Very few rapists do it because they would like to have sex. They get off on the violence or the power trip. THEY ARE DIFFERENT FROM ORDINARY MEN.
Probably from you. If you were single (or married) and famous and could get a lot of great women interested in you, would you find having sex with a drugged, basically unconscious woman be a great turn on? Would holding a knife at a woman’s throat, and seeing her beg for freedom, allow you to have a full round of intercourse with her as she struggles?
Rapists are sick. Not just horny guys.
I think we need to defer this question to CeeLo Green.
