, typically without fully removing the penis. In this way, they stimulate themselves and each other, often continuing until orgasm in either or both partners is achieved. Penetration by the hardened erect penis is also known as intromission, or by the Latin name immissio penis (Latin for "insertion of the penis").
Coitus is the basic reproductive method of humans. During ejaculation, which usually accompanies male orgasm, a series of muscular contractions delivers semen containing male gametes known as sperm cells or spermatozoa from the penis into the vagina.
The subsequent route of the sperm from the vault of the vagina is through the cervix and into the uterus, and then into the fallopian tubes. Millions of sperm are present in each ejaculation, to increase the chances of one fertilizing an egg or ovum. When a fertile ovum from the female is present in the fallopian tubes, the male gamete joins with the ovum, resulting in fertilization and the formation of a new embryo. When a fertilized ovum reaches the uterus, it becomes implanted in the lining of the uterus, known as endometrium, and a pregnancy begins.
Unlike most species, human sexual activity is not linked to periods of estrus and can take place at any time during the reproductive cycle, even during pregnancy.

Oral Sex

Oral Sex
Oral sex refers to sexual activities involving the stimulation of the genitalia by the use of the mouth, tongue, teeth or throat. Cunnilingus refers to oral sex performed on a woman while fellatio and irrumatio refer to oral sex performed on a man. Analingus refers to oral stimulation of a person's anus. Oral stimulation of other parts of the body (as in kissing and licking) is usually not considered oral sex.
People may engage in oral sex as part of foreplay before sexual intercourse, or during or following intercourse. It may also be performed for its own sake.

Oral sex may be practiced in both heterosexual and homosexual sexual contexts. In heterosexual contexts, oral sex is used by some couples as a method of contraception and may be chosen as an alternative to sexual intercourse for this reason. Oral sexual activities are not effective methods of preventing sexually transmitted diseases (STDs), although some forms of STD are believed to be less easily spread in this way.[1][2]
A report issued in September 2005 by the National Center for Health Statistics was the basis of an article in the September 26, 2005 issue of Time magazine. The report comes from the results of a computer-administered survey of over 12,000 Americans between the ages of 15 and 44, and states that over half the teenagers questioned have had oral sex. While some headlines have interpreted this as evidence that oral sex among teenagers is "on the rise," this was the first comprehensive study of its kind to examine the matter.[3]
As with mutual masturbation and other forms of outercourse many people do not consider oral sex to be "sex" in the same way as penetrative intercourse[4] and regard it as "third base." Thus, for many people, oral sex can be seen as one way of experiencing sexual pleasure before losing one's virginity.

Anal Sex

Anal Sex
Anal sex most often refers to the sex act involving insertion of the penis into the anus.[1] The term anal sex can also sometimes include other sexual acts involving the anus, including but not limited to anilingus and fingering.
It is a form of sexual behavior considered to be comparatively high in risk, due to the vulnerability of the tissues and the septic nature of the anus.[2] As the rectal mucosa provides little natural lubrication, a personal lubricant is most often required or preferred when penetrating the anus.

Tantric Sex

Tantric Sex
Have you ever experienced a moment of sexual ecstasy? How did it make you feel? Exhilarated? Luminous? Deeply connected? Intense sexual experiences are one of our greatest sources of pleasure.
At the same time, sex is often regarded with an equal measure of fear and fascination. We may crave sexual intimacy to the core of our being, yet also take great pains to avoid it. We may wish to be touched with all of our heart, yet fear our own vulnerability. We may long to rekindle lost passion, but have forgotten how to light the fire.
The practice of Tantra shows us how to reclaim the sexual intimacy that is our birthright. And through this most ancient of arts, we may discover new joys of the erotic and expand mere moments of sexual ecstasy into a lifetime of sexual bliss. At a time when the stresses, fears and distractions of daily life threaten so many relationships, the age-old practice of Tantra shows us how to open our hearts, our emotions and our sexuality.
What Is Tantra?Although Tantra has long been practiced in many eastern cultures, it is just beginning to flourish in the United States. Born in India more than 6,000 years ago, Tantra emerged as a rebellion against organized religion, which held that sexuality should be rejected in order to reach enlightenment.
Tantra challenged the acetic beliefs of that time, purporting that sexuality was a doorway to the divine, and that earthly pleasures, such as eating, dancing and creative expression were sacred acts.
The word Tantra means "to manifest, to expand, to show and to weave." In this context, sex is thought to expand consciousness and to weave together the polarities of male (represented by the Hindu god, Shiva), and female (embodied by the Hindu goddess, Shakti), into a harmonious whole.
Couples need not adopt the Tantric pantheon in order to benefit from the sexual wisdom of this ancient art. Tantric sexual practices teach us to prolong the act of making love and to utilize potent orgasmic energies more effectively.
Tantra is also health enhancing. "Sexual energy is one of our most powerful energies for creating health," says Christiane Northrup, M.D., author of "Women's Bodies, Women's Wisdom."
"By using sexual energy consciously…we can tap into a true source of youth and vitality."
How Is Tantric Sex Unique?In the West, we sometimes view sex as a source of recreation rather than a means of transformation. The goal may be to reach orgasm rather than to pleasure our lover or to connect with him or her more fully.
This kind of lovemaking, say sex experts, has a distinct beginning and ending, with a climax somewhere in between and an average duration of 10 to 15 minutes. Given that women can take about 20 minutes just to reach full arousal, this type of sexual experience can be deeply unsatisfying.
In the Tantric model, the sexual experience is seen as a dance with no beginning or end. There is no goal, only the present moment of exquisite union. For this reason, lovemaking is meditative, expressive and intimate. Tantra teaches lovers how to extend the peak of their sexual ecstasy so that women and men can experience several orgasms in a single sexual encounter.
Leading teachers of Tantra suggest that even men who experience premature ejaculation can learn how to extend orgasm, and, with practice, to enjoy multiple orgasms. One of the most well known advocates of Tantra is the musician, Sting, who credits his fulfilling sex life to this ancient art. With ingredients such as love, trust and mutual respect, the magic of Tantra is available to couples of all ages and levels of sexual experience.
Beginning Tantric Sex TechniquesThe following exercises will help you reconnect with your body and with your partner in a profound way. As you move through these steps, do not focus on intercourse as the ultimate goal. Instead, simply enjoy giving and receiving pleasure using gentle touch and loving words.
Communicate with your lover to discover what he or she finds most arousing. Try to spend several weeks practicing the Tantric Intimacy Exercises without necessarily engaging in intercourse. For many, experiencing these erotic exercises with no pressure to "go all the way" helps release sexual guilt, builds trust and reawakens sexual desire. Enjoy!
Tantric Sex — Welcoming LoveMake time for each other every week. Plan a sexual rendezvous at least once per week. Set aside an hour or more of uninterrupted time to be together. Although it may be difficult to find the time or to manage children, you won't be able to benefit from Tantra if your relationship is not a priority.
Create an inviting atmosphere. Whether you meet in your bedroom, living room or another space in your house, creating a sacred space for each other will help relax you and bring you into the moment. Candles, fresh flowers, erotic art, finger foods and tantalizing aromas can transform any room into a temple of sexual delight. Even something as simple as dimming the lights and playing erotic music will help create a welcoming environment.
Dress provocatively. Or, wear nothing at all. Experiment with clothing or accessories that make you feel sexy and excite your partner.
Tantric Intimacy ExercisesUse ritual to develop intimacy. Begin your journey with a ritual. This may be something as simple as feeding each other delicious foods or sharing a glass of wine in the nude. Some couples enjoy bathing together in order to attune to each other.
Take time to wash each other with loving care. Water relaxes the body and is a symbol of sexuality. Massaging each other is also an excellent way to fuse your energies. Or, read poetry to each other, dance, play, listen to music—work on developing new intimacy skills. Most importantly, use this time to communicate,sharing what you adore about each other. The idea is to help each partner feel loved and cherished.
In order to fully focus on each other (rather than on the goal of sex), some lovers experiment with various intimate rituals for several weeks before moving on to the next steps or engaging in intercourse. This is a wonderful way to strengthen the bonds of love and ignite passion.
Harmonize your breathing. "The only time we ever think about breathing is when we have trouble doing it, yet conscious breathing can be a powerful aid in sexual growth," according to sex therapist Marty Klein, Ph.D. of Palo Alto, California. Breathing exercises also quiet the mind and help you focus on each other.
Try this exercise: Sit quietly, cross-legged, facing each other. Rest your hands on your knees with your palms facing up. As you gaze into your partner's eyes, take soft, but deep breaths. Keep your eyes open, gazing beyond the eyes, into the soul. Although this may feel awkward at first, sustained eye contact is essential for building intimacy.
Now, pay attention to your breathing. Begin to breathe at the same pace, bringing air slowly in through your nose and exhaling through your mouth. Maintain eye contact while you breathe together. Practice this exercise until you can sustain eye contact and harmonized breathing for about 10 minutes. Then, you may move into the next exercise.
Experiment with erotic touch to fully appreciate your partner. This most pleasurable practice will help you become better lovers. Although you should continue to maintain eye contact, don't worry about keeping your breath synchronized. Breath will come back into play later. Guide your partner as you take turns stimulating each other. Describe exactly how you would like to be touched.
Share your desires in an encouraging way, making requests in a clear and loving manner. For example, ask your lover to caress your clitoris or penis (or any erogenous zone), encouraging him or her to apply more or less pressure, to stroke in a specific pattern, to use the tongue, etc. Thank your lover and let him or her know with words or sounds that you are enjoying this sensual touch.
Once you become comfortable with this process, you may wish to create a "pleasure chest." Include whatever excites you and your partner—a feather, vibrator, massage oil, blindfold, soft fabric, erotica and loving notes to each other are just a few ideas. As you pleasure each other, don't be shy about asking for something different. This is your time for appreciation, experimentation and for taking responsibility for your own fulfillment by asking for what you want.
From here, you may wish to embark on your own erotic journey. Create amorous adventures together, exploring new and creative ways to awaken each other's bodies and minds. Then, you will be ready for Tantric lovemaking.
Basic Tantric Sex TechniquesThe Tantric tradition emphasizes preparation for lovemaking. Erotic rituals such as those described above focus on exchanging pleasures, awakening the senses and allowing couples to communicate on deep physical and emotional levels.
During this time, lovers are able to establish an intimate connection that can be maintained and heightened as they transition into the sexual dimension. Intimacy exercises are a form of extended foreplay, helping titillate lovers for the sex that is to come and create the optimal conditions for Tantric lovemaking.
As you experiment with Tantric techniques, don't worry whether you are doing something the "right" way. Tantra does not judge right or wrong, good or bad. Ultimately, your pleasure is what matters most.
Moving Toward Sexual BlissAs you transition into sex, the idea is to maintain a state of sexual ecstasy for as long as possible. Tantric lovemaking is not result-oriented, but rather, timeless and unstructured.
Maintain a deep level of intimacy. Continue to gaze into each other's eyes as much as possible. Sprinkle your lover's face, neck and shoulders with light kisses and whisper words of love and encouragement. Help each other feel loved and desired.
Keep it slow. A long, slow build helps men control orgasm and piques women's arousal. According to Tantric teacher, Robert Frey, the longer you linger in this process of building energy, the longer men can resist ejaculation. During this time, focus on each other. If your thoughts should wander, gently bring your attention back to the present, concentrating on your lover and the magic of the moment at hand.
Bring your attention back to your breath. Resist the urge to breathe quickly. Quick breathing or panting creates arousal, speeding you toward orgasm. Instead, take long, slow, deep breaths from the belly, exhaling gradually. You may match your breath to that of your partner, or try breathing alternately—as you inhale, your partner exhales. This moves energy back and forth and connects you to your lover.
Vary your positions to explore your duality. Different sex positions add to sexual pleasure and balance male and female energies. When lovers release themselves from gender roles, they are free to engage in deeper, more intimate sex. Men realize their sexual potential through surrender, by being soft and open, gentle and vulnerable. Women, in turn, can direct and initiate. As you experiment with different positions, some male-dominant, some female-dominant, explore your capacity to be strong and gentle, generous and receptive.
Multiple Orgasms for MenTantric sex distinguishes between the experiences of orgasm and ejaculation. Although they often happen at the same time, men are capable of having orgasms without ejaculating. Ejaculatory control is what makes it possible for Tantric lovers to capture and extend the magical energy of orgasm. By holding back, men can experience a series of "mini-orgasms."
This does not mean that you are never to ejaculate, but that you can control your climax. The essence, say Tantric experts, is to catch a wave of energy and to surf the edge without going over. Use these strategies to stay atop the wave:
Pump the PC muscles. The pubococcygeal (PC) muscles, which run from your public bone to your tailbone, are the ultimate sex muscles. These are the same muscles used to stop the flow of urine. If properly conditioned, the PCs enable you to stop ejaculation while continuing to enjoy sex. Kegel exercises are the best way to tone the PCs.
Here's how: Contract your PC muscles three times per day, squeezing 20 to 25 repetitions. This is a simple exercise that you can do at anytime. Just don't overdo it. After a month of conditioning, try to extend the squeeze, holding each contraction for two seconds. Gradually work up to 10 seconds. Once your PCs are in top shape, you will be able to pump them in order to ride the orgasmic wave without gliding over the brink too soon.
Relax. Although it sounds paradoxical, it's important for men to stay relaxed during high states of arousal. If you feel the undulations of ejaculation, take a slow, deep breath and stop making love long enough for your arousal to subside. Relax and try to direct energy from your penis up through your body.
Take this time to talk to your partner or to draw several slow, deep breaths. By experimenting, you will discover how much "time out" you require before catching the next wave. The idea is to allow yourself enough time for the intensity to subside, but not so much that you lose your erection.
Put it all together. When you and your partner make love, thrust slowly, allowing your arousal to build gradually. Before your excitement mounts, relax for a moment, tighten your PC muscles and take a deep breath. Resume your lovemaking, continuing to generate excitement.
Then, relax again, hold your PCs and breathe. Continue to ride this swell until you near the crest. Then, open your eyes, clamp down on your PC muscles and take a deep breath to experience the joy of orgasm without ejaculating. Since these techniques take practice, expect a few "wipe outs" before you achieve mastery.
Freeing Female OrgasmIt is often said that a woman's most powerful sex organ lies between her ears. Since desire can be short-circuited by fear, guilt, stress and a host of other distracting thoughts, women often need to concentrate on feeling rather than thinking when making love. Taking breaks to pleasure each other, manually and orally, is a great way to ward off any lingering diversions and to coax one or more orgasms.
Clitoral stimulation. Most women require stimulation of the clitoris and labia (the inner lips surrounding the clitoris) during sex to reach orgasm. Prolonged clitoral touch with a gentle, patient hand is, for many, the key to sexual ecstasy. Use sounds and positive words to guide your lover, showing your partner how to stroke you just so.
The sacred spot. The mythic Grafenberg Spot (G-spot) is referred to in Tantra as the "sacred spot." This potent and mysterious erogenous zone is located about two to three inches up on the front side of the vaginal channel. When your lover is aroused, slip your ring finger into her vagina allowing your fingertip to brush against the inner wall.
The G-spot is between the size of a pea and a quarter with a slightly rippled texture. For some women, though not for all, gentle stimulation can induce powerful orgasms and even female ejaculate. However, take care not to over-stimulate this sensitive spot.

The Art Of Making Love

The Art Of Making Love

Karma Sutra

The Kama Sutra is the world's oldest book on the pleasures of sensual living. There is no one single author for the text. It was originally compiled in the 3rd century by the Indian sage Vatsyayana, who lived in northern India. Vatsyayana claimed to be a celibate monk, and that his work in compiling all of the sexual knowledge of ages past was for him a form of meditation and contemplation of the deity. Written in a rather complex form of Sanskrit, the Kama Sutra is the only surviving textual account of that period of ancient Indian history. In scholarly circles it has been widely consulted by scholars trying to understand the society and social mores of that period. The title of the text, Kama Sutra, literally means "a treatise on pleasure." Far more complex than a mere listing of contortionist sexual positions, the Kama Sutra provides a comprehensive manual of living for the good life. Although the central character of the Kama Sutra is the citizenly man-about-town, the text was written to be read by and provide detailed advice for both men and women.
The basic tenet of the Kama Sutra is that in order for marriages to be happy, both man and woman should be well-versed in the arts of pleasure, both carnal and cerebral. The topics explored include Society and Social Concepts, On Sexual Union, About the Acquisition of a Wife, About a Wife, About the Wives of Other Men, About Courtesans, and On the Means of Attracting Others to Yourself. The book contains detailed advice on what a man must do to win over a woman, what a woman must do to win over a man, the states of a woman's mind, the role of a go-between, and the reasons why women might reject the advances of men. In terms of choosing a mate, the Kama Sutra advises on whether to consider fellow students or childhood friends. It provides charts that categorize male and female physical types and their compatibility with their lover's body. Varieties of embracing, kissing, scratching, biting, oral sex, and sexual intercourse are elaborated. The text also incorporates instruction on extramarital relationships, including with "the wives of other men," and devotes many pages to the methods of seduction and methods of extortion practiced by the courtesan. Finally, in case all of that knowledge should fail in winning the love that one seeks, the final chapter of the Kama Sutra contains recipes for tonics, powders, and foods that have the power to help attract others to oneself.
Some people refer to the Kama Sutra as a marriage manual, but it is a far cry from the monogamous and dutiful tomes that Westerners produced as part of the proliferation of advice manuals in the Victorian era. One of the central figures of the Kama Sutra is the courtesan, who must also master and practice a variety of arts in learning how to please and coerce her man. What is especially unique about the Kama Sutra is that it maintains a special focus on creating pleasure for the woman. A man who fails to provide and bring about those pleasures is subject to a woman's recourse, that is, to seek pleasure elsewhere where she may find it.
As the 'original' study of sexuality, the Kama Sutra became the fountainhead of all subsequent compilations, including the 15th century Ananga-Ranga which is a revised version and builds upon Vatsyayana's basic tenets. Yet because of the complex and rather inaccessible style of Sanskrit in which it was written, the Kama Sutra for many centuries fell into obscurity. Scholars of Sanskrit and ancient India did not much consult it. It was not until the late 19th century that the Kama Sutra again began to resume its former prominence in the textual traditions of India. That resurgence came about after the 1870s when Sir Richard Burton, the noted linguist and Arabic translator, was working with his collaborators, both Indian and British, on producing a translation of the Ananga-Ranga. In pursuing the many references to Vatsyayana with the text, Burton led the Pundits back to the Kama Sutra and an English translation was produced. Burton's persistence in publishing the Kama Sutra in the West, and the interest the text generated in both India and abroad, has led to a proliferation of translations and versions of the original masterpiece.


The Ananga-Ranga

The 15th century Ananga-Ranga is an updated version of the Kama Sutra, written in far more accessible Sanskrit than its earlier predecessor. As a result, for many centuries the Ananga-Ranga actually superceded the Kama Sutra in being the text of choice to consult for knowledge about sexual pleasure. The writing of the Ananga-Ranga was commissioned by the nobleman Ladakhana for one of the Lodi Dynasty's monarch. The Lodis were part of the powerful Delhi Sultanate who ruled northern India before the Mughal Dynasty took its place. Kalyanamalla, the author of the Ananga-Ranga, was a Hindu poet, who drew heavily upon the Kama Sutra in preparing his text. Kalyanamally wrote in an accessible Sanskrit style, and its royal Muslim patronage assured that the text enjoyed a wide circulation among the medieval Muslim empires. Versions of the Ananga-Ranga also appeared in Arabic, Persian, and Urdu.
Opening with a dedication to Ladakhana, the text's patron, the book contains prescriptive advice for married couples, and for their conduct both social and sexual. It begins with a detailed description of female bodies, and includes "centers of passion," erogenous zones, classifications of body types and the timeliness of their potential sexual pleasures. Classification and compatibility of males and females by their genital size is explored in various combinations and to their degree of passion. Many scholars speculate that Kalyanamalla lived in a more sexist society than earlier writers, noting that Kalyanamalla deviates from other writers by neglecting to provide normative advice for producing women's pleasure, such as the use of fingers, a method that other texts heartily endorse. The title of the book, Ananga-Ranga, has been variously translated as "Stage of the Bodiless One," "The Hindu Art of Love," and "Theatre of the Love God," among others.
As part of the romanticism of colonial rule, Europeans sought out Eastern texts to bring ancient wisdom to the modern world. However, the Orientalist engagement in the Ananga-Ranga ironically led to the text's decreased relevance, and the prominence of the earlier Kama Sutra. Burton's experiences living in India as a part of the British military and his fascination with the sexual practices of Oriental societies, coupled with his desire to bring this knowledge to the attention of his co-citizens of the British metropole, led to his interests in the canon of sexual knowledge preserved in Sanskrit texts. Because of the relative popularity of the Ananga-Ranga among the Sanskrit specialists, it was natural that it should be the text of choice for Burton's purposes. When reviewing their translations, however, Burton made note of the many references made to an earlier compilation by Vatsyayana. Burton believed that his earlier text, the Kama Sutra, was a far more foundational work, and requested that the Pundits locate a copy. Because of its centuries of relative neglect, the Kama Sutra at this stage only existed in parts. The text had to be re-compiled from Sanskrit manuscript library collections across India and in the Princely States. Once the text was translated into English, its popularity grew, and Indian scholars set aside the Ananga-Ranga with a renewed interest in its predecessor.

Erotica

Erotica
Erotica (from the Greek Eros—"desire") or "curiosa," works of art, including literature, photography, film, sculpture and painting, that deal substantively with erotically stimulating or sexually arousing descriptions. Erotica is a modern word used to describe the portrayal of the human anatomy and sexuality with high-art aspirations, differentiating such work from commercial pornography. "Curiosa" is generally used to refer to erotica and pornography as discrete, collectible items, usually in published or printed form.
Various sub-genres of erotica exist. As with fiction as a whole, there are erotic stories with a science fiction, fantasy, horror or romance focus. Additionally, erotica can also focus on specific sexual behavior or fetishes such as BDSM, wearing uniforms, cross-dressing, polygamy and sexual promiscuity. Fan fiction featuring characters engaging in male homosexual acts has become known as slash fiction.

Distinction is often made between erotica and pornography (the depiction of acts in a sensational manner so as to arouse a quick intense emotional reaction)(as well as the lesser known genre of sexual entertainment, ribaldry), although depending on the viewer they may seem one and the same. Pornography's objective is the graphic depiction of sexually explicit scenes. Pornography is often described as exploitative or degrading. One person's pornography is another's erotica, and vice-versa. In other words, if a politician or priest finds a work containing only consenting adults "perverted", then it says more about the mental state of the accuser than the intentions of the photographer or viewer. The dictionary also uses different emotive words to describe the same product. Erotica is "Explicitly sexual literature or art, concerning or arousing sexual pleasure." Pornography is "Writings, pictures, films etc. designed to stimulate sexual excitement." Even the dictionary's authors couldn't avoid bringing emotion into their definitions. Erotica is described using the gentle word "arousing" whereas pornography gets the "stimulate", a much colder, clinical definition.
In December of 2007 one of the world's largest collections of pornography and erotica, the L'Enfer collection housed at the Bibliotheque Nationale in Paris, France, was opened for the public. Marie-Franoise Quignard, one of the collection's curators, tried to distinguish between the different elements in the collection:
"There is a photograph of an act of oral sex by the artist Man Ray.... For some reason, I find that this goes just too far. Perhaps because it is a photograph and so real, while engravings or lithographs, give you a certain distance and idealisation. Man Ray confronts you point-blank here with something which should, perhaps, better remain intimate.

The Canadian Supreme Court wrestled with the line between pornography and erotica going back to 1962's case Brodie v. the Queen, which involved D. H. Lawrence's erotic classic Lady Chatterley's Lover. In its decision on whether Lawrence's book was obscene, the court noted that it "has none of the characteristics that are often described in judgments dealing with obscenity --dirt for dirt's sake, the leer of the sensualist, depravity in the mind of an author with an obsession for dirt, pornography, an appeal to a prurient interest, etc." In 1992, the Canadian high court changed its 'dirt for dirt's sake' test until it ruled in the case of sex shop operator R. v. Butler that a work is pornographic if it is "degrading and dehumanizing."This remains the central test in Canadian courts.
In Ukraine, the national expert commission on public moral protection derived criteria on how to distinguish pornography from erotica. According to the order, pornography is a detailed image of coitus and naked genitals for sexual stimulation without any artistic or educating aims. For an image to be considered erotica, the number of images can not exceed 20 percent of the total, nor 50 percent of the whole of an image. Erotica is a portrayal “without open visualization of genital interaction”. Pornography, according to the national expert commission, is a portrayal of group and homosexual intercourse, scenes of sexual violence and/or sexual perversions.

The Dark Side of Sex

The Dark Side of Sex

Sexually Transmitted Diseases

A sexually transmitted disease (STD), also known as sexually transmitted infection (STI) or venereal disease (VD), is an illness that has a significant probability of transmission between humans or animals by means of sexual contact, including vaginal intercourse, oral sex, and anal sex. While in the past, these illnesses have mostly been referred to as STDs or VD, in recent years the term sexually transmitted infection (STI) has been preferred, as it has a broader range of meaning; a person may be infected, and may potentially infect others, without showing signs of disease. Some STIs can also be transmitted via use of an IV drug needle after its use by an infected person, as well as through childbirth or breastfeeding. Sexually transmitted infections have been well known for hundreds of years.

Until the 1990s, STDs were commonly known as venereal diseases : Veneris is the Latin genitive form of the name Venus, the Roman goddess of love. Social disease was another euphemism.
Public health officials originally introduced the term sexually transmitted infection, which clinicians are increasingly using alongside the term sexually transmitted disease in order to distinguish it from the former. According to the Ethiopian Aids Resource Center FAQ, "Sometimes the terms STI and STD are used interchangeably. This can be confusing and not always accurate, so it helps first to understand the difference between infection and disease. Infection simply means that a germvirus, bacteria, or parasite — that can cause disease or sickness is present inside a person’s body. An infected person does not necessarily have any symptoms or signs that the virus or bacteria is actually hurting his or her body; they do not necessarily feel sick. A disease means that the infection is actually causing the infected person to feel sick, or to notice something is wrong. For this reason, the term STI — which refers to infection with any germ that can cause an STD, even if the infected person has no symptoms — is a much broader term than STD."[1] The distinction being made, however, is closer to that between a colonization and an infection, rather than between an infection and a disease.
Specifically, the term STD refers only to infections that are causing symptoms. Because most of the time people do not know that they are infected with an STD until they start showing symptoms of disease, most people use the term STD, even though the term STI is also appropriate in many cases.
Moreover, the term sexually transmissible disease is sometimes used since it is less restrictive in consideration of other factors or means of transmission. For instance, meningitis is transmissible by means of sexual contact but is not labeled as an STI because sexual contact is not the primary vector for the pathogens that cause meningitis. This discrepancy is addressed by the probability of infection by means other than sexual contact. In general, an STI is an infection that has a negligible probability of transmission by means other than sexual contact, but has a realistic means of transmission by sexual contact (more sophisticated means — blood transfusion, sharing of hypodermic needles —are not taken into account). Thus, one may presume that, if a person is infected with an STI, e.g., chlamydia, gonorrhea, genital herpes, it was transmitted to him/her by means of sexual contact.

Many STDs are (more easily) transmitted through the mucous membranes of the penis, vulva, rectum, urinary tract and (less often - depending on type of infection)[citation needed] the mouth, throat, respiratory tract and eyes. The visible membrane covering the head of the penis is a mucous membrane, though it produces no mucus (similar to the lips of the mouth). Mucous membranes differ from skin in that they allow certain pathogens into the body.[2] Pathogens are also able to pass through breaks or abrasions of the skin, even minute ones. The shaft of the penis is particularly susceptible due to the friction caused during penetrative sex. The primary sources of infection in ascending order are venereal fluids, saliva, mucosal or skin (particularly the penis), infections may also be transmitted from feces, urine and sweat.[3] The amount required to cause infection varies with each pathogen but is always less than you can see with the naked eye.
This is one reason that the probability of transmitting many infections is far higher from sex than by more casual means of transmission, such as non-sexual contact—touching, hugging, shaking hands—but it is not the only reason. Although mucous membranes exist in the mouth as in the genitals, many STIs seem to be easier to transmit through oral sex than through deep kissing. According to a safe sex chart, many infections that are easily transmitted from the mouth to the genitals or from the genitals to the mouth, are much harder to transmit from one mouth to another.[4] With HIV, genital fluids happen to contain much more of the pathogen than saliva. Some infections labeled as STIs can be transmitted by direct skin contact. Herpes simplex and HPV are both examples. KSHV, on the other hand, may be transmitted by deep-kissing but also when saliva is used as a sexual lubricant.
Depending on the STD, a person may still be able to spread the infection if no signs of disease are present. For example, a person is much more likely to spread herpes infection when blisters are present (STD) than when they are absent (STI). However, a person can spread HIV infection (STI) at any time, even if he/she has not developed symptoms of AIDS (STD).
All sexual behaviors that involve contact with the bodily fluids of another person should be considered to contain some risk of transmission of sexually transmitted diseases. Most attention has focused on controlling HIV, which causes AIDS, but each STD presents a different situation.
As may be noted from the name, sexually transmitted diseases are transmitted from one person to another by certain sexual activities rather than being actually caused by those sexual activities. Bacteria, fungi, protozoa or viruses are still the causative agents. It is not possible to catch any sexually transmitted disease from a sexual activity with a person who is not carrying a disease; conversely, a person who has an STD got it from contact (sexual or otherwise) with someone who had it, or his/her bodily fluids. Some STDs such as HIV can be transmitted from mother to child either during pregnancy or breastfeeding.
Although the likelihood of transmitting various diseases by various sexual activities varies a great deal, in general, all sexual activities between two (or more) people should be considered as being a two-way route for the transmission of STDs, i.e., "giving" or "receiving" are both risky although receiving carries a higher risk.
Healthcare professionals suggest safer sex, such as the use of condoms, as the most reliable way of decreasing the risk of contracting sexually transmitted diseases during sexual activity, but safer sex should by no means be considered an absolute safeguard. The transfer of and exposure to bodily fluids, such as blood transfusions and other blood products, sharing injection needles, needle-stick injuries (when medical staff are inadvertently jabbed or pricked with needles during medical procedures), sharing tattoo needles, and childbirth are other avenues of transmission. These different means put certain groups, such as medical workers, and haemophiliacs and drug users, particularly at risk.
Recent epidemiological studies have investigated the networks that are defined by sexual relationships between individuals, and discovered that the properties of sexual networks are crucial to the spread of sexually transmitted diseases. In particular, assortative mixing between people with large numbers of sexual partners seems to be an important factor.
It is possible to be an asymptomatic carrier of sexually transmitted diseases. In particular, sexually transmitted diseases in women often cause the serious condition of pelvic inflammatory disease.

STD incidence rates remain high in most of the world, despite diagnostic and therapeutic advances that can rapidly render patients with many STDs noninfectious and cure most. In many cultures, changing sexual morals and oral contraceptive use have eliminated traditional sexual restraints, especially for women,[citation needed] and both physicians and patients have difficulty dealing openly and candidly with sexual issues. Additionally, development and spread of drug-resistant bacteria (e.g., penicillin-resistant gonococci) makes some STDs harder to cure. The effect of travel is most dramatically illustrated by the rapid spread of the AIDS virus (HIV-1) from Africa to Europe and the Americas in the late 1970s.[5]
Commonly reported prevalences of STIs among sexually active adolescent girls both with and without lower genital tract symptoms include chlamydia trachomatis (10 to 25%), Neisseria gonorrhoeae (3 to 18%), syphilis (0 to 3%), Trichomonas vaginalis (8 to 16%), and herpes simplex virus (2 to 12%).[citation needed] Among adolescent boys with no symptoms of urethritis, isolation rates include C. trachomatis (9 to 11%) and N. gonorrhoeae (2 to 3%).[citation needed]
In 1996, WHO estimated that more than 1 million people were being infected daily. About 60% of these infections occur in young people <25 years of age, and of these 30% are <20 years. Between the ages of 14 and 19, STDs occur more frequently in girls than boys by a ratio of nearly 2:1; this equalizes by age 20. An estimated 340 million new cases of syphilis, gonorrhea, chlamydia and trichomoniasis occurred throughout the world in 1999.

HIV/AIDS

HIV/AIDS
Acquired immune deficiency syndrome or acquired immunodeficiency syndrome (AIDS) is a disease of the human immune system caused by the human immunodeficiency virus (HIV).
This condition progressively reduces the effectiveness of the immune system and leaves individuals susceptible to opportunistic infections and tumors. HIV is transmitted through direct contact of a mucous membrane or the bloodstream with a bodily fluid containing HIV, such as blood, semen, vaginal fluid, preseminal fluid, and breast milk.
This transmission can involve anal, vaginal or oral sex, blood transfusion, contaminated hypodermic needles, exchange between mother and baby during pregnancy, childbirth, or breastfeeding, or other exposure to one of the above bodily fluids.
AIDS is now a pandemic. In 2007, an estimated 33.2 million people lived with the disease worldwide, and it killed an estimated 2.1 million people, including 330,000 children. Over three-quarters of these deaths occurred in sub-Saharan Africa, retarding economic growth and destroying human capital.
Genetic research indicates that HIV originated in west-central Africa during the late nineteenth or early twentieth century. AIDS was first recognized by the U.S. Centers for Disease Control and Prevention in 1981 and its cause, HIV, identified in the early 1980s.
Although treatments for AIDS and HIV can slow the course of the disease, there is currently no vaccine or cure. Antiretroviral treatment reduces both the mortality and the morbidity of HIV infection, but these drugs are expensive and routine access to antiretroviral medication is not available in all countries. Due to the difficulty in treating HIV infection, preventing infection is a key aim in controlling the AIDS epidemic, with health organizations promoting safe sex and needle-exchange programmes in attempts to slow the spread of the virus.

The symptoms of AIDS are primarily the result of conditions that do not normally develop in individuals with healthy immune systems. Most of these conditions are infections caused by bacteria, viruses, fungi and parasites that are normally controlled by the elements of the immune system that HIV damages.
Opportunistic infections are common in people with AIDS. HIV affects nearly every organ system.
People with AIDS also have an increased risk of developing various cancers such as Kaposi's sarcoma, cervical cancer and cancers of the immune system known as lymphomas. Additionally, people with AIDS often have systemic symptoms of infection like fevers, sweats (particularly at night), swollen glands, chills, weakness, and weight loss. The specific opportunistic infections that AIDS patients develop depend in part on the prevalence of these infections in the geographic area in which the patient lives.


Gonorrhea

Gonorrhea
Gonorrhea (also gonorrhoea) is caused by the bacterium Neisseria gonorrhoeae and is a common sexually transmitted infection. In the US, its incidence is second only to chlamydia.
Non-genital sites in which it thrives are in the rectum, the throat (oropharynx), and the eyes (conjunctiva). The vulva and vagina in women are usually spared because they are lined by stratified epithelial cells—in women the cervix is usually the first site of infection. Gonorrhea typically spreads during sexual intercourse. It can also be vertically transmitted, where infected mothers can pass gonorrhea to their newborn infants during delivery. This causes purulent conjunctivitis (eye infections) which, if left untreated, can lead to blindness. As prophylaxis against this, many countries routinely treat infants with eyedrops of erythromycin/silver nitrate at birth.

The incubation period is 2 to 30 days with most symptoms occurring between 4-6 days after being infected. A small number of people may be asymptomatic for a lifetime. Between 30% and 60% of people with gonorrhea are asymptomatic or have subclinical disease. Women may complain of vaginal discharge, difficulty urinating (dysuria), projectile urination, off-cycle menstrual bleeding, or bleeding after sexual intercourse. The cervix may appear anywhere from normal to the extreme of marked cervical inflammation with pus. Possibility of increased production of male hormones is common in many cases. Infection of the urethra (urethritis) causes little dysuria or pus. The combination of urethritis and cervicitis on examination strongly supports a gonorrhea diagnosis, as both sites are infected in most gonorrhea patients. Gonorrhea is caused by the Neisseria gonorrhoeae bacteria. The infection is transmitted from one person to another through vaginal, oral, or anal sexual relations, though transmission occurs rarely with safe sex practices of condom usage with lubrication.
Men have a 20% risk of getting the infection by having sexual relations with a woman infected with gonorrhea. Women have a 50% risk of getting the infection by having sexual relations with a man infected with gonorrhea. An infected mother may transmit gonorrhea to her newborn during childbirth, a condition known as ophthalmia neonatorum.
Less advanced symptoms, which may indicate development of pelvic inflammatory disease (PID), include cramps and pain, bleeding between menstrual periods, vomiting, or fever. It is not unusual for men to have asymptomatic gonorrhea. Men may complain of pain on urinating and thick, copious, urethral pus discharge (also known as gleet) is the most common presentation. Examination may show a reddened external urethral meatus. Ascending infection may involve the epididymis, testicles or prostate gland causing symptoms such as scrotal pain or swelling. Instances of blurred vision in one eye may occur in adults.
GC infection can also present as septic arthritis.

In men, inflammation of the epididymis (epididymitis); prostate gland (prostatitis) and urethral structure (urethritis) can result from untreated gonorrhea.
In women, the most common result of untreated gonorrhea is pelvic inflammatory disease, a serious infection of the uterus that can lead to infertility. Other complications include: perihepatitis, a rare complication associated with Fitz-Hugh-Curtis syndrome; septic arthritis in the fingers, wrists, toes, and ankles; septic abortion; chorioamnionitis during pregnancy; neonatal or adult blindness from conjunctivitis; and infertility. Neonates coming through the birth canal are given erythromycin ointment in eyes to prevent blindness from infection. The underlying gonorrhea should be treated; if this is done then usually a good prognosis will follow.

Chlamydia

Chlamydia
Chlamydia is a common sexually transmitted disease (STD) caused by the bacterium, Chlamydia trachomatis, which can damage a woman's reproductive organs. Even though symptoms of chlamydia are usually mild or absent, serious complications that cause irreversible damage, including infertility, can occur "silently" before a woman ever recognizes a problem. Chlamydia also can cause discharge from the penis of an infected man.

Chlamydia is the most frequently reported bacterial sexually transmitted disease in the United States. In 2006, 1,030,911 chlamydial infections were reported to CDC from 50 states and the District of Columbia. Under-reporting is substantial because most people with chlamydia are not aware of their infections and do not seek testing. Also, testing is not often done if patients are treated for their symptoms. An estimated 2,291,000 non-institutionalized U.S. civilians ages 14-39 are infected with Chlamydia based on the U.S. National Health and Nutrition Examination Survey. Women are frequently re-infected if their sex partners are not treated.

Chlamydia can be transmitted during vaginal, anal, or oral sex. Chlamydia can also be passed from an infected mother to her baby during vaginal childbirth.Any sexually active person can be infected with chlamydia. The greater the number of sex partners, the greater the risk of infection. Because the cervix (opening to the uterus) of teenage girls and young women is not fully matured and is probably more susceptible to infection, they are at particularly high risk for infection if sexually active. Since chlamydia can be transmitted by oral or anal sex, men who have sex with men are also at risk for chlamydial infection.

Chlamydia is known as a "silent" disease because about three quarters of infected women and about half of infected men have no symptoms. If symptoms do occur, they usually appear within 1 to 3 weeks after exposure.
In women, the bacteria initially infect the cervix and the urethra (urine canal). Women who have symptoms might have an abnormal vaginal discharge or a burning sensation when urinating. When the infection spreads from the cervix to the fallopian tubes (tubes that carry fertilized eggs from the ovaries to the uterus), some women still have no signs or symptoms; others have lower abdominal pain, low back pain, nausea, fever, pain during intercourse, or bleeding between menstrual periods. Chlamydial infection of the cervix can spread to the rectum.
Men with signs or symptoms might have a discharge from their penis or a burning sensation when urinating. Men might also have burning and itching around the opening of the penis. Pain and swelling in the testicles are uncommon.
Men or women who have receptive anal intercourse may acquire chlamydial infection in the rectum, which can cause rectal pain, discharge, or bleeding. Chlamydia can also be found in the throats of women and men having oral sex with an infected partner.

If untreated, chlamydial infections can progress to serious reproductive and other health problems with both short-term and long-term consequences. Like the disease itself, the damage that chlamydia causes is often "silent."
In women, untreated infection can spread into the uterus or fallopian tubes and cause pelvic inflammatory disease (PID). This happens in up to 40 percent of women with untreated chlamydia. PID can cause permanent damage to the fallopian tubes, uterus, and surrounding tissues. The damage can lead to chronic pelvic pain, infertility, and potentially fatal ectopic pregnancy (pregnancy outside the uterus). Women infected with chlamydia are up to five times more likely to become infected with HIV, if exposed.
To help prevent the serious consequences of chlamydia, screening at least annually for chlamydia is recommended for all sexually active women age 25 years and younger. An annual screening test also is recommended for older women with risk factors for chlamydia (a new sex partner or multiple sex partners). All pregnant women should have a screening test for chlamydia.
Complications among men are rare. Infection sometimes spreads to the epididymis (the tube that carries sperm from the testis), causing pain, fever, and, rarely, sterility.
Rarely, genital chlamydial infection can cause arthritis that can be accompanied by skin lesions and inflammation of the eye and urethra (Reiter's syndrome).

Herpes

Herpes
Genital herpes is a sexually transmitted disease (STD) caused by the herpes simplex viruses type 1 (HSV-1) or type 2 (HSV-2). Most genital herpes is caused by HSV-2. Most individuals have no or only minimal signs or symptoms from HSV-1 or HSV-2 infection. When signs do occur, they typically appear as one or more blisters on or around the genitals or rectum. The blisters break, leaving tender ulcers (sores) that may take two to four weeks to heal the first time they occur. Typically, another outbreak can appear weeks or months after the first, but it almost always is less severe and shorter than the first outbreak. Although the infection can stay in the body indefinitely, the number of outbreaks tends to decrease over a period of years.

Results of a nationally representative study show that genital herpes infection is common in the United States. Nationwide, at least 45 million people ages 12 and older, or one out of five adolescents and adults, have had genital HSV infection. Over the past decade, the percent of Americans with genital herpes infection in the U.S. has decreased.
Genital HSV-2 infection is more common in women (approximately one out of four women) than in men (almost one out of eight). This may be due to male-to-female transmission being more likely than female-to-male transmission.

HSV-1 and HSV-2 can be found in and released from the sores that the viruses cause, but they also are released between outbreaks from skin that does not appear to have a sore. Generally, a person can only get HSV-2 infection during sexual contact with someone who has a genital HSV-2 infection. Transmission can occur from an infected partner who does not have a visible sore and may not know that he or she is infected.
HSV-1 can cause genital herpes, but it more commonly causes infections of the mouth and lips, so-called “fever blisters.” HSV-1 infection of the genitals can be caused by oral-genital or genital-genital contact with a person who has HSV-1 infection. Genital HSV-1 outbreaks recur less regularly than genital HSV-2 outbreaks.

Most people infected with HSV-2 are not aware of their infection. However, if signs and symptoms occur during the first outbreak, they can be quite pronounced. The first outbreak usually occurs within two weeks after the virus is transmitted, and the sores typically heal within two to four weeks. Other signs and symptoms during the primary episode may include a second crop of sores, and flu-like symptoms, including fever and swollen glands. However, most individuals with HSV-2 infection never have sores, or they have very mild signs that they do not even notice or that they mistake for insect bites or another skin condition.
People diagnosed with a first episode of genital herpes can expect to have several (typically four or five) outbreaks (symptomatic recurrences) within a year. Over time these recurrences usually decrease in frequency. It is possible that a person becomes aware of the “first episode” years after the infection is acquired.

Genital herpes can cause recurrent painful genital sores in many adults, and herpes infection can be severe in people with suppressed immune systems. Regardless of severity of symptoms, genital herpes frequently causes psychological distress in people who know they are infected.
In addition, genital HSV can lead to potentially fatal infections in babies. It is important that women avoid contracting herpes during pregnancy because a newly acquired infection during late pregnancy poses a greater risk of transmission to the baby. If a woman has active genital herpes at delivery, a cesarean delivery is usually performed. Fortunately, infection of a baby from a woman with herpes infection is rare.
Herpes may play a role in the spread of HIV, the virus that causes AIDS. Herpes can make people more susceptible to HIV infection, and it can make HIV-infected individuals more infectious.

The signs and symptoms associated with HSV-2 can vary greatly. Health care providers can diagnose genital herpes by visual inspection if the outbreak is typical, and by taking a sample from the sore(s) and testing it in a laboratory. HSV infections can be diagnosed between outbreaks by the use of a blood test. Blood tests, which detect antibodies to HSV-1 or HSV-2 infection, can be helpful, although the results are not always clear-cut.

There is no treatment that can cure herpes, but antiviral medications can shorten and prevent outbreaks during the period of time the person takes the medication. In addition, daily suppressive therapy for symptomatic herpes can reduce transmission to partners.

Trichomoniasis

Trichomoniasis
Trichomoniasis is a common sexually transmitted disease (STD) that affects both women and men, although symptoms are more common in women.

Trichomoniasis is the most common curable STD in young, sexually active women. An estimated 7.4 million new cases occur each year in women and men.

Trichomoniasis is caused by the single-celled protozoan parasite, Trichomonas vaginalis. The vagina is the most common site of infection in women, and the urethra (urine canal) is the most common site of infection in men.The parasite is sexually transmitted through penis-to-vagina intercourse or vulva-to-vulva (the genital area outside the vagina) contact with an infected partner. Women can acquire the disease from infected men or women, but men usually contract it only from infected women.

Most men with trichomoniasis do not have signs or symptoms; however, some men may temporarily have an irritation inside the penis, mild discharge, or slight burning after urination or ejaculation.
Some women have signs or symptoms of infection which include a frothy, yellow-green vaginal discharge with a strong odor. The infection also may cause discomfort during intercourse and urination, as well as irritation and itching of the female genital area. In rare cases, lower abdominal pain can occur. Symptoms usually appear in women within 5 to 28 days of exposure.

The genital inflammation caused by trichomoniasis can increase a woman’s susceptibility to HIV infection if she is exposed to the virus. Having trichomoniasis may increase the chance that an HIV-infected woman passes HIV to her sex partner(s).

Genital Warts

Genital Warts
Genital human papillomavirus (HPV) is the most common sexually transmitted infection (STI). The virus infects the skin and mucous membranes. There are more than 40 HPV types that can infect the genital areas of men and women, including the skin of the penis, vulva (area outside the vagina), and anus, and the linings of the vagina, cervix, and rectum. You cannot see HPV. Most people who become infected with HPV do not even know they have it.

Most people with HPV do not develop symptoms or health problems. But sometimes, certain types of HPV can cause genital warts in men and women. Other HPV types can cause cervical cancer and other less common cancers, such as cancers of the vulva, vagina, anus, and penis. The types of HPV that can cause genital warts are not the same as the types that can cause cancer.
HPV types are often referred to as “low-risk” (wart-causing) or “high-risk” (cancer-causing), based on whether they put a person at risk for cancer. In 90% of cases, the body’s immune system clears the HPV infection naturally within two years. This is true of both high-risk and low-risk types.
Genital warts usually appear as small bumps or groups of bumps, usually in the genital area. They can be raised or flat, single or multiple, small or large, and sometimes cauliflower shaped. They can appear on the vulva, in or around the vagina or anus, on the cervix, and on the penis, scrotum, groin, or thigh. Warts may appear within weeks or months after sexual contact with an infected person. Or, they may not appear at all. If left untreated, genital warts may go away, remain unchanged, or increase in size or number. They will not turn into cancer.
Cervical cancer does not have symptoms until it is quite advanced. For this reason, it is important for women to get screened regularly for cervical cancer.
Other less common HPV-related cancers, such as cancers of the vulva, vagina, anus and penis, also may not have signs or symptoms until they are advanced.

Genital HPV is passed on through genital contact, most often during vaginal and anal sex. A person can have HPV even if years have passed since he or she had sex. Most infected persons do not realize they are infected or that they are passing the virus to a sex partner.
Very rarely, a pregnant woman with genital HPV can pass HPV to her baby during vaginal delivery. In these cases, the child may develop warts in the throat or voice box – a condition called recurrent respiratory papillomatosis (RRP).

HPV can cause normal cells on infected skin or mucous membranes to turn abnormal. Most of the time, you cannot see or feel these cell changes. In most cases, the body fights off HPV naturally and the infected cells then go back to normal.
Sometimes, low-risk types of HPV can cause visible changes that take the form of genital warts.
If a high-risk HPV infection is not cleared by the immune system, it can linger for many years and turn abnormal cells into cancer over time. About 10% of women with high-risk HPV on their cervix will develop long-lasting HPV infections that put them at risk for cervical cancer. Similarly, when high-risk HPV lingers and infects the cells of the penis, anus, vulva, or vagina, it can cause cancer in those areas. But these cancers are much less common than cervical cancer.

Safe Sex

Nobody has a body to die for. Safe sex is always better! It's fun, and you don't have to worry as much.
Safe sex means making sure you don't get anyone else's blood, semen, vaginal fluids, or breast milk in your body -- and protecting your partners too! Condoms, latex surgical gloves, and plastic wrap are the only ways to protect yourself and your partner from STDs and HIV, but they're not foolproof. You've got to use them correctly every time you have sex.
condoms
The best condoms for anal and vaginal intercourse are lubricated latex condoms. We do not recommend lambskin condoms because they don’t block HIV and STDs. If you're allergic to latex you can use polyurethane condoms. Using lubricant will make things go smoother and give you added protection. Lube is especially great for women the first time you have intercourse, or if you tend to get sore. But always use a water-based lube (such as KY Jelly, Astroglide, Aqua Lube, Wet, Foreplay, or Probe). Oil breaks latex. Don't use vaseline, hand creams or lotions as a lubricant. Also, treatments for yeast infections contain oil and will break latex. Oil is good for salads and cars, not for sex! You can buy water-based lube and condoms at the drugstore.
Always use a condom.
If you're going to suck your partner's dick (blowjob), put a condom on it first. Try non-lubricated or flavored condoms for this. Whatever you do, don't get semen (cum) in your mouth, because you could get an STD or HIV that way. If you have a sore throat or small cuts on your gums (say from brushing your teeth), there's a risk of HIV going from the semen into your blood stream.
If you're doing someone with a sex toy -- vegetable, dildo, vibrator, or whatever -- put a condom on that thing! Don't switch the toy from butthole to vagina, or from one person's body to another, until you put a new condom on it.
Some people think that putting on a condom is too much work when you're supposed to be having fun. But it's easy for condoms to be really fun and erotic. Be creative!
