Scandalous Pleasure has a valid point, it is a question of defining what turns the reader on. As for women being worried about rape, that's understandable, but in many situations, like war or being incarcerated in prison, male rape is a very real risk too, if not a certainty.

As for 'pleasure', I think SP is only thinking of the victim, because in totally non consensual sex it is the rapist who is getting the pleasure, and thereby also the sadistically inclined reader. It just depends which side you empathize with. I suppose the only satisfactory answer to this dilemma is for authors to cater for all scenarios, and make sure the nature of the text is clearly defined in the titling.
