Let me preface this by saying, I know it's what the model agrees on, but I've noticed something lately in piss scenes that makes no sense; the models holding their hair back or putting it up before the pissing. Seriously, the models are doing the wrong scenes if they're worried about their hair getting wet with it. Might as well not even make a wet or piss version of the scene if the models can't handle it near or in their hair.
