Porn films are to sex education what Hollywood films are to ethics or morality tales. Porn is fake. It may be very sexy fake, but it’s fake nonetheless. The sexual positions used in porn films are chosen not for their likelihood to turn on the actors, or even for the ways that the positions might allow for hot creative sex.
Sex positions in porn are chosen for the way they allow the camera to get wide open access to the genitals (which are still considered the main draw in porn).
While visual porn can be a good place to look for inspiration and ideas, mimicking what you see in porn is not likely to yield very erotic results. Plus who wants to wear all that ass make-up every time you have sex?
