Heterosexuality is romantic attraction, sexual attraction or sexual behavior between persons of the opposite sex or gender. As a sexual orientation, heterosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" to persons 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 orientation is an enduring pattern of romantic or sexual attraction to persons of the opposite sex or gender, the same sex or gender, or to both sexes or more than one gender. These attractions are generally subsumed under heterosexuality, homosexuality, and bisexuality, while asexuality is sometimes identified as the fourth category.
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).
Pansexuality is sexual, romantic, or emotional attraction towards people regardless of their sex or gender identity. Pansexual people may refer to themselves as gender-blind, asserting that gender and sex are not determining factors in their romantic or sexual attraction to others.
Sexual attraction is attraction on the basis of sexual desire or the quality of arousing such interest. Sexual attractiveness or sex appeal is an individual's ability to attract other people sexually, and is a factor in sexual selection or mate choice. The attraction can be to the physical or other qualities or traits of a person, or to such qualities in the context where they appear. The attraction may be to a person's aesthetics or movements or to their voice or smell, among other things. The attraction may be enhanced by a person's adornments, clothing, perfume or style. It can be influenced by individual genetic, psychological, or cultural factors, or to other, more amorphous qualities. Sexual attraction is also a response to another person that depends on a combination of the person possessing the traits and on the criteria of the person who is attracted.
In human sexuality, a threesome is commonly understood as "a sexual interaction between three people whereby at least one engages in physical sexual behaviour with both the other individuals". Though threesome most commonly refers to sexual activity involving three participants, it is also sometimes used to apply to a long-term domestic relationship, such as polyamory or a ménage à trois.
Sexual identity is how one thinks of oneself in terms of to whom one is romantically and/or sexually attracted. Sexual identity may also refer to sexual orientation identity, which is when people identify or dis-identify with a sexual orientation or choose not to identify with a sexual orientation. Sexual identity and sexual behavior are closely related to sexual orientation, but they are distinguished, with identity referring to an individual's conception of themselves, behavior referring to actual sexual acts performed by the individual, and sexual orientation referring to romantic or sexual attractions toward persons of the opposite sex or gender, the same sex or gender, to both sexes or more than one gender, or to no one.
Plant reproductive morphology is the study of the physical form and structure of those parts of plants directly or indirectly concerned with sexual reproduction.
Obtaining precise numbers on the demographics of sexual orientation is difficult for a variety of reasons, including the nature of the research questions.
Lesbian, gay, bisexual, and transgender (LGBT) persons in the Central African Republic face legal and social challenges not experienced by non-LGBT residents. Both male and female same-sex sexual activity is legal in the Central African Republic but LGBT persons face stigmatization among the broader population. The Central African Republic was one of the few African states that signed a "joint statement on ending acts of violence and related human rights violations based on sexual orientation and gender identity" at the United Nations, condemning violence and discrimination against LGBT people.
Homosexuality is romantic attraction, sexual 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" to people of the same 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."
Lesbian, gay, bisexual, and transgender (LGBT) persons in Comoros face legal challenges not experienced by non-LGBT residents. LGBT persons are regularly prosecuted by the government and additionally face stigmatization among the broader population.
Lesbian sexual practices are sexual activities involving women who have sex with women, regardless of their sexual orientation. A woman who has sex with another woman may identify as a lesbian if she is sexually attracted to women, or bisexual if she is not exclusively sexually attracted to women, or dispense with sexual identification altogether. The term may also be applied to a heterosexual or asexual woman who is unsure of or is exploring her sexuality.
Human sexuality is the way people experience and express themselves sexually. This involves biological, erotic, physical, 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.
Bisexuality is romantic attraction, sexual attraction, or sexual behavior toward both males and females, or to more than one gender. It may also be defined to include romantic or sexual attraction to people regardless of their sex or gender identity, which is also known as pansexuality.
Lesbian, gay, bisexual, and transgender (LGBT) persons in Togo face legal challenges not experienced by non-LGBT residents. Both male and female same-sex sexual activity is illegal in Togo.
A trans woman is a woman who was assigned male at birth. Trans women have a female gender identity, may experience gender dysphoria, and may transition; this process commonly includes hormone replacement therapy and sometimes sex reassignment surgery, which can bring relief and resolve feelings of gender dysphoria. Trans women may be heterosexual, bisexual, homosexual, asexual, or identify with other terms.
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. Mental stimuli and physical stimuli such as touch, and the internal fluctuation of hormones, can influence sexual arousal.
The history of bisexuality concerns the history of the bisexual sexual orientation. Ancient and medieval history of bisexuality, when the term did not exist as such, consists of anecdotes of sexual behaviour and relationships between people of the same and different sexes. A modern definition of bisexuality began to take shape in the mid-nineteenth century within three interconnected domains of knowledge: biology, psychology and sexuality. In modern Western culture, the term bisexual was first defined in a binary approach as a person with romantic or sexual attraction to both men and women. The term bisexual is defined later in the twentieth century as a person who is sexually and/or romantically attracted to both males and females, or as a person who is sexually and/or romantically attracted to people regardless of sex or gender identity, which is sometimes termed pansexuality.
