Pretty sure he does hardcore porn under a different name. But I can't remember what it was.
Can't imagine. There was an interview with him on YouTube ("Tania's Truth Talk") which apparently has been deleted since I can't find it anymore. He was asked in this interview if he could imagine doing hardcore porn and he answered that he doesn't want to do hardcore porn because he'd be afraid he wouldn't be booked for mainstream movies anymore. This interview was many years ago, but I can't imagine he changed his mind since then, even though there are no new softcore movies anymore and new "mainstream" movies featuring him are pretty rare.
He really should consider doing hardcore porn as long as he's not getting too old for this, he still has the perfect looks for it and if you're looking at his Instagram profile you can see he's friends with many porn stars, for example Bridgette B. So he could use his connections for getting into hardcore porn if he wants to. Or he could at least create an OnlyFans page lol.
