Yes, but it made me think...You've got the fluffers, right? Those chicks who warm up the guys before they hit the set.
And since these guys go limp in almost every porno you see, why don't they just have the fluffers in front of the camera since they're so good at keeping them up?
Why do you care if the guy goes limp or not? I would think you'd be happy to know that you're not the only one it happens to.
If you would go to fluffer school, maybe there wouldn't be a problem.
