Another vote for Short Bus, and Pillow Book. I also liked Spetters, but that has a different tone of young-adult sexual coming of age.

I know we had an erotic film thread somewhere, but that might have been in a previous message board - My favorite of the genre include:

Bitter Moon - for creepy seduction and humiliation
Henry & June - Sexual Adventures is pre-war Paris
Dangerous Liaisons - I like just about any retelling of this one for the pure game of sex and seduction
Last Tango in Paris (I've really come to love Bertalucci's treatment of sexual subjects - The Dreamers, Stealing Beauty, Sheltering Sky - I all love but certainly am biased
Repulsion - For some early Polanski repressed sexuality (I also enjoyed Knife in the Water, but didn't like it as much in a second screening).
Eyes Wide Shut - I know people have problems with this
Belle du Jour - Housewife takes a day job as a call girl
Chocolate - Because the next best thing to good sex is chocoalte
The Unbearable Lightness of Being - for certain scenes
