I Piss In The Shower

I piss in the shower when I have turned off the water. I always have, it’s just a thing I do. I don't know why? I'm not even sure when it started? 

I never even thought anything about it until I heard people criticising other people for peeing in the shower when the water was running. 

How can that be a bad thing, I thought?

All the while I'd turn off the water. And have one last pee before I get out. I am very good at aiming it down the plug hole though, I might add. If that makes anyone feel any better? 😬
