On the lighter side of movie sex scenes sits Mila Kunis as Jamie and Justin Timberlake as Dylan in the 2011 rom-com which is, surprisingly, about their strictly "just sex" relationship. Of course, the pair realise that by hooking up regularly, they've actually fostered a romantic relationship. It's not rocket science, but there are some pretty great sex scenes, including the scene that sees Jamie telling Dylan to "relax, you're not digging a hole to China" when he tries to go down on her the first time around (we've all been there). The scene ends with a pretty explosive (if not hilarious) screaming orgasm, and we could all do with a bit of that.
