Married or not…it’s discouraged. I’ve NEVER been in a situation where I was weightless; however, it looks like it would be awkward to move around & very difficult to accomplish. Even self pleasuring would be a difficult task to accomplish.

A quick google search will answer this much more accurately than any of us could, unless we have have some secret astronauts on fluther.

Keep in mind that some activities would be almost impossible without the advantage of gravity.

My info came from an astronaut that was stationed on the international space station for a considerable length of time. She said the rules were NO sex. She & the crew were giving a tour of the ISS & how they do normal everyday duties. Even when sleeping, they are basically in a sleeping bag & strapped to a wall so they don’t float around the area. Although there are some married couples in the system, they are NOT normally put on the same mission to make sure that they can’t even try to join the million mile high club.

When these people eat, they have a pouch of pureed foods that provides them with nutrients. ALL their drinks are in a pouch as well. If any water or whatever escapes, they have to catch it & put it in their mouth so they don’t have too much trash floating around the area. Even going to the bathroom is a big production. It was a documentary put out by the government to answer Qs the average person seemed to have at the time. Anything said after the first original sentence is MY opinion & seemed logical to me after watching how weightlessness affects everything they do!!! If you’re interested, you may watch the documentary, but I’ll warn you that it’s about 2 hours long. I found it interesting.

I would find it impossible to think that people had never even studied sex in space…

I am an avid reader of scientific research studies, and we have conducted experiments on just about everything 1,000 times…

For those claiming gravity would negate certain activities, you aren’t a creative consumer of pornography. There is underwater porn. There is skydiving porn…

I almost talked a hot coworker into having sex in the Grand Canyon. We were in Arizona, attending CE classes.

We ultimately didn’t. But. We seriously considered it. We had no relationship outside of work. But. She thought about it… Because…....LOCATION. LOCATION. LOCATION.

Space, the final sexual frontier!

The question was specifically about NASA’s rules governing sex in space. Maybe another Q could cover everybody’s space porn fantasies.

What happens in space stays in space.

^Wear no one can hear you complain…......

As a 100% real astronaut myself, I’m not going to disclose this information.
