That is what you would do, or believe you would do if you reacted such. There are more than 6 billion other people on this compost heap of sorts who may not react the same. Some of them are male, some of them have experienced rape, and most of those (as ShadowBoxing replied) who are in both categories can remain sexually confused for the rest of their natural life. No one person's experience is a complete generalization when it comes to rape, and some people may just have no arousal. But that doesn't stop the fellow next to them from reacting in a different manner.
