Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts, ranging from activities done alone to acts with another person in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another or enhance the sex life of another, such as strategies to find or attract partners, or personal interactions between individuals. Sexual activity may follow sexual arousal.
Bondage, in the BDSM subculture, is the practice of consensually tying, binding, or restraining a partner for erotic, aesthetic, or somatosensory stimulation. A partner may be physically restrained in a variety of ways, including the use of rope, cuffs, bondage tape, or self-adhering bandage.
Sexual fetishism or erotic fetishism is a sexual fixation on a nonliving object or body part. The object of interest is called the fetish; the person who has a fetish for that object is a fetishist. A sexual fetish may be regarded as a mental disorder if it causes significant psychosocial distress for the person or has detrimental effects on important areas of their life. Sexual arousal from a particular body part can be further classified as partialism.
Asexuality is the lack of sexual attraction to others, or low or absent interest in or desire for sexual activity. It may be considered a sexual orientation or the lack thereof. It may also be categorized more widely, to include a broad spectrum of asexual sub-identities.
Autofellatio is a form of masturbation involving the oral stimulation of one's own penis. Only a limited number of males are physically capable of performing fellatio on themselves due to the flexibility required.
Self-bondage refers to the use of restraints on oneself for erotic pleasure. It is a form of erotic bondage which can be practiced alone.
Autoerotic fatalities are accidental deaths that occur during sexual self-stimulation when an apparatus, device or prop that is being employed to enhance pleasure causes the death. Researchers only apply the term to unintentional deaths resulting from solitary sexual activity, not suicide or acts with a partner. The incidence of autoerotic fatalities in Western countries is around 0.5 per million inhabitants each year.
A sexual fantasy or erotic fantasy is an autoerotic mental image or pattern of thought that stirs a person's sexuality and can create or enhance sexual arousal. A sexual fantasy can be created by the person's imagination or memory, and may be triggered autonomously or by external stimulation such as erotic literature or pornography, a physical object, or sexual attraction to another person. Anything that may give rise to sexual arousal may also produce a sexual fantasy, and sexual arousal may in turn give rise to fantasies.
Sexual stimulation is anything that leads to sexual arousal or orgasm. This thing can be physical or of other senses, and is known as a stimulus.
Hypoactive sexual desire disorder (HSDD), hyposexuality or inhibited sexual desire (ISD) is sometimes considered a sexual dysfunction, and is characterized as a lack or absence of sexual fantasies and desire for sexual activity, as judged by a clinician. For this to be regarded as a disorder, it must cause marked distress or interpersonal difficulties and not be better accounted for by another mental disorder, a drug, or some other medical condition. A person with ISD will not start, or respond to their partner's desire for, sexual activity. HSDD affects approximately 10% of all pre-menopausal women in the United States, or about 6 million women, 1.5% of men and an unstudied amount of gender non-conforming people.
Edging, sometimes also referred to as gooning or surfing, is a sexual technique whereby an orgasm is controlled. It is practiced alone or with a partner and involves the maintenance of a high level of sexual arousal for an extended period without reaching climax. Orgasm control involves either sex partner being in control of the other partner's orgasm, or a person delaying their own orgasm during sexual activity with a partner or through masturbation. Any method of sexual stimulation can be used to experience controlled orgasm.
Anal masturbation is an autoerotic practice in which a person masturbates by sexually stimulating their own anus and rectum. Common methods of anal masturbation include manual stimulation of the anal opening and the insertion of an object or objects. Items inserted may be sex toys such as anal beads, butt plugs, dildos, vibrators, or specially designed prostate massagers or enemas.
Erotic asphyxiation is the intentional restriction of oxygen to the brain for the purposes of sexual arousal. With a partner, the act often involves strangulation. The term autoerotic asphyxiation is used when the act is done by a person to themself. Colloquially, a person engaging in the activity is sometimes called a gasper. Erotic asphyxiation can lead to accidental death due to asphyxia.
Erotic humiliation or Sexual humiliation is a consensual psychological humiliation performed in order to produce erotic excitement or sexual arousal. This can be for either the person(s) being humiliated and demeaned or the person(s) humiliating, or both. It is sometimes performed before spectators, including through pornography and webcam modeling. It may be part of BDSM and other sexual roleplay, or accompanied by the sexual stimulation of the genitals of one or both parties in the activity.
Among the world's religions, views on masturbation vary widely. Some religions view it as a spiritually detrimental practice, some see it as not spiritually detrimental and others take a situational view. Among these latter religions, some view masturbation as allowable if used as a means towards sexual self-control, or as part of healthy self-exploration, but disallow it if it is done with motives they consider to be wrong, or as an addiction. For example, Christian denominations have different views on masturbation. Today, Roman Catholic, Eastern Orthodox, Oriental Orthodox and some Protestant Christians consider masturbation to be a sin. Many Protestant churches in Northern and Western Europe and some Protestant churches in Northern America and in Australia/New Zealand see masturbation as not a sin.
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 use of hands, everyday objects, sex toys, or more rarely, the mouth. Masturbation may also be performed with a sex partner, either masturbating together or watching the other partner masturbate.
The history of masturbation describes broad changes in society concerning the ethics, social attitudes, scientific study, and artistic depiction of masturbation over the history of sexuality.
The following outline is provided as an overview of and topical guide to human sexuality:
Autocunnilingus is a form of masturbation involving the oral stimulation of one's own vulva. Performing cunnilingus on oneself requires an unusually high degree of flexibility such as that of contortionists or double-jointed people.
This is a timeline of asexual history worldwide. The briefness of this timeline can be attributed to the fact that acceptance of asexuality as a sexual orientation and field of scientific research is still relatively new.
