In her new book “Girls & Sex,” Peggy Orenstein suggests that we re-think sexual intimacy, in both education and our everyday lives. While she acknowledges the importance of the national debate on campus sexual assault, Orenstein also urges us to broaden our definition of "sex" and talk candidly about what happens after consent -- arguing that if we don't guide our teenagers, pop culture will.
