When talking to a friend yesterday (our one-post Matalo Matango user) about good porno movies, he also told me that I should see Behind the Green Door. The world is a small place and I still have a lot to learn 
He also has Shortbus in his Top Ten for 2006 I believe, and I guess I'll have to seen it soon after also initially avoiding it (I was thinking not another "serious" Hollywood film about sex ).
