Only thing I get a little uncomfortable with, on occasion, is when the head my cock touches the front of the toilet seat. In any public restroom, I'm sure a million cocks have touched the front of that seat, and God only knows what kind of germs are being transmitted. As for my cock and balls touching the water, damn - I can only WISH I was that well-endowed!!! But ya know? I've used public facilities a million times, and I haven't caught any diseases yet, so to be honest, it doesn't bother me all THAT much..
