YES, BIG TIME and I've rarely shared my theories about this.
#1: Most men are gay or bicurious, and our society isn't largely 100% accepting of that all across the US, so it's dudes checking each other out, or seeing "who is in their society" if they're 110% hetero like you :D
#2: If most men are not bicurious (VERY POSSIBLE according to science stats), then they're doing it to see what their COMPETITION is, what they're up against.
Consider this: More straight dudes peak at the urinal than gay guys. one, gay guys constantly at dick so they don't need to see a rando's for 2 seconds when they can go get railed for like 8 hours. two, gay guys have already "seen" enough cock to know what "their competition is", so they don't need to know.
So in this event, let's say you have like... a small package (yours is JUUUst right madness) then you see ppl like us at the urinals and ur like "ok I better go to the gym and get MORE RIPPED than these guys" or you are like "I better get really rich so I can offer her a lot of $$$ and stability"..... and this would be a productive social coping strategy for still having an attainable, happy life you want.
#3: Men are more psychologically curious about the mental health/state of others close by to them, and or are more hyper-vigilant/on guard than women due to higher testosterone levels (and the NE is likely higher too AFAIK).
There's also not so much a theory but maybe you can make one out of this, women if they feel other shoppers are too close to their butts when looking at an item on a shelf, are less likely to actually make the purchase. So stores deliberately give enough "butt space" for feminine target audience products.
It could be that it's a preventative measure because if a woman is making a lot of eye contact, maybe she subconsciously fears that would lead to a stranger raping/groping her, or is just not interested in making eye contact with people they don't know (perhaps because their husbands might be the jealous type?)
There's more I could theorize. I tend to side with #1 or #2. They could both be right.
