You have your adult movies, and then you have your movies for mature audiences that have simulated sex scenes, and then you have movies for mature audiences in which the actors actually have sex.
Kinda makes you wonder what counts as sex, right? Kissing, fondling of breasts and bottoms, tangling of feet -- does that count? Or only penetration counts? What about cyber, phone, toys?
It has always seemed to me like it would be a lot easier to have the actors have sex than to deal with all the props and body sheets and so on to make them feel like they're not* really* having sex. Maybe not as fun for the props departments, but simpler and cheaper than making all the "don't worry, you're not really fucking" accoutrements invisible to the viewer.
About.com Sexuality guide Cory Silverberg compiled a list of non-porn films in which the actors (supposedly) have sex for realsies. (I haven't heard of most of the movies but I have a similar taste in movies to, oh, mainstream 13-year-old boys, so that's not surprising.)
