I have a buddy that is 10.5 x 7 and he takes viagra before we go out clubbing. Half way through the night he is hard and stays that way for attention. But he also says he has to take it because his length and girth dont allow him to be hard for more than 20 min at a time. Have you heard of this? Someone being so big and think that they have to take viagara just to maintain an erection?
