In Space Everyone Can Hear You Scream
I had a friend who worked with NASA, and he had this conversation with them at some sort of official place (I actually think he has a paper out on it). The main issue was birth control and pregnancy, with concerns about the effects on the embryo of radiation on re-entry being the biggest issue. He said that hearing officials in the space industry seriously debate enacting a “anal sex only” rule to be one of the most surreal moments of his life.
