I’m sure I do this on rare occasion. I have no idea why.
Helps with more complete relaxation of the muscles involved.
Why…So the wall doesn’t fall on them when they are standing there with their lizard out.
You think the walls have more germs than the faucets on the sinks or the door handles?
I usually have to stand on something so I don’t dangle into the cold water.
Yep. 
I just checked. My left thumb is busy holding the elastic of my boxers down. My right hand is occupied otherwise.
Therefore, I cannot lean on the wall.
I tried. My hand got sticky.
Which one?
I’ve only ever seen old guys do this; I figured that there may have been some meme back in olden times that if you used both hands you were some kind of fruitcake or something.
I may put one of these in our house. We have a urinal in the main floor bathroom, and there’s a discoloration from where DH leans his forehead. I didn’t realize it was a common thing for guys to do!
when I first read this I had a WTF moment (I’m on meds and have an excuse.) I thought "how the hell does he piss while he is on his back? I thought you were making a joke I wasn’t getting.
The well endowed undergo a dramatic shift in their front-to-back center of gravity as they whip it out, requiring support from the front.
No. Which is why I use a paper towel, my elbow or the flap of my jacket to touch those. As I said, I’m a bit of a germophobe.
And as long as this is a urinal-themed thread, I’ll put this here:
Who stole the urinal out of the men’s room? Would you please put it back? Seriously.
At the urinals at work, I’ll rest my forearm/elbow on the top of the urinal flush valve. At home, there’s a cabinet over the toilet, and I’ll oven rest my forehead against it while I pee.
Saw this at a ski resort in Montana once. It was awesome.
I vote for “inobviously intoxicated.”
I had actually been thinking about starting a thread on this exact topic. We have a couple of guys at work who do this and I seriously don’t get it.
One guy does moan. A LOT.
Yeah, what is the significance of the moaning supposed to be? When I think about moaning in a bathroom, I think about something you wouldn’t do where other guys could see you.
Want! Well at 2am on a Sunday morning.
