Slightly related…
I was at a wall urinal once and caught the guy beside me moving more than normal.
I sneak a peak to see wtf, and dude had flushed the urinal and was scooping water out of it as it flushed and splashing on his dick. At that point I was in sanitary shock. He flicked it dry and walked out. Didn’t even wash his hands. I think my jaw was slack for thirty seconds just trying to process how any of that sounded like a good idea.
It was a flea market bathroom, so I guess maybe that’s normal
