I've been peeing for 62 yrs. And I'm fairly certain I have never shivered. I don't look but I've been in enough public rest rooms to know if other guys were shivering I think I would have noticed. Never have noticed that! Are you sure the guys your looking at are peeing??
In third grade, I broke a girl's leg by accident. This girl also happened to be the daughter of the Youth Pastor at my church, and she was in a "relationship" with one of my best friends, so I got a lot of hate afterwards
