Human sexuality

Human sexuality is the way people experience and express themselves sexually.[1][2] This involves biological, psychological, physical, erotic, emotional, social, or spiritual feelings and behaviors.[3][4] Because it is a broad term, which has varied with historical contexts over time, it lacks a precise definition.[4] The biological and physical aspects of sexuality largely concern the human reproductive functions, including the human sexual response cycle.[3][4]

This article is about human sexual anatomy, sexuality and perceptions. For information specifically about sexual activities, see Human sexual activity. For the book, see Human Sexuality (book).

Someone's sexual orientation is their pattern of sexual interest in the opposite and/or same sex.[5] Physical and emotional aspects of sexuality include bonds between individuals that are expressed through profound feelings or physical manifestations of love, trust, and care. Social aspects deal with the effects of human society on one's sexuality, while spirituality concerns an individual's spiritual connection with others. Sexuality also affects and is affected by cultural, political, legal, philosophical, moral, ethical, and religious aspects of life.[3][4]


Interest in sexual activity normally increases when an individual reaches puberty.[6] Although no single theory on the cause of sexual orientation has yet gained widespread support, there is considerably more evidence supporting nonsocial causes of sexual orientation than social ones, especially for males. Hypothesized social causes are supported by only weak evidence, distorted by numerous confounding factors.[7] This is further supported by cross-cultural evidence, because cultures that are tolerant of homosexuality do not have significantly higher rates of it.[8][9]


Evolutionary perspectives on human coupling, reproduction and reproduction strategies, and social learning theory provide further views of sexuality.[10] Sociocultural aspects of sexuality include historical developments and religious beliefs. Some cultures have been described as sexually repressive. The study of sexuality also includes human identity within social groups, sexually transmitted infections (STIs), and birth control methods.

Psychological aspects[edit]

As one form of behavior, the psychological aspects of sexual expression have been studied in the context of emotional involvement, gender identity, intersubjective intimacy, and Darwinian reproductive efficacy. Sexuality in humans generates profound emotional and psychological responses. Some theorists identify sexuality as the central source of human personality.[68] Psychological studies of sexuality focus on psychological influences that affect sexual behavior and experiences.[15] Early psychological analyses were carried out by Sigmund Freud, who believed in a psychoanalytic approach. He also proposed the concepts of psychosexual development and the Oedipus complex, among other theories.[69]


Gender identity is a person's sense of their own gender, whether male, female, or non-binary.[70] Gender identity can correlate with assigned sex at birth or can differ from it.[71] All societies have a set of gender categories that can serve as the basis of the formation of a person's social identity in relation to other members of society.[72]


Sexual behavior and intimate relationships are strongly influenced by a person's sexual orientation.[73]


Sexual orientation is an enduring pattern of romantic or sexual attraction (or a combination of these) to persons of the opposite sex, same sex, or both sexes.[73] Heterosexual people are romantically/sexually attracted to the members of the opposite sex, gay and lesbian people are romantically/sexually attracted to people of the same sex, and those who are bisexual are romantically/sexually attracted to both sexes.[5]


The idea that homosexuality results from reversed gender roles is reinforced by the media's portrayal of gay men as feminine and lesbians as masculine.[74] However, a person's conformity or non-conformity to gender stereotypes does not always predict sexual orientation. Society believes that if a man is masculine, he is heterosexual, and if a man is feminine, he is homosexual. There is no strong evidence that a homosexual or bisexual orientation must be associated with atypical gender roles. By the early 21st century, homosexuality was no longer considered to be a pathology. Theories have linked many factors, including genetic, anatomical, birth order, and hormones in the prenatal environment, to homosexuality.[74]


Other than the need to procreate, there are many other reasons people have sex. According to one study conducted on college students (Meston & Buss, 2007), the four main reasons for sexual activities are physical attraction, as a means to an end, to increase emotional connection, and to alleviate insecurity.[75]

the use of indirect behavior to convey romantic or sexual interest. It can involve verbal or non-verbal cues, such as sexual comments, body language, gazing, or close to another, but non-verbal flirting is more common.[148] Flirting is a socially accepted way of attracting someone. There are different types of flirting, and most people usually have one way of flirting that makes them most comfortable. When flirting, people can be polite, playful, physical, etc. Sometimes it is difficult to know whether or not the person is interested.[149] Non-verbal flirting allows people to test another's interest without fear of direct rejection.[148] Flirting styles vary according to culture. Different cultures have different social etiquette. For example, length of eye contact, or how closely one stands by someone.[150]

Flirting

the process whereby one person deliberately entices another to engage in sexual behavior.[151] This behavior is one that the person you are seducing would not usually do, unless sexually aroused. Seduction can be seen as both a positive and a negative. Since the word seduction has a Latin meaning, which is "to lead astray" it can be viewed negatively.[152]

Sexual reproduction is part of the biological nature of humans, so it may be surprising how much sexuality varies cross-culturally. Indeed, societies vary considerably in the degree to which they encourage, discourage, or even appear to fear heterosexual sex at different life stages and in varying circumstances.
