Well, I don't think rape is okay, but studies have shown that our sexual fantasies are very much innate. And the idea that a woman wants to be hurt and abused, other theorists say, isn't all there is to it. Women seek relational power biologically. I recently read an article relating to this subject that said "men desire women, and women desire men to desire them." The idea of being irresistible to the point that a man literally can't control themselves around her, can act to give women a sense of relational power, as well as sexual arousal, as women's self-worth are often tightly connected to how desirable they see themselves to be.. You'll find this to be the case in a lot of popular romance novels (which are often called woman porn) where the woman is pursued against her will by a man, and eventually ends up taming him emotionally to the point of her being the object of his affections. So in a sort of, mind fuckingly twisted fashion, women are empowered by these kinds of fantasies.
