Is anyone making creative, hot, erotic D&S, S&M, B&D and B films?

I think it was easier to say film makers were making erotic films in the 70s because they were breaking taboos. But since then, and especially recently, and specifically BD and SM, it's only been 9 1/2 Weeks, Secretary and Lars von Trier's Nymphomaniac Vol. I & Vol. II. I can't think of any others, and all three of those films were about dysfunctional people. A creative, intense, intelligent, healthy film about people who love B&D and S&M still has not been made. Secretary comes the closest, but strangely is not a very erotic (hot) film, it wasn't going after that, I believe.

There seems to be a social disconnect when it comes to BD, SM, in that, the idea of depicting it in a positive yet very erotic way is not on film makers minds. I believe the public wants it, but why isn't it here? Has anyone even tackled creative and edgy role-play in a positive, fun light?
