Flutterby™! : Top 10 Sex scenes

The Guardian offers two competing lists of the best sex scenes in the Cinema, produced by Premiere and Playboy. I have seen most of these, but I have some quibbles. The famous scene with Veruska from Blow-Up is great, but I prefer the purple paper scene with the two teeny-boppers from the same film. I haven't seen the Bardot version of And God Created Woman, but I have seem Roger Vadim's 1988 remake with Rebecca De Mornay and Vincent Spano, which has a zipless fuck scene that untied my gym shoes. Any other entries?
