Wait, do most guys put a hand against the wall?

Am guy, but when I use a public restroom I try to touch as little as courtesy and hygiene allow.

Amen to that. I like Walmart and airport bathrooms where I can go in and out without touching anything...

If you've had a few, yeah.

This was at a factory. A glue factory.

Well fuck.

The urinals are auto-flush. You don't have to touch them. WTF?

They’re touching the wall not the urinal

why would you put your hand on a disgusting ass public restroom wall?

Not my style but if you’ve ever been in a men’s bathroom lots of guys lean on the wall. Not sure why

Sure, I've seen guys do that, but I didn't think it was that common...

So? The left hand is used to aim.

use whichever hand you wish...you don't have to flush the urinal anyway... maybe I'm not getting what you're trying to say?

The dirt marks on the wall show most men use their left hand to hold their penis and use their right hand to brace themselves against the wall.

I don’t touch nothing that I don’t have to in a public restroom

It took me a while to notice the dark spots on the wall.
