What is this site about? Mostly… lesbians

A lesbian is a woman who is romantically and sexually attracted only to other women. Lesbian sex can be made with sex toys or with fingers and lips only.
Women who are attracted to both women and men are more often referred to as bisexual. An individual’s self-identification might not correspond with her behavior, and may be expressed with either, both, or neither of these words.

Lesbian sexual practices are many and sundry. As with most interpersonal behaviour any physical expression of intimacy depends on the context of the relationship along with social, cultural and other influences.
The word lesbian dates back at least to 1732 and lesbianism appears in the 1870 Oxford English Dictionary meaning sexual orientation rather than a reference to Sappho and inhabitants of Lesbos. Lesbian as an adjective is in the 1890 Oxford English Dictionary and as a noun by 1925. Until the early twentieth century lesbian was interchangeable with Sapphist.

Sex educator and feminist Shere Hite’s research (while subject to methodological limitations) showed “sex as we define it is a cultural institution, not a biological one,” that most women need clitoral or exterior stimulation for orgasm which can be “easy and strong, given the right stimulation” and most women reach orgasm more easily by masturbation. Hite noted one of her female research subjects had written, “Sex with a woman includes: touching, kissing, smiling, looking serious, embracing, talking, digital intercourse, caressing, looking, cunnilingus, undressing, remembering later, making sounds, sometimes gently biting, sometimes crying, and breathing and sighing together.” Other notable forms of intimate expression between lesbians can include gestures such as tribadism, use of a dildo and more rarely, anilingus.
