So assuming good faith curiosity here, heteronormativity and compulsive heterosexuality are a thing. There’s huge social pressure to conform - as a child growing up I got constant messaging that one day I’d grow up, get a boyfriend, get married, have babies, etc. and so, starting to feel the pressure of being a late bloomer and not understanding that my awkwardness around other girls was because I was attracted to them (because that’s not like a thing), I found myself a boyfriend at 18 and we dated a few years because I really loved him and the sex was mostly enjoyable. But only a few months in I realized I was attracted to women, and it took a few years to fully accept it. Dating women is much harder, factually it’s a numbers game there’s just a lot less of us. But I dated a few over the years, and it took me seven years before I dated another man for a couple months, who I also love and I’m still good friends with today but we haven’t hooked up in almost a decade. And then there were a bunch of women since, some for a short time some for a long. I consider myself a lesbian through and through, although the label police will be like well acktually which is toxic as fuck. Obviously words have meaning but people have the right to express themselves as they see fit. Pedantic people would say I’m bisexual because I dared to sleep with two men in the last 18 years. I’d say I’m so rarely attracted to men that I actually stop and savor the moment when I do find one attractive, like seeing a rare bird or something lol.
So to answer the initial part about turning homosexual , I think sexuality is somewhat fluid and few people are 100% in either direction. Think of the most attractive male actor to you (assuming you are male). Would you be embarrassed if you woke up in bed (consensually of course) with them? Or would you be like damn alright well that was enjoyable but probably won’t happen again?
