Chaykon said: No. You would have to aim your penis almost parallelly with your body, aiming up, to be physically able to piss
I'm able to piss while erect. Straight up, mind you, but I'm able to do it quite easily. Not easy if I try to aim down though.
Chaykon said: And you can't piss while cumming no matter what, because the terminal urethra is connected to your ejaculatory duct at the time, and not to the bladder.
Correct, though this function doesn't work correctly for some men. I remember something about that from the Sunday Night Sex Show, way back in the day.
