I just can't like really!!!

I just had the longest argument with a man who said men cannot get raped and because their d*ck got hard then it's not rape... this irks me so much so basically what he is saying is that if a girl is getting taken advantage of and gets wet the it's not rape like really how can people be this dumb and uneducated... anyone can get raped from girls to boys from men to women. This just makes me so mad I just can't I can't. -_-
