Good songs to make slow, passionate love to?

I'm not making love or anything. I need it for a film project for my
videography class.  yes, the film does involve "lust" and it's not a
porno. It's pure acting.
Something like Bjork's "All Is Full Of Love"
or Foals' "Spanish Sahara's" (mainly the beginning)
Listing as many as possible would be fantastic.

PLEASE. No Marvin Gaye or Barry White.
If I put that in my film piece and play it back to my professor, he's
going to laugh in my face.
