From my experience, there is nothing more to be expected from a "real" pornstar. Pornscorts are readily available in Europe and I've tried a few of them. One in particular was out of this world (Cathy Heaven) while the rest were rather mechanical experiences... These girls revert to escorting because the porn business is not doing so well these days so they're not really into it. Except for Cathy, forget the crazy sex you see on screen. They want your money and out.
After trying it now, I much prefer a girl who chooses escorting and enjoy what she's doing. Less hit and miss.
