Does pretty much everyone reflexively pee in the shower?

I once had a conversation with someone who thought it was absolutely disgusting and went on and on about how abnormal it was, which I thought was strange because A) it seems to happen reflexively, B) it all goes down the drain anyway, C) I thought urine was sterile, and D) I guess I think it’s just kind of nice…but maybe that’s because girls don’t get to pee standing up very often :P
