As it becomes more and more likely, it is sounding less and less appealing. In fact, I would say downright gross; as Richard Johnson of the Times Online writes (snarkily) in “The 400-mile high club“:
Well, if space tourists are planning a dirty weekend with lots of astronautiness, they ought to know the facts. It will be hotter and wetter than on Earth as there’s no natural convection to carry away body heat, and humans perspire more in space. The moisture associated with sexual congress (and we’re not just talking perspiration here) will gather in pools, and fly off goodness knows where.
Forget it. That’s just yucky.
