According to unauthorized and unofficial studies done in NASA's neutral buoyancy tank, microgravitational copulation practices are rather similar to subaqueous practices of the same nature. Much of the research into this field has dealt with the observation of dolphins engaged in mating behavior, resulting in the following findings:

It requires three dolphins to successfully mate. This is because at the critical moment, groups of muscles in the body spontaneously contract and relax, causing the two to drift apart as they lose hold of each other. Thus, a third entity is required to maintain frictive contact with the fornicants, allowing a ideal connection.

Logical extrapolation would thus assume that we could mate in a microgravitational environment, assuming that:

  • You could find someone to hang on.
  • Alternatively, you could buy a whole lot of velcro and micropore tape.
