1. Two Moon Junction (1988)
Trashy film starring Sherilyn Fenn from Twin Peaks.
Rich girl hooks up with a bit of rough from a travelling carnival. Lots of sex. Randomly also starred some quite famous, respectable actors including Academy Award winner Louise Fletcher.
There was a straight to video sequel called Return to Two Moon Junction, starring Melinda Clarke, in which I worked in the wardrobe department.
Not as good as the orginal.
2. 9 1/2 Weeks
Starring Kim Bassinger and Mickey Rourke before his face got messed and up he was still sexy and dangerous.
The title is how long their kinky and sometimes abusive sexual relationship lasted before she leaves him when he starts to get controlling and jealous. Sex with food. Sex in the rain in an alley. Sex in public. Cross dressing (her). Lots of sex.
This is Steven Soderbergh's first film. It's about sexy people; James Spader (who is also in another film on this list), Andie MacDowell (Four Weddings & a Funeral), Peter Gallagher (sexy eyebrows) and Laura San Giacomo (Pretty Woman) talking about sex and having sex with each other.
4. Secretary (2002)
This is what an actual BSDM relationship is like...not 50 Shades of an Abusive Relationship. It stars James Spader as a lawyer who has a very interesting relationship with his secretary, Maggie Gyllenhaal. Very sexy movie.
