this is pretty much exactly how i got myself to become comfortable taking a piss in the presence of my girlfriend. i had her sit on the tub, blinded, gagged, and deafened while i pissed. now i'm used to it and am comfortable, and have really learned to enjoy the sweet somethings she utters when i'm emptying my bladder -- who knew urination could be so much fun?! now i never piss alone unless i have to.
