Hey amongst all the low gravity biological experiments was there ever any zero gravity hetero lovin' experiments? I'm not sure how fun this would actually be (vs. work), as I read something in a space travel exploration book that said both parties would have to be anchored to a wall or something to enable the boom-boom movement.
Can you imagine giving your she-astronaut the first bump and her flying across the lab? There's a good monty python sketch in here somewhere.
