With Virgin Galactic recently opening for business, the possiblity of having zero gravity sex in space has become a definite reality. All you need is lots of money...and to not throw up when you go into zero g. It seems that the fantasy of weightless spacebonking may well be better than the vomit-inducing reality, as Xeni Jardin at BoingBoing explains:
"...without careful choreography and helpful gear, physics get in the way. First, there's that microgravity-barfing connection. But then, Boyle writes...
Sex in space would likely be "hotter and wetter" than on Earth, Bonta said, because in zero-G there is no natural convection to carry away body heat. Also, scientists have found that people tend to perspire more in microgravity. The moisture associated with sexual congress could pool as floating droplets.
Hotter and wetter sex in this case being, apparently, a bad thing.
We're all for progress, but it might be best to stick to (near) zero gravity sex in the tried and trusted way, using a Love Swing (as seen on Sex And The City) or a Weightless Sex Chair - it's cheaper and there's no vomit involved.
