What is sexual orientation?

Sexual orientation refers to an enduring pattern of emotional, romantic, and/or sexual attractions to men, women, or both sexes. Sexual orientation 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. Research over several decades has demonstrated that sexual orientation ranges along a continuum, from exclusive attraction to the other sex to exclusive attraction to the same sex. However, sexual orientation is usually discussed in terms of three categories: heterosexual (having emotional, romantic, or sexual attractions to members of the other sex), gay/lesbian (having emotional, romantic, or sexual attractions to members of one’s own sex), and bisexual (having emotional, romantic, or sexual attractions to both men and women). This range of behaviors and attractions has been described in various cultures and nations throughout the world. Many cultures use identity labels to describe people who express these attractions. In the United States the most frequent labels are lesbians (women attracted to women), gay men (men attracted to men), and bisexual people (men or women attracted to both sexes). However, some people may use different labels or none at all.

Sexual orientation is distinct from other components of sex and gender, including biological sex (the anatomical, physiological, and genetic characteristics associated with being male or female), gender identity (the psychological sense of being male or female),* and social gender role (the cultural norms that define feminine and masculine behavior).

Sexual orientation is commonly discussed as if it were solely a characteristic of an individual, like biological sex, gender identity, or age. This perspective is incomplete because sexual orientation is defined in terms of relationships with others. People express their sexual orientation through behaviors with others, including such simple actions as holding hands or kissing. Thus, sexual orientation is closely tied to the intimate personal relationships that meet deeply felt needs for love, attachment, and intimacy. In addition to sexual behaviors, these bonds include nonsexual physical affection between partners, shared goals and values, mutual support, and ongoing commitment. Therefore, sexual orientation is not merely a personal characteristic within an individual. Rather, one’s sexual orientation defines the group of people in which one is likely to find the satisfying and fulfilling romantic relationships that are an essential component of personal identity for many people.

How do people know if they are lesbian, gay, or bisexual?

According to current scientific and professional understanding, the core attractions that form the basis for adult sexual orientation typically emerge between middle childhood and early adolescence. These patterns of emotional, romantic, and sexual attraction may arise without any prior sexual experience. People can be celibate and still know their sexual orientation-–be it lesbian, gay, bisexual, or heterosexual.

Different lesbian, gay, and bisexual people have very different experiences regarding their sexual orientation. Some people know that they are lesbian, gay, or bisexual for a long time before they actually pursue relationships with other people. Some people engage in sexual activity (with same-sex and/or othersex partners) before assigning a clear label to their sexual orientation. Prejudice and discrimination make it difficult for many people to come to terms with their sexual orientation identities, so claiming a lesbian, gay, or bisexual identity may be a slow process.
