Sexuality is a very deep well. I have spent 70 years close to all the major developments of breeding animals, and I've spent all of that same time with an open mind developing practical experience by engaging in as much sex as I could have with other people. Which has been, quite a bit. Just saying. So I venture an opinion, that is just me.
Every animal starts off as a female at conception. On the way to becoming a male from his female origins, and lot of things have to happen, and for reasons absolutely no one seems to understand, some men don't make it all the way. There is enormous diversity in the sexuality of gay men. We know that. And we know that you can't make a gay guy straight, not matter how rich his daddy is. And there is enormous diversity in straight men as well. Some are ass men, some are leg men. some are tit men, and no matter what you do, you can't make an ass man into a tit man. Sexuality seems to be imprinted somehow through the genetic process, during the fetus development.
So we have the condition that he actually is, sexually. But I grew up in a day and time that even your family wouldn't understand gay, and some outsiders would kill you or imprison you if they found out you were. I could tell stories about this. So, most gay people have developed a method that I call "compartmentalization". You are gay over here in this compartment and you are straight over here on this other compartment. You can't tell everyone everything. For instance, its ok to talk about being gay with someone you're fucking but not with your employer, in some cases. compartmentalization. I'm totally open about my sexuality now, but back in the day, not one person ever guessed that I was gay. I hid it entirely from people who shouldn't know, while I nearly fucked my dick off. Still today I don't discuss it within my family. They are not modern people and the topic would be difficult for them to handle.
