I know it's a personal question, so I won't ask if you do it or not. Why shouldn't one do it though? It's kinda weird when people are around, but if no one else has to stand in it, what's the problem? Even so, you're gonna wash your feet anyway. Thoughts?
Urine is sterile and it washes down with the water. Sometimes I'll get in the shower before using the restroom. I don't want to get out and get the floor wet with water so it's no big deal just to pee like a boss.
From someone who recoils at the very thought of doing this, no, I have never done it before. My shower's really small (it's one of those ones surrounded by glass at the corner) so if you tried you would probably hit the wall and that wouldn't be very good...
