'The Last Tango In Paris'
Considered one of the most controversial films in regards to sex scenes, it's hard to figure out how you're supposed to feel about this one. It's about an anonymous sexual affair between an older American man and a much younger Parisian woman. It's raw and animalistic, showing sex in a way that you rarely see in movies that aren't porn. But, unlike porn, it has a rather satisfying ending considering how the plot goes.
