Yes Means Yes: Visions of Female Sexual Power and a World Without Rape is a feminist non-fiction book edited by Jaclyn Friedman and Jessica Valenti, published in 2008. The book was one of Publishers Weekly's 99 Best Books of 2009 and inspired a sexual education non-credit course at Colgate University. The title refers to the popular, "Yes Means Yes" affirmative consent campaign against date rape, which calls for sexual participants to obtain a declaration of consent, "yes", to each sexual act or escalation.
