I don't because it feels like an invasion of their privacy.
I know, I'm a prude. Of course I've heard stories of guys getting caught by a psycho straight guy and loosing some teeth over it. Probably lies.
I'm right there with you GG.
I don't mind someone looking if I am purposely pulling it out to show them, but I don't really want anyone looking at me while I piss. I don't want to really watch anyone else piss. I don't want anyone to watch anyone relieving themselves of waste, period.
It used to be something that I had the urge to do, but I think I've seen enough penis to realize that I am going to enjoy one that is connected to a person that I enjoy being around more than one that is connected to someone that manages to still be attractive while urinating.
The excepttion to this is when I am smashed. If I am that drunk, I don't really care who is watching or what I look at. I just want to make it into the urinal or toilet and not get any on myself or anyone else.
