This is a rather dark question, but why are some guys into rape if they already have a gf and have no trouble hooking up with girls they've met at bars and clubs?
It's a power thing.

Because rape is not AN ACTO OF LUST OR DESIRE. It is a power thing. The man, who hates women because they have the power to excite him, has to revenge himself by using what power he has - brute force - to degrade and demean them so he can feel superior again. It doesn't work, which is why most rapists are serial offenders.

Men rape men too, bro. Everybody rapes everybody, actually.
