I totally understand this, and have experienced it myself a lot, especially lately. I've always been sexually and romantically attracted to women since grade school, but I've just repeatedly, constantly, been rejected by them, even in both long-term relationships I've had with them--with them breaking up with me multiple times during the relationship, each time with them begging me to accept them back. So I've only had sex with 3 women, and hundreds of men in my life. Since breaking up with girlfriend #2 just before Covid, I've had no interest in ever having sex, let alone romance, with another woman, though I still find them attractive (except pussy, yuck, and the hourglass figure). From that moment on I've identified as gay, and I think that I've probably been mostly gay all my life, but I've just been fighting it. I am so happy and proud of my homosexuality, because it's me. Maybe this is why I keep posting the same over and over again in these forums, about my homosexuality, and how, like you, it really turns me on to say I'm a homosexual man, I am a gay man, and I love everything about homosexuality in people. But I don't think it's just in my head, some kind of fetish: for the last four years I have really loved to hang out with my large gay men's social group. I just feel at home with them, that these are my people. And the first time I had intercourse with a man (it was as a top), in 2013, was the greatest sexual experience of my life and I felt like I had come home, being inside of him felt like home, and sex finally made sense.
