> "an actress begins moaning right after penetration"

Well, of course you're right... but porn is not a documentary, it's as fake as any Hollywood blockbuster!

Do you really believe Superman can fly and Spider-man shoots webs from his wrists?!? :-D

Porn is about men's sexual fantasies, what most of them would like to happen. It's the same (for women) in romantic movies: the handsome and rich guy who falls hard for the plain girl, and he promises eternal and unending love. Yeah, sure, it happens everyday! ;-)
