I’m talk enough to see over any barrier. The only time I don’t get at least a glimpse is if the guy is basically jammed into the urinal or if it’s really small when limp.
Haven’t seen any famous cocks but there are plenty of well endowed men who stand back juuuust far enough to put on a little show, if anyone is “accidentally” looking.
I’ve come to believe that this is a great way for straight men to get a hit/ego boost of someone wanting them. Especially straight men who are in unhappy marriages. I’m not even remotely insinuating these men are gay or anything else. I really do think it’s about feeling desired.
