>>81868095You're asking the wrong question.
The real mystery is why do gay male tops exist. Gay male bottoms are easy to explain: hormone screw-up in the womb during that early timeframe where fetuses get permanently established with whatever kinds of behavioral tendencies they'll have for the rest of their lives. Gay male bottoms are basically just male bodies with female behavior.
Gay male tops however make no sense at all. There's an animal model for gay male bottoms you can make in a lab by castrating mice, but no such model exists for creating gay male tops.
So either gay male tops are straight guys who got very desperate, or they're gay male bottoms larping as tops to make it easier to get a bf or something.
