What I've noticed is in porn there's a lot more over acting, much of it looks very pantomime. The over acting is particularly bad in amateur porn as girls compete in an over crowded market.
Now I've been fucked by hundreds of guys, good and bad, plus I've discussed this with similarly experienced women, and I can tell you most of those male performances would barely raise a smile let alone have us making dumbass faces, screaming, yelling the tired cliched porn phrases.
So question is how often do the women your with act like wannabe porn stars?
