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.
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. 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 individuals and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding.
Sexual abstinence or sexual restraint is the practice of refraining from some or all aspects of sexual activity for medical, psychological, legal, social, philosophical, moral, religious or other reasons. Sexual abstinence is distinct from asexuality, which is a sexual orientation where people feel little or no sexual attraction. Celibacy is sexual abstinence generally motivated by factors such as an individual's personal or religious beliefs. Sexual abstinence before marriage is required in some societies by social norms, or by law in some countries. It is a part of chastity.
Group sex is sexual activity involving more than two people. Participants in group sex can be of any sexual orientation or gender. Any form of sexual activity can be adopted to involve more than two participants, but some forms have their own names.
Foreplay is a set of emotionally and physically intimate acts between one or more people meant to create sexual arousal and desire for sexual activity. 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, removing clothes, oral sex, manual sex, sexual games, and role playing.
The Kinsey scale, also called the Heterosexual–Homosexual Rating Scale, is used in research to describe a person's sexual orientation based on one's experience or response at a given time. The scale typically ranges from 0, meaning exclusively heterosexual, to a 6, meaning exclusively homosexual. In both the male and female volumes of the Kinsey Reports, an additional grade, listed as "X", indicated "no socio-sexual contacts or reactions" (asexuality). The reports were first published in Sexual Behavior in the Human Male (1948) by Alfred Kinsey, Wardell Pomeroy, and others, and were also prominent in the complementary work Sexual Behavior in the Human Female (1953).
The missionary position or man-on-top position is a sex position in which, generally, a woman lies on her back 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.
Sexual desire is an emotion and motivational state characterized by an interest in sexual objects or activities, or by a drive to seek out sexual objects or to engage in sexual activities. It is an aspect of sexuality, which varies significantly from one person to another and also fluctuates depending on circumstances.
The Masters and Johnson research team, composed of William H. Masters and Virginia E. Johnson, pioneered research into the nature of human sexual response and the diagnosis and treatment of sexual disorders and dysfunctions from 1957 until the 1990s.
The social construction of human sexuality and sexual behavior—along with its taboos, regulation, and social and political impact—has had a profound effect on the various cultures of the world since prehistoric times.
Sexual ethics is a branch of philosophy that considers the ethics or morality or otherwise in sexual behavior. Sexual ethics seeks to understand, evaluate and critique interpersonal relationships and sexual activities from a social, cultural, and philosophical perspective. Some people consider aspects of human sexuality, such as gender identification and sexual orientation, as well as consent, sexual relations and procreation, as giving rise to issues of sexual ethics.
A sexless marriage is a marital union in which little or no sexual activity occurs between the two spouses. The US National Health and Social Life Survey in 1992 found that 2% of married respondents aged 18 to 59 reported no sexual intimacy in the past year. Comparatively 92% of married respondents aged 65 to 80 reported no sexual intimacy in the past year. The definition of a non-sexual marriage is often broadened to include those where sexual intimacy occurs fewer than ten times per year, in which case 20 percent of the couples in the National Health and Social Life Survey would be in the category. Other studies show that 10% or less of the married population below age 50 have not had sex in the past year. In addition less than 20% report having sex a few times per year, or even monthly, under the age 40.
Adolescent sexuality is a stage of human development in which adolescents experience and explore sexual feelings. Interest in sexuality intensifies during the onset of puberty, and sexuality is often a vital aspect of teenagers' lives. Sexual interest may be expressed in a number of ways, such as flirting, kissing, masturbation, or having sex with a partner. Sexual interest among adolescents, as among adults, can vary greatly, and is influenced by cultural norms and mores, sex education, as well as comprehensive sexuality education provided, sexual orientation, and social controls such as age-of-consent laws.
The sexuality of US adolescents includes their feelings, behaviors and development, and the place adolescent sexuality has in American society, including the response of the government, educators, parents, and other interested groups.
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.
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. The stimulation may involve the 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.
Sexual activities involving women who have sex with women (WSW), regardless of their sexual orientation or sexual identity, can include oral sex, manual sex, or tribadism.
Human sexuality is the way people experience and express themselves sexually. This involves biological, psychological, physical, erotic, emotional, social, or spiritual feelings and behaviors. Because it is a broad term, which has varied with historical contexts over time, it lacks a precise definition. The biological and physical aspects of sexuality largely concern the human reproductive functions, including the human sexual response cycle.
Sexual desire discrepancy (SDD) is the difference between one's desired frequency of sexual intercourse and the actual frequency of sexual intercourse within a relationship. Among couples seeking sex therapy, problems of sexual desire are the most commonly reported dysfunctions, yet have historically been the most difficult to treat successfully. Sexual satisfaction in a relationship has a direct relationship with overall relationship satisfaction and relationship well-being. Sexual desire and sexual frequency do not stem from the same domains, sexual desire characterizes an underlying aspect of sexual motivation and is associated with romantic feelings while actual sexual activity and intercourse is associated with the development and advancement of a given relationship. Thus together, sexual desire and sexual frequency can successfully predict the stability of a relationship. While higher individual sexual desire discrepancies among married individuals may undermine overall relationship well-being, higher SDD scores for females may be beneficial for romantic relationships, because those females have high levels of passionate love and attachment to their partner. Studies suggest that women with higher levels of desire relative to that of their partners' may experience fewer relationship adjustment problems than women with lower levels of desire relative to their partners'. Empirical evidence has shown that sexual desire is a factor that heavily influences couple satisfaction and relationship continuity which has been one of the main reasons for the interest in this research domain of human sexuality.
Sexual arousal describes the physiological and psychological responses in preparation for sexual intercourse or when exposed to sexual stimuli. A number of physiological responses occur in the body and mind as preparation for sexual intercourse, and continue during intercourse. Male arousal will lead to an erection, and in female arousal, the body's response is engorged sexual tissues such as nipples, vulva, clitoris, vaginal walls, and vaginal lubrication.
