I've been meaning to try some Italian sex comedies. Where Giallo gets a bit of respect (and, therefore, American releases) because of its ties to horror and especially slasher movies, Italian sex comedies don't so they're hard to get a hold of.
Since La liceale is the first I watched, I can't say that this is true for all or even most Italian sex comedies, but this isn't porn. The subject matter is sexual but the level of nudity is on par with Giallo. There's lots of toplessness and butts. Maybe the occasional bush on a woman (very probably a merkin but not an obvious one).
I read a fair amount of erotica, some of it historical. I ran into The Horn Book: A Girl's Guide to the Knowledge of Good and Evil recently in an article or blog post and it sounded interesting. Despite its translation to English being firmly in the public domain, the only options I could find to get it involved paying money to shadowy groups who publish public domain works for ... variable amounts of money. I try to avoid paying less than scrupulous people for things that are in the public domain but sometimes it's unavoidable.
The Horn Book (at least the bits I've read so far) is a dialogue between two lovers. The more experienced man and the married woman who's having an affair with him. She asks him to teach her all the things about sex that she doesn't already know.
