I used to very odd kid and mostly spent my life around girls from very early age.
I almost never had male friends which ofc changed in late teenage.
Now, don't find females that attractive and mostly spend time with guys.
Don't call me sexist or smth but I find it's more fun to work with guys. That's my preference.
I've been bombarded from young age (by pop culture, TV, magazines, porn) by thin women wearing make-up. I have a strong sexual preference for thin (fitspo thin, not anorexic thin) women and a strong dislike of women wearing make-up. Go figure...
Sexual behavior is definitely learned. But despite centuries of "theories" or convictions about "what experiences turn people gay", nothing has been identified scientifically.
Why it would be sexist? It's your personal preference and nobody's else but yours.
