I remember the BBC (or Ch4) made a set of documentaries a few years back that showed people having actual sex for educational purposes. I can't remember the name. Most porn is certainly made for commercial rather than educational purposes though and idealized stuff with giant penises and huge cumshots seems to be more commercially successful. Effectively it's more about fantasy and than reality.
