From personal experience, religious women tend to gravitate towards domination and rape fantasies. As one explained to me, these fantasies allows religious women to indulge in otherwise 'sinful' behavior. When they don't make the decision, they get to enjoy the action without the guilt.
My understanding is that also applies to a number of non-religious women as well. (Although they're probably pretty repressed sexually as a lingering issue from upbringing/cultural issues all the same) For pretty much the same reason. They've been taught that society doesn't approve of those things, and that "respectable" women don't go for that. So their fantasy life creates scenarios where they can excuse the behavior. ("I had no choice")
As I recall, Girls Gone Wild also observed a related effect in that regard where they started to make use of "Ringers" something many Spring Break destinations also use. Where instead of the "I had no choice" card being employed. They would have the ringer(typically strippers or previously established porn actresses) escalate the situation and by doing so they make the behavior "permissible" for that time/place. At which point the other women will do things they otherwise wouldn't consider. (In addition to the now extant social milieu of "Spring Break is your chance to cut loose and do wild and crazy things you'd never consider otherwise." Well, that and peer pressure.)
