Sexual acts

Sex, more formally known as sexual intercourse, coitus, or copulation, is an intimate social activity typically involving the insertion of the erect male penis inside the female vagina and followed by thrusting motions for erotic pleasure, biological reproduction, or both. This specific type of sex is also known as vaginal intercourse. However, other forms of penetrative sexual intercourse also exist, including anal sex, oral sex, fingering and penetration by use of a dildo, and vibrators. The desire for these activities is grounded in natural human instinct and they involve physical intimacy between two or more people, usually enacted by humans solely for physical-emotional pleasure, sometimes contributing to human bonding.

Masturbation is a form of autoeroticism in which a person sexually stimulates their own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. Stimulation may involve the use of hands, everyday objects, sex toys, or more rarely, the mouth (autofellatio and autocunnilingus). Masturbation may also be performed with a sex partner, either masturbating together or watching the other partner masturbate, known as "mutual masturbation".

Orgasm (from Greek , ; "excitement, swelling"), sexual climax, or simply climax, is the sudden release of accumulated sexual excitement during the sexual response cycle, characterized by intense sexual pleasure resulting in rhythmic, involuntary muscular contractions in the pelvic region. Orgasms are controlled by the involuntary or autonomic nervous system and are experienced by both males and females; the body's response includes muscular spasms (in multiple areas), a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm (known as the resoluti

Fellatio (also known as fellation, and in slang as blowjob, BJ, giving head, or sucking off) is an oral sex act consisting of the stimulation of a penis by using the mouth. Oral stimulation of the scrotum may also be termed fellatio, or colloquially as teabagging.

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.

Cunnilingus is an oral sex act consisting of the stimulation of a vulva by using the tongue and lips. The clitoris is the most sexually sensitive part of the vulva, and its stimulation may result in a woman becoming sexually aroused or achieving orgasm.

BDSM is a variety of often erotic practices or roleplaying involving bondage, discipline, dominance and submission, sadomasochism, and other related interpersonal dynamics. Given the wide range of practices, some of which may be engaged in by people who do not consider themselves to be practising BDSM, inclusion in the BDSM community or subculture often is said to depend on self-identification and shared experience.

Although foreplay is typically understood as physical sexual activity, nonphysical activities, such as mental or verbal acts, may in some contexts be foreplay. This is typically the reason why foreplay tends to be an ambiguous term and means different things to different people. It can consist of various sexual practices such as kissing, sexual touching,

Fisting (also known as fist fucking (FF) and handballing) is a sexual activity that involves inserting one or more hands into the rectum (anal fisting) or the vagina (vaginal fisting).

Urolagnia, also known as urophilia, is a paraphilia in which sexual excitement is associated with urine or urination.

A hickey, also known as love bite, is a bruise or bruise-like mark caused by sucking or biting the skin of a person, usually their neck. While biting may be part of giving a hickey, sucking is sufficient to burst small superficial blood vessels under the skin to produce bruising. A hickey is sometimes used to mark someone as being the target of a partner's romantic affection or as belonging to them.

In many traditions and statutes of civil or religious law, the definition usually refers to penile–vaginal penetration (i.e., heterosexual), and some religious doctrines hold an additional requirement prohibiting contraception. In this sense, "a marriage is consummated only if the conjugal act performed deposits semen in the vagina."
