Public bathrooms are gross, expecially at the gym. I do not have enough courage to enter that filthy room and put my ass on that disgusting toilet! Nope, nope, nope.
I rather piss in the shower. Yeah, of course it's a little embarassing because I do not know if someone is going to enter the locker room while I'm peeing in the shower that everyone uses .. they wouldn't be happy about that!
But I do not really care. For now it's my little, wet secret.
