Terror can be an exciting turn on, hence the "rape fantasy". I dont know if its the "rape" that is the turn on or the actual terror caused by the fantasy rape? Would be interesting to find out.

I agree in reality once you want to be raped it is no longer rape because you want it, i dont think that ppl will actually want it real time though. Trust me, its not worth it. However in fantasy land, yeah rape is possible, anything is possible.
