Catharine MacKinnon, Andrea Dworkin, Robin Morgan and Dorchen Leidholdt, to put pornography at the center of a feminist explanation of women's oppression. This period of intense debate and acrimony between sex-positive and anti-pornography feminists during the early 1980s is often referred to as the "Feminist Sex Wars". Other sex-positive feminists became involved, not in opposition to other feminists, but in direct response to what they saw as patriarchal control of sexuality. Some authors who have advocated sex-positive feminism include Erika Lust, Ellen Willis, Susie Bright, Patrick Califia, Gayle Rubin, Carol Queen, Avedon Carol, Tristan Taormino, Diana Cage, Nina Hartley, and Betty Dodson.

Pro-sex feminism endeavors to cultivate sexuality as a site of political resistance. By using the "pleasure" factor in their favor, a significant contribution to the contemporary queer theory and politics has been made by using sexual and feminist "empowerment."
