I think he is embarrassed by his cock. He will have been asked if he is ok with nudity before filming The Voyeurs. He has said he was ‘mortified’ going nude in the Judas Kiss, basically saying he didn’t wanna do it but felt he had to as a young unknown actor. Later though he says he is glad he did it and found it ‘liberating’. If this were true you would assume he would say yes to his real penis in Voyeurs later on. I imagine what happened was that he was getting over his issues with his size, was asked to undress at the audition where the producers instantly knew he needed a prosthetic, because he would playing a manipulative dominant guy who has lots of affairs and makes women orgasm like he did on screen. This just wouldn’t have been believable with his real dick. Ben will have known that this was the implication, he was perfect for the role except his cock so my guess is the producers made him wear a prosthetic. And now he’s got size issues again. But pretends he doesn’t. Saying he’s “sooo comfortable” in his body that he wishes he could “whip his kit off” when he’s at the beach. “But I won’t”. Like yeah no you won’t. This is supposed to be LARGE penis support group. He tried to fake it but we know the truth.
