Sex in movies is often reduced to mood lighting, soft pop music, a bed, partial disrobing and some hazy camera work. (On the other hand, of course, there's porn.) But when a movie gets a sex scene RIGHT, the result isn't just titillating; it can be tender, awkward, kinky or passionate, and frequently all of those things at once. With that in mind, we've done extensive research to come up with the 25 best sex scenes of all time. Hey, it's a tough job, but somebody has to do it.
