When I was in High School, I was a wrestler and played Soccer.
Only slept with girls but had same-sex fantasies about a couple of the more sculpted guys on my wrestling team.
We had gang showers back in those days, and there was no modesty in the locker room...so you always got a full view of everyone naked.
Had a couple of friends in my social group who I could tell were gay ( but nobody really discussed that openly ). ZERO interest in them. ( too effeminate )
Never approached any of my team mates, assuming that I was the only weirdo ( bisexual )...& didn't even know that was a thing outside of my own reality.
Plus would have probably gotten gay-bashed for trying...so kept my same sex interests to myself and continued to fuck girls.
To this day, that young sculpted athletic masculine male who I remember from High School and College is still attractive...(although I certainly don't chase after high school students today)....20 to 30 y.o. athletic and str8 acting does it for me best. No preferences about nationality/ skin color etc.
