Bad sex scenes

AAAAARGH!!! I've had it up to here with bad, gratuitous, overwritten, ridiculous sex scenes. The hack writer seems determined to get his characters down and dirty repeatedly in his script. Yet interestingly, expect for cases where the sex is totally integral to the plot, like Disclosure. (And I have NO idea why Disclosure was the first film that leapt to mind there. I haven't even seen that film in something like 15 years), I can't think of too many major studio releases with long, on-screen sex scenes.

Sure, there's plenty of setting up the sex and then showing the aftermath. And yes, this usually involves getting the attractive leads into some state of undress, but are there many movies where we're voyeurs for much of the act? My gut says no.

So hit me with your sexiest moments in film. I'm curious to see how many of you name actual sex scenes versus scenes that are content simply to tease.
