All points valid and I hope and wish he'd hire you. It's such a waste of great potential. He's so easy on the eyes, his body is banging, and he has a rakish charm and a twinkle in his eyes that makes him so very appealing.
But I still believe that the core of this issue is that he continues to see a future for himself as a legit actor and so he doesn't want to cross that invisible line into full frontal nudity, with or without masturbation. If you look at how far he's been willing to go so far- jerking off (allegedly ) with his back to us, showing us his ass- that's pretty much on par with what many Hollywood leading men have done on film and television. And if challenged, he can defend himself as such.But I think showing full dick and cumming in plain view starts to feel like real porn and I'm sure he thinks that once he does that, he's closing the door on any major film and tv roles in the future. The internet is forever and those clips would never go away. Barring a leak from an ex, I think we have seen as much as we are ever going to.
