Every popular dude on the hetero/hetero-ish side of porn would make a “killing” do “gay shit”. That’s really not saying much. But he’d probably have to depend on OnlyFans, as a lot of sites likely wouldn’t hire him. While the gimmick would get old quickly if he’s not any good.
The main thing I remember about him is him mid-key outing the “straight” side of porn, pretty much saying most of the dudes in hetero porn were doing queer shit off camera. And how a few performers urged him to be willing to do “gay shit” off camera if he wanted to make real money. That became one of the few things that made me realize that very few of these guys in hetero porn are both legit “hetero” when it comes to the sexual, romantic, emotion, commitment spectrum and refused to do anything with a man. Only a handful indulge on camera though.
What does make a killing doing gay porn means? Millions? I doubt it, especially since everything ends up on many sites.
Doing gay stuff off camera? You mean privates? I know some do, but most? I seriously doubt it.
