Zero-gravity erotica has already been done...
The adult entertainment production company Private Media Group has filmed a movie called The Uranus Experiment: Part Two where the zero-gravity intercourse scene was accomplished by flying an airplane to an altitude of 11,000 feet (3350 meters) and then doing a steep dive.

Berth Milton, Jr, president and CEO of Private Media Group, says "You would not want to be afraid of flying, that's for sure!"
