well shes more right than you are. yes its possible to piss when you got wood but you gotta relax, and not clench that muscle thats like between your shaft and balls. when you are have sex you are clenching that muscle the whole time, everything is much tigher and its impossible to piss. ive had to piss before i start having sex, then when im doing it i dont have to at all, i couldnt if i tried, then after i nut, i relax, everything softens up, i take off the condom and piss. bullshit on pissing in the butt. people are just believing it because either theyre inexperienced or because they want to because its funny.
