I've read that when a guy's dick is hard, it shuts off to their bladder so they can't pee while they are hard. Even my bf can't pee while it's hard. It's real hard to pee he says. He has to wait for it to get a little soft before he can get some of it out but it's still hard to go. he has to wait until it's not erected anymore before he can easily go.
So anyway I just had a little fight with my online friend. He said I was wrong and he doesn't care what I read and he knows more than I do. I got mad and told him f**k you and go call me a liar. Heck even I have been told by a incontinent guy online he doesn't pee when he has sex because it shuts off to his bladder. It was the same with my ex too, he was also incontinent. But my friend claimed he has peed while he had an erection. Perhaps his was soft enough for him to go.
