The only reason there is even a debate over Criss' penis size is that he is young, incredibly fit and when his cock is fully hard (when it points almost stratight up while he's standing) it is HUGE.
In that gay scene Criss did, for example, he doesn't get fully hard.
Just like Danny Dong (Matt Hughes) only gets REALLY impressive in straight scenes.
John Holmes did gay porn, and his cock didn't get fully hard either.
They're straight porn actors. What do you expect?
Of course there are guys with 7" or less who'd like a hunk like Criss to be smaller, so they won't have to feel as bad. With Mandingo, the straws the're grasping at are along the lines of him being short or the camera lense adding a cpl of inches. But Criss is actually not that short. So what is it this time? You found one pic where he gets measured while his cock isn't even fully erect - that's your so-called proof? (you can look at the photo and compare it to a clip where his cock stands straight up... notice the difference?)
Sigh. Be proud of what you've got instead of embarrassing yourselves guys!
