Gross thing guys do in the bathroom

I see this all the time, peeing in someone else's owe. That's the most disgusting thing you can do. It's like being blood brothers with someone you don't know. You just mix your fluids with theirs you might as well kiss them on the dick. That's too hard core for me I'm not peeing in pee or peeing on poop. I'm not ready to be that connected with a stranger.
