The Graduate (Mike Nichols, 1967)

I have to add to this list one of the best films of all time, of course. The Graduate is simply perfect from every point of view, including the subtle approach to erotica. It was my main inspiration when I shot ​I Found Your Mother On Tinder​ though this short film was more like a postmodern approach to the MILF myth. Mrs Robinson is still the most gorgeous, elegant and deliciously perverted MILF of all time. You literally saw nothing of the sex between both characters, but just the image of a young Dusting Hoffman helping Mrs Robinson get dressed, or the subtle tan marks on Mrs Robinson's shoulders, were enough to trigger your imagination to the next level. It is quite a sad film in the end, though.
