I'd like to sign up for zero-g sex testing, I'd be happy to be on the forefront of space sex research
Dr Jason Kring, from Embry-Riddle Aeronautical University in Florida, is pressing Nasa to investigate sex in space, and possibly even zero-g pregnancy. Apparently there are potential issues like excessive sweating and low blood-pressure effects that might affect zero-g sex, as well as potential difficulties with the pill (like some other medications) which may not work as well in space.
He's also arguing for private spaces to be planned into crew quarters on the next Moon missions. Like drinking and eating, he points out that sex is a basic human function and "It doesn’t make sense to assume that these men and women are going to have no thoughts of it for three years." That's an approximate timescale for a round-trip mission to Mars.
