"Urinal etiquett" has always been a hurmorous curiosity. You'll see guys looking straight at the brick wall in front of them, maybe just inches infront of their nose, just to be absolutely CERTAIN they don't accidentlly catch a glimpse of some other guys' tool.
I'm taller than most men, and I do admit that I will take a curious peek to the left and right. being as tall as I am, it's easy without having to turn my head at all. I just need to look at my own peeter, then roll my eyes left and right.
One time, I caught a guy, much shorter than me, obviously taking a good look at my stuff while we were standing there doing our business. So I said out loud, "ARE YOU ENJOYING THE VIEW??" He quickly looked straight down at himself, zipped up, flushed, and left. He didn't ash his hands or anything.
I didn't mind...It's not a big deal to me. I don't try to hide myself. If somebody wants to look at mine, I consider it a compliment.
