Pee shy a.k.a pee anxiety --
You have to pee
like a champ....
unfortunately, when you get to that public urinal it is to quiet. You fear your peeing sounds will be to loud (echoing throughout the numerous other stalls) so you are unable to release your urine.
A fear that another person is
listening to you urinate, your muscles tighten up, no matter how hard you try you cannot urinate.
