I’ve been thinking about the Fifty Shades books. Why were they so popular? Is it true that a big percentage of women have rape or submissive sex fantasies? If so, why? And what does it mean? Does it affect their lives outside the bedroom? Does it prevent them from dominating in other fields? You reference a book about how to achieve orgasm. I’m interested in reading one that puts rape fantasies in sociological, historical and psychological contexts. Any recommendations?
