Lesbianism is sexual activity or attraction between women. Female homosexuals are often called lesbians (after the Greek island of Lesbos, home of Sappho). Homosexuality normally focuses on men more than in women, but the problem is not minor. Women who are attracted to both women and men are called bisexuals. The word "lesbian" was first used in the late 16th century. Lesbianism is also called sapphism or female homosexuality. (Sappho penned love sonnets to women. She lived from 610-580 B.C.)
