Oh, dear.

Though it's cold and lonely in the deep dark night.
I can see paradise by the dashboard light.

Coitus in an MRI tube. From Pharyngula: science porn.

I have to admit, though, that although it sounds like an experiment that was a great deal of fun, they didn't learn anything too surprising. They notice that the penis is more contorted than expected, although I had to wonder if that wasn't just a consequence of the difficulty of having sex in a narrow tube. Intromission didn't seem to do much to the female anatomy (no surprise, again), but one interesting observation was that the female reproductive tract does jigger itself around in curious ways during arousal and orgasm.
