Homosexuality is the romantic or sexual attraction to the same sex. People with a homosexual orientation can express their sexuality in a variety of ways, and may or may not express it in their behaviors.<ref name=APAHelp>{{cite web|url=http://www.apahelpcenter.org/articles/article.php?id=31 |title=Psychology Help Center |publisher=Apahelpcenter.org |access-date=30 June 2013 |url-status=dead |archive-url=https://web.archive.org/web/20070928051520/http://www.apahelpcenter.org/articles/article.php?id=31 |archive-date=28 September 2007 |df=dmy-all }}</ref> Research indicates that many gay men and lesbians want, and succeed in having, committed and durable relationships. For example, survey data indicate that between 40% and 60% of gay men and between 45% and 80% of lesbians are currently involved in a romantic relationship.<ref name=WhatIsNature>[http://www.apa.org/topics/lgbt/orientation.aspx#accordion1_content_11 What is the nature of same-sex relationships?] {{Webarchive|url=https://web.archive.org/web/20190120024548/https://www.apa.org/topics/lgbt/orientation.aspx#accordion1_content_11 |date=20 January 2019 }} American Psychological Association, Retrieved 25 December 2014</ref>

It is possible for a person whose sexual identity is mainly heterosexual to engage in sexual acts with people of the same sex. Gay and lesbian people who pretend to be heterosexual are often referred to as being [[closeted]] (hiding their sexuality in "the closet"). "Closet case" is a derogatory term used to refer to people who hide their sexuality. Making that orientation public can be called "[[coming out of the closet]]" in the case of voluntary disclosure or "[[outing]]" in the case of disclosure by others against the subject's wishes (or without their knowledge). Among some communities (called "men on the DL" or "[[Down-low (sexual slang)|down-low]]"), same-sex sexual behavior is sometimes viewed as solely for physical pleasure. [[Men who have sex with men]], as well as [[women who have sex with women]], or men on the "down-low" may engage in sex acts with members of the same sex while continuing sexual and romantic relationships with the opposite sex.

People who engage exclusively in same-sex sexual practices may not identify themselves as gay or lesbian. In sex-segregated environments, individuals may seek relationships with others of their own gender (known as [[situational homosexuality]]). In other cases, some people may experiment or explore their sexuality with same (or different) sex sexual activity before defining their [[sexual identity]]. Despite stereotypes and common misconceptions, there are no forms of sexual acts exclusive to same-sex sexual behavior that cannot also be found in opposite-sex sexual behavior, except those involving the meeting of the genitalia between same-sex partners&nbsp;– [[tribadism]] (generally [[vulva]]-to-vulva rubbing) and [[frot]] (generally [[Human penis|penis]]-to-penis rubbing).
