Other than Madonna I think that anyone in the mainstream industry would never step foot on set for a porno production due to the fact that they praise themselves a little higher in importance, as a person, morals, and for the sake of their fans as well as the media.

God forbid if they at least try it and perhaps enjoy it. But there would be so much negative talk and all the news stations would be on their asses better yet shunned. It's hard enough for mainstream to even accept a past pornstar to do a small role in the major film industry. ITS IGNORANCE! FUCKING IGNORANCE

... when in fact we are real people acting out real sex when these mainstream actors are performing a storyline that would only fulfill someone's fantasy by being another person they cant be! Yea so its a talent.

Every field has a talent to some degree in itself but id rather do porn that be in a movie, gawk over me for being hot and great acting ability.

I rather be gawked over for doing some hot nasty sex scene. Something I'd do in my personal life!!!! DAMN IT LOL
