How Do You Have Sex In Space?

You don’t. At least, you CLAIM you don’t.
That was basically the response of Alan Poindexter, commander of the Space Shuttle Discovery. At a recent press conference in Tokyo, Poindexter was quoted as
“Personal relationships are not an issue. We don’t have them and we won’t.”
There are two things I find amazing about this story.
1) There is actually an astronaut named ‘Poindexter’.
2) That people don’t have sex in space. I mean, c’mon!
First of all, there are more women being put into space than ever before. Don’t think me a sexist, I’m just saying that the possibility is there.
(Aside: Of course homosexual sex is an option, but I will assume it is less common than heterosexual sex.)
Second: How could you not want too? Zero gravity. The possibilities seem endless, and awesome. I find it hard to believe that these days, with astronauts (and cosmonauts) spending months aboard the International Space Station, that they don’t get lonely enough in the vastness of space to kill a bit of time with some space nookie.
Sure most astronauts are married or in a relationship. But I think its unlikely that it hasn’t happened at least once.
What do you guys think? You think its happened already? Or at least will happen in the future? Don’t be shy, we’re all adults here!
