Sapphist

A lesbian is a female homosexual: a female who experiences romantic love or sexual attraction to other females. The term lesbian is also used to express sexual identity or sexual behavior regardless of sexual orientation, or as an adjective to characterize or associate nouns with female homosexuality or same-sex attraction.

The concept of "lesbian", to differentiate women with a shared sexual orientation, is a 20th-century construct. Throughout history, women have not had the same freedom or independence to pursue homosexual relationships as men, but neither have they met the same harsh punishment as homosexual men in some societies. Instead, lesbian relationships have often been regarded as harmless and incomparable to heterosexual ones unless the participants attempted to assert privileges traditionally enjoyed by men. As a result, little in history was documented to give an accurate description of how female homosexuality is expressed. When early sexologists in the late 19th century began to categorize and describe homosexual behavior, hampered by a lack of knowledge about homosexuality or women's sexuality, they distinguished lesbians as women who did not adhere to female gender roles and incorrectly designated them mentally ill—a designation which has been reversed in the global scientific community.

Women in homosexual relationships responded to this designation either by hiding their personal lives or accepting the label of outcast and creating a subculture and identity that developed in Europe and the United States. Following World War II, during a period of social repression when governments actively persecuted homosexuals, women developed networks to socialize with and educate each other. Greater economic and social freedom allowed them gradually to be able to determine how they could form relationships and families. With second wave feminism and growth of scholarship in women's history and sexuality in the 20th century, the definition of lesbian broadened, sparking a debate about sexual desire as the major component to define what a lesbian is. Some women who engage in same-sex sexual activity may reject not only identifying as lesbians but as bisexual as well, while other women's self-identification as lesbian may not align with their sexual orientation or sexual behavior; sexual identity is not necessarily the same as one's sexual orientation or sexual behavior, due to various reasons, such as the fear of identifying their sexual orientation in a homophobic setting.
