Why, if you where talking blood and guts (open heart surgery) I would agree with you but Playboy.
no offense or anything, but I have seen HD porn, and it is not a pleasant thing to watch. SD covers up a lot of the more disturbing flaws on the typical porn stars body.
I realize it may just be me, but I am not really interested in seeing track marks on the performers in a porn. kind of a gross out.
