@sakyo:
It seems to me that a lot of actors in porn can't maintain their erection, ie when they have close body contact during foreplay, or even during some oral scenes the dick is half soft. Does anyone spot any real erections in porn where the actor maintains it from the beginning to the end? The one comes to my mind is Kevin Warhol, at least his erection in a lot of his clips seemed genuine.
Dirk Caber usually has a rock-hard dick from the beginning to the end
