Awhile back, I was in Minneapolis' airport and had a layover long enough to eat lunch. After eating, I had to piss. In the restroom, there were three urinals fairly close together, the center one lower than the other two.
You could have knocked me over with a feather when two bodybuilders came in, right after me, to piss at the other two urinals, the taller at the other tall urinal, the shorter at the center one. And the shorter guy--holding his thick uncut one in his left hand, showing his wedding ring--quite unabashedly looked to his left and right as he pissed, obviously checking us out. I caught his eye and he looked back with a bland expression and looked back down at mine, then turned his head to look at the other guy.
I couldn't help but be amused, he was so matter-of-fact about checking us out. I know he thought it was a normal thing to do, and I'd be willing to bet he was a little surprised that we weren't doing it as openly and unashamedly as he was.
I saw him later with his wife and several small kids. He caught my eye and nodded one of those unspoken greetings that straight men often give each other, but he certainly didn't act at all ashamed that I'd caught him turning his head and staring openly at my cock for longer than a moment.
NCbear (who wishes that others could be as frank and open about their interest in seeing cock as this obviously straight guy was)
