i wonder if women would have to.... it might take some synchronizing though.... dont touch the door as you walk in as you walk in behind someone, kick open the stall.. pull down pants and sit down.. hold door still with feet.... when you're done, flush with your leg and then walk out behind someone else without touching the door...
a guy could do it too, but peeing with no hands, like driving with no hands, could make you reckless....
