My ex boyfriend could never get his penis up, never. it stayed hard for a few minutes but then got soft so we never did the deed. did I do something wrong? he said he jacked off earlier that day but I hear guys can pop a boner a lot in a day. I knew he wasn't attracted to me.. :/ I'm glad I didn't loose my virginity to him tho, he is a jerk.. and was addicted to porn. We've tried 3 times and he goes soft every time. Why? He was the one that wanted to do it too.
