You don't have to prove anything. Personally, I really appreciate creators and porn actors who don't feel the need to reveal their sexual orientation because it doesn't matter (speaking for myself, of course). When I talked about queerbaiting, I was pointing out that many creators say they're gay/bi because they know their audience cares about that, and they take advantage of it. Just to be clear, I'm not against you and I'm not attacking you, I'm just sharing my opinion.
The idea of 'gay for pay' has always made me skeptical, not because I don't think it's real, but because I feel like those who do it often seem uncomfortable and just do the bare minimum. So, I don't think they can be mistaken for someone who's genuinely comfortable with it. Basically, you can tell they're forcing it. But, that's just my opinion, and I'm not looking to argue about it.
That said I can tell you that you're a very sexy dude
