This is basically around two sets of relationships that are connected by friendships & a former relationship. One is two lesbian women. In this instance since one has a history (which isn't exactly made clear) with the BDSM scene the other named Jamie but uses Sally at a BDSM club, decides to try it. The other is a woman in a relationship with a bisexual man who is then allowed a relationship with a gay man. The story bounces back & forth between the two relationship sets occasionally the friends only which doesn't add much.
First, I need to say I did not like any of the characters in this movie. Second, all relationships seem to be incompatible and no sense is given as to why they continue. If you don't care about the characters themselves then you won't care too much what happens to them. There were some laughs very early on but then I really found both the characters & story very, very sad.
The title indicates this movie has an S&M theme. It is really just a small subplot to the first relationship. Should mention there is no nudity and the S&M is barely shown on n screen.
I came across this movie a few years ago but from the description it didn't interest me. I chose it at random tonight. There are evidently two movies that somehow are precursors to this one. I guess I'll skip those. This really was a lousy movie tho I have seen worse.
