No way. Avg chick in a bar has probably slept with 25-50 guys.....avg porn chick is probably well over a 100....who have also slept with a 100, who have also slept with a 100......it's just a numbers game.
As for the "testing," what a joke. So a chick goes to a clinic and gets tested, tests negative, goes home and has sex with 5 or 10 guys and brings whatever they have to the set, where she shows her "proof" she is clean for the next 30 days? Testing means nothing.
Brian Pumper had forged a girl's test, she tested positive for the clap. If you test positive for anything, you can't "work", from my understanding. His forging of the tests led him to be fired from Evil Angel...I think many of these girls do multiple scenes within a certain time period, with various diff companies...
So are you telling me, if you saw Alexis Texas in the bar and she was hitting on you, versus some random bar skank, which would you choose...and what if you know she just did a scene a week ago, but you know the skank has been with 6 dudes that you know of in the bar?
