A little ago he was asked during insta stories if he would pose naked for modeling. He said something like "I don't have a problem showing off my ass, but if you are expecting the front part, that's not going to come for any kind of money, I want to keep my privacy".
So... really sorry to bring sad news, but you can forget about watching his cock through insta or onlyfans or else. Unless some 'ex' shares pics or him or something, but I doubt that, he looks like a legit guy, probably never hurt anyone.
