Porn is designed purely to be good to look at, so a lot of the stuff in it looks hot but isn't all that fun to actually do - a lot of the positions are actually pretty awkward in fact because they're meant to show the penetration. Think of all the really good sex you've had in real life and I can almost guarantee that if you had been able to film it, it wouldn't have looked all that great from the outside.
In terms of having seen a few things from porn films that I'd like to do in real life, then sure, but the idea of going along pretending to be a in a porn film with someone who's acting up like some kind of starlet, just seems awkward to me.
