Decent question, but also difficult to discern without a huge amount of older gay data to compare it to. Best current guesses are in utero hormones or immune response, effectively making sexuality matrilineal. But there’s no clear answer
Evolutionary pressure to survive, for one, since we need heterosexual intercourse to breed. I’m all for freedom in this regard, but come on, heterosexuality is the default because it’s how we evolved and thus what the species needed to survive. Explaining how it’s the default is good as part of the greater understanding in science, but you’re probably not going to have success trying to study it in isolation, you want to look at the “exceptions” and figure out where and how they diverged.
Let’s turn around the question, what causes heterosexuality?
Let’s zoom out. Maybe all sexuality is just “I fuck the people that I think I will enjoy being around based on patterns I’ve observed”
