Favorite sexual (non-porn) movies?

Shooting this out there to see if any have some good suggestions. I am not asking for pornographic films, but movies about sex or something involving it. In fact both of my initial suggestions don’t have much if any nudity. The first was all covered / underwear sex (that I recall) and the second never went pass negotiation between the prostitute and client.

Strictly Sexual - At one time this was the most watched movie on Hulu... and its still there for free with commercials . Two wealthy women gave up on dating and hire two men for just sexual purposes. Its an indy film so don’t expect this to be like Hollywood. I see it more of a romantic comedy for men than anything else! If any of you who RP with me before wonder why I like playing a male concubine role, here it is. Trailer: http://www.youtube.com/watch?v=vhw71DyXj4s

Chicken Ranch - A realty movie documentary from the early 80s about the real prostitutes at the famous Nevada brothel. This is only partially if anything related to the illegal one in Texas and inspired “The Greatest Little Whorehouse in Texas”. It opened 3 years after the Texas one closed down and had some of its memorabilia. I don’t know much after that. The one filming was focusing mostly on living as a prostitute, and ended prematurely. The owner is an asshole and that’s all I will spoil. My only problem with it is how hard it will be to find out what happened to these people, 30 years later.

Kissed - Ever since she was a young girl, Sandra Larson (Molly Parker) has been fascinated with the darkness of death, but when she takes a part-time job as an embalmer at a funeral parlor, her obsession consumes her every desire. As her boyfriend (Peter Outerbridge) struggles to relate to her new lifestyle and her love of the afterlife and the study of necrophilia, he jumps through hoops to prove he'll do anything for love.

Suspicious River - Self-destructive, fatalistic, married receptionist Leila Murray (Molly Parker) plays prostitute to several willing guests in the hotel where she works, and she spirals into a heated romance with a sadistic lodger who allows her to be raped. It all started off as a means for her to make more money, but soon, it seems that her behavior might lead her to the same fate as her mother, who was brutally murdered.

Kissed is kind of weird but good. Suspicious River is really good but starts kind of slow.
