Several studies have shown that it's common for women to fantasize about being raped. I think it's rare for men to do so ... This is relevant though not conclusive information.

It's not as relevant as you assume, because the description of these as "rape fantasies" is much too simplistic. Most often, such fantasies clearly reject many and perhaps most relevant features of actual sexual violence. (The wiki article has references for this info.) Women are most likely sensible enough to know this and take this into account, so the fact that they indulge in such fantasies does not tell us much about what kinds of men they want.
