Dude, that's creepy af. If you don't like the way he earns money, don't follow him. Outing him for it to his family is beyond. I get that you feel what he is doing is wrong, but he's never once said he's going to fuck a man in a believable way. His entire onlyfans platform is based on overacted rubbish that is clearly not real. That you're so upset you want to ruin his life and feel justified is gross.
Some of us enjoy the fun of it, some of us find it sexy, some of us just like seeing straight men pretend to fuck whilst actually naked and touching each other, and some of us just like his tight little virgin hole. Literally none of us believe he's actually fucking or being fucked.
