Were they really having sex?

The main chicks plays her role so well, it's like she's either drugged heavily, or really depressed from depersonalization. Is she a porn star and what she really having sex in this?

Also, who the *beep* is this Lucifer Valentine guy? Like is he really Satanic? Cause I heard an interview with him and he seems so nice and gentle. It makes me feel like anyone can put together a weird film like this if they have the proper actors.
