The power of compulsory heterosexuality regulates the sexuality of adolescent lesbians as strongly as it does their heterosexual peers. Marked with a sexual(ized)identity, young Southern lesbians in this life history study made claim to moral high ground by consistently identifying with the hegemonic "good girl" construct and by participating in the naming of women whose sexual behavior demonstrated a disregard for the "rules." The good girl/bad girl, the virgin/slut binaries, played significant roles in their identity claims, in their relationships, and in their choices of friendships. Personal self-control ("just kissing") is seen by these young women as admirable and "sluts" are seen as dangerous women who harm others and themselves. This article explores the marking of "sluts" and "too experienced" women in the life stories of White Southern adolescent lesbians and the continued social controls imposed on adolescent female sexuality through the devaluing of women's sexual agency.
