Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure. Other forms of anal sex include anal fingering, the use of sex toys, anilingus, pegging, as well as electrostimulation and erotic torture such as figging. Although anal sex most commonly means penile–anal penetration, sources sometimes use anal intercourse to exclusively denote penile–anal penetration, and anal sex to denote any form of anal sexual activity, especially between pairings as opposed to anal masturbation.
Fellatio is an oral sex act involving a person stimulating the penis of another by using the mouth. Oral stimulation of the scrotum may also be termed fellatio, or colloquially as teabagging.
Sexual intercourse is sexual activity involving the insertion and thrusting of the male penis inside the female vagina for sexual pleasure, reproduction, or both. This is also known as vaginal intercourse or vaginal sex. Sexual penetration has been known by humans since the dawn of time, and has been an instinctive form of sexual behaviour and psychology among humans. Other forms of penetrative sexual intercourse include anal sex, oral sex, fingering and penetration by use of a dildo, and vibrators. These activities involve physical intimacy between two or more people and are usually used among humans solely for physical or emotional pleasure. They can contribute to human bonding.
Safe sex is sexual activity using methods or contraceptive devices to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. "Safe sex" is also sometimes referred to as safer sex or protected sex to indicate that some safe sex practices do not eliminate STI risks. It is also sometimes used colloquially to describe methods aimed at preventing pregnancy that may or may not also lower STI risks.
Fisting—also known as fist fucking (FF), handballing, and brachioproctic or brachiovaginal insertion—is a sexual activity that involves inserting one or more hands into the rectum or the vagina. Fisting may be performed on oneself (self-fisting) or performed on one person by another. People who engage in fisting are often called "fisters".
The handkerchief code is a system of color-coded cloth handkerchief or bandanas for non-verbally communicating one's interests in sexual activities and fetishes. The color of the handkerchief identifies a particular activity, and the pocket it is worn in identifies the wearer's preferred role in that activity. Wearing a handkerchief on the left side of the body typically indicates one is a "top" while wearing it on the right side of the body would indicate one is a "bottom". For example, a dark blue handkerchief indicates an interest in anal sex, and wearing it in the left pocket indicates a preference for being the penetrating partner. The code was first used in the 1970s in the United States, Canada, Australia, and Europe, by gay and bisexual men seeking casual sex or BDSM practitioners. Over time the colors and types of apparel in use have greatly proliferated.
A sex position is a positioning of the bodies that people use to engage in sexual intercourse or other sexual activities. Sexual acts are generally described by the positions the participants adopt in order to perform those acts. Though sexual intercourse generally involves penetration of the body of one person by another, sex positions commonly involve non-penetrative sexual activities.
The missionary position or man-on-top position is a sex position in which, generally, a woman lies on her back and spreads her legs and a man lies on top of her while they face each other and engage in vaginal intercourse. The position may also be used for other sexual activity, such as anal sex. It is commonly associated with heterosexual sexual activity, but is also used by same-sex couples. It may involve sexual penetration or non-penetrative sex, and its penile-vaginal aspect is an example of ventro-ventral (front-to-front) reproductive activity. Variations of the position allow varying degrees of clitoral stimulation, depth of penetration, participation on the part of the woman, and the likelihood and speed of orgasm.
Tribadism or tribbing, commonly known by its scissoring position, is a lesbian sexual practice involving vulva-to-vulva contact or rubbing the vulva against the partner's thigh, stomach, buttocks, arm, or other body parts, especially for stimulation of the clitoris. A variety of sex positions are practiced, including the missionary position.
Sexual penetration is the insertion of a body part or other object into a body orifice, such as the mouth, vagina or anus, as part of human sexual activity or sexual behavior in non-human animals.
Frot or frotting is a gay sexual practice that usually involves direct penis-to-penis contact. The term was popularized by gay male activists who disparaged the practice of anal sex, but has since evolved to encompass a variety of preferences for the act, which may or may not imply particular attitudes towards other sexual activities. This can also be used as some type of foreplay.
Men who have sex with men (MSM) refers to all men who engage in sexual activity with other men, regardless of their sexual orientation or sexual identity. The term was created by epidemiologists in the 1990s, to better study and communicate the spread of sexually transmitted infections such as HIV/AIDS between all sexually active males, not strictly those identifying as gay, bisexual, pansexual or various other sexualities, but also for example male prostitutes. The term is often used in medical literature and social research to describe such men as a group. It does not describe any specific kind of sexual activity, and which activities are covered by the term depends on context. An alternative term, males who have sex with males is sometimes considered more accurate in cases where those described may not be legal adults.
Oral sex, sometimes referred to as oral intercourse, is sexual activity involving the stimulation of the genitalia of a person by another person using the mouth. Cunnilingus is oral sex performed on the vulva while fellatio is oral sex performed on the penis. Anilingus, another form of oral sex, is oral stimulation of the anus.
A strap-on dildo is a dildo designed to be worn, usually with a harness, during sexual activity. Harnesses and dildos are made in a wide variety of styles, with variations in how the harness fits the wearer, how the dildo attaches to the harness, as well as various features intended to facilitate stimulation of the wearer or a sexual partner. Strap-on dildos are most frequently used by lesbian women, but can be used by people of any gender or sexuality.
Homosexuality in ancient Rome often differs markedly from the contemporary West. Latin lacks words that would precisely translate "homosexual" and "heterosexual". The primary dichotomy of ancient Roman sexuality was active / dominant / masculine and passive / submissive / feminine. Roman society was patriarchal, and the freeborn male citizen possessed political liberty (libertas) and the right to rule both himself and his household (familia). "Virtue" (virtus) was seen as an active quality through which a man (vir) defined himself. The conquest mentality and "cult of virility" shaped same-sex relations. Roman men were free to enjoy sex with other males without a perceived loss of masculinity or social status as long as they took the dominant or penetrative role. Acceptable male partners were slaves and former slaves, prostitutes, and entertainers, whose lifestyle placed them in the nebulous social realm of infamia, so they were excluded from the normal protections accorded to a citizen even if they were technically free. Freeborn male minors were off limits at certain periods in Rome.
Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration. It generally excludes the penetrative aspects of vaginal, anal, or oral sex, but includes various forms of sexual and non-sexual activity, such as frottage, manual sex, mutual masturbation, kissing, or cuddling. Some forms of non-penetrative sex, particularly when termed outercourse, include penetrative aspects, such as penetration that may result from forms of fingering or oral sex.
Pegging generally refers to a sexual activity that involves a woman wearing a strap-on dildo while performing anal penetration on a man, although the term can also be used to describe it regardless of gender roles.
In American slang, baseball metaphors for sex are often used as euphemisms for the degree of physical intimacy achieved in sexual encounters or relationships. In the metaphor, first prevalent in the aftermath of World War II, sexual activities are described as if they are actions in a game of baseball. Baseball has also served as the context for metaphors about sexual roles and identity.
Sexual activities involving men who have sex with men (MSM), regardless of their sexual orientation or sexual identity, can include anal sex, non-penetrative sex, and oral sex. Evidence shows that sex between men is significantly underreported in surveys.
Gender roles in non-heterosexual communities are a topic of much debate; some people believe traditional, heterosexual gender roles are often erroneously enforced on non-heterosexual relationships by means of heteronormative culture and attitudes towards these non-conformative relationships.
