I sit a lot of the time, as I don't particularly want to wipe up splatters every time I take a leak. I piss like a friggin racehorse, so it's not a matter of missing the bowl...it's a matter of splashback.
Does that make me a faggot? No. It makes me a married man who doesn't have his mommy around to clean his bathroom for him.
I stand up at all times. I tend ot have good aim so I dont have a problem. If I'm too drunk to hit a toilet(very rare) then I go outside where the world is a toilet and piss on a wall or a car or something.
