Kinda jumping off from Mutt;s thread about making out, as a female I find it kind of hot but I know I'm not really target audience.
I think one of the hottest sex scenes I can remember in mainstream cinema is Jude Law / Rachel Wiesz in Enemy at the Gates-

Its hot for what you don't see, your mind fills in the blanks.
Thoughts? What do you guys think are some of the sexiest moments in R rated film?
