This isnt even a gay thing, this is a social and privacy/personal space issue. Don't pick stalls that are far apart because "it's gay," do it because other people might feel uncomfortable being near other human beings period (might get stabbed or robbed, might get harassed, or might just have extreme social anxiety - the most likely) while their privates are exposed and they're in the middle of something.
Unless there are huge dividers between each one. Then it doesnt matter as much.
If dividers weren't shorter than most moderately tall dudes I wouldn't care but I've caught one to many weirdos taking a peek over the wall to ever be comfortable with someone in the next urinal.
I was a dumbass accidentally once. Three urinals, I chose the middle one. A father and son walk in and have a conversation through my head, across the top of me peeing.
