Have a look at "The Uranus Experiment 2", it stars Sylvia Saint and had some snippets of sex scenes filmed in zero gravity.

They shot those bits on the Vomit Comet, an airplane that flys in a parabolic flight path so those on board can experience weightlessness.

Vomit Comet,

I so want to have a go on that thing.
