Interestingly enough, I’ve reached my wits end with paruresis (shy bladder) and have stopped trying to pee in occupied public washrooms entirely. It’s pointless. I won’t be able to go. But I did find that if I just go to the stall and pretend I’m taking a shit, the pee flows like wine. Doesn’t matter if there’s one or several people in there. The real struggle is when the bathroom is initially empty, so I think I’ll use the urinal after all. You bet your ass thirty dudes walk in before I can start.
