Sounds like "Muscle Man" here has a micropenis and was likely jerking off to pornography unacceptable amongst his peers. Why else would be so afraid of such a video?
Given "musclemans" hatred of blacks, Jews, and gays. I'm guessing the porn he was watching was of a12yr old Jewish black boy... With his micro-penis.
I dunno bout you, but probably more than half of my fb people, including clients, have seen me naked and a quarter of them have had sex with me or seen me have sex so a they get sent a jerk off video of me.... Not to mention my open star dick?? Pffft who gives a shit. Now if I had a mini cock like "middleman", I might... No, I absolutely would be embarrassed AF and would likely jump off. Cliff.
