Basically what the title says. If given the chance, what is something you’ve wanted to try out? As simple as a threesome, or maybe pegging a pregnant midget. What would you like to do?
I’m going to have to rain on your parade. Sex in space would not be a fun experience. You would need at least one partner to be tightly tethered/immobile to even make it possible most likely. Even then it would not be a satisfying experience with how weird the momentum conservation would work.
