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.
Heterosexuality is romantic attraction, sexual attraction or sexual behavior between people of the opposite sex or gender. As a sexual orientation, heterosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" to people of the opposite sex. It "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions." Someone who is heterosexual is commonly referred to as straight.
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 a sexual activity typically 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.

Swinging, earlier commonly known as wife-swapping, is a sexual activity in which both singles and partners in a committed relationship sexually engage with others for recreational purposes. Swinging is a form of non-monogamy. People may choose a swinging lifestyle for a variety of reasons. Practitioners cite an increased quality and quantity of sex. Some people may engage in swinging to add variety into their otherwise conventional sex lives or due to their curiosity. Some couples see swinging as a healthy outlet and means to strengthen their relationship. The term "wife swapping" was introduced by the media in the United States during the 1950s to describe this emerging phenomenon. Swinging, or its wider discussion and practice, is regarded by some as arising from the freer attitudes to sexual activity after the sexual revolution of the 1960s, the invention and availability of the contraceptive pill, and the emergence of treatments for many of the sexually transmitted infections that were known at that time. The adoption of safe sex practices became more common in the late 1980s. It is also a recurring theme in pornography.
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.
Infidelity is a violation of a couple's emotional or sexual exclusivity that commonly results in feelings of anger, sexual jealousy, and rivalry.
Open marriage is a form of non-monogamy in which the partners of a dyadic marriage agree that each may engage in extramarital sexual or romantic relationships, without this being regarded by them as infidelity, and consider or establish an open relationship despite the implied monogamy of marriage. There are variant forms of open marriage such as swinging and polyamory, each with the partners having varying levels of input into their spouse's activities.
Hindu views of homosexuality and LGBTQ issues more generally are diverse, and different Hindu groups have distinct views. Hinduism describes a third gender that is equal to other genders and documentation of the third gender are found in ancient Hindu and Buddhist medical texts. The Kamasutra mentions Hijras and relations with them, and there are several Hindu temples which have carvings that depict both men and women engaging in sexual acts with Hijras. There are numerous cases of Hindu deities and figures that had physically transformed to different genders.
A gang bang is a sexual activity in which one person is the central focus of the sexual activity of several people, usually more than three, sequentially or simultaneously. The term generally refers to a woman being the focus; one man with multiple women can be referred to as a "reverse gang bang". The term has become associated with the porn industry and usually describes a staged event whereby a woman has sex with several men in direct succession. Bukkake is a type of gang bang, originating in Japan, that focuses on the central person being ejaculated upon by male participants.
Homosexuality is sexual attraction, romantic attraction, or sexual behavior between members of the same sex or gender. As a sexual orientation, homosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" exclusively to people of the same sex or gender.

Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration, but some forms, particularly when termed outercourse, include penetrative aspects, that may result from forms of fingering or oral sex. 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 hugging.
Casual dating or a casual relationship is a physical and emotional relationship between two people who may have casual sex or a near-sexual relationship while staying loyal to each other without necessarily demanding or expecting the additional commitments of a more formal romantic relationship. Motives for casual relationships vary. There are significant gender and cultural differences in acceptance of and breadth of casual relationships, as well as in regrets about action/inaction in those relationships.
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.
A mixed-orientation marriage is a marriage between partners of differing sexual orientations. The broader term is mixed-orientation relationship, sometimes shortened to MOR or MORE.
