My boyfriend was completely mad at me and didn't even want to lay next to me to go to sleep. yet when we did lay down he had a massive hard on.. is that normal to get an erection when you are really mad at someone and completely turned off by them at that moment.
This is just sooooooooo misinterpreted by females who have no hope of understanding this completely.
They happen when guys are alone and not aroused by anything in particular. Morning wood is a good example
