well first of all i have no clue about whether or not any one so far has had sex of any form whilst being inspace, however i do know that scientists are trying to figure out what will happen to a fetus in zero gravity conditions for those journeys that are going to take generations to reach desired places and for those places we may eventually collonate, and they even have a husband and wife astronaut pair to have sex inorbit to see if it is even possible to concieve in zero gravity situations.

i'm just going to scout around now for the web pages pertaining to this. shall post again soon
