What It’s Like to Have Sex in Space

What would it be like to have sex in outer space? Is it even possible? NASA isn't coughing up any of the dirty details, but this list is full of scientific hypotheses on what it would actually be like in zero gravity. Cosmic coitus is a bit trickier than Star Trek led us to believe. Between one's inability to get it up while up there and the amount of Velcro straps that would be necessary to keep two people together during the act, space love seems like a black hole for romance. 

Although no studies have taken place specifically on how to do it among the stars, there is enough understanding of the body's reaction to zero gravity to make some guesses and, at this point, you've reached the event horizon. There's no going back. So prepare for take off. Next stop: lunar lovemaking in all its awkward glory.

  • While Astronauts Are Up, Their Junk Stays Down

    Before we get into all the dirty details about what would make lovin' super hard in space, let's acknowledge the fact that it probably wouldn't get hard at all. Low gravity messes with blood flow regulation, meaning it doesn't move through the body the way it does down on Earth. Getting down requires increased bloodflow to the male ~organ~, so without it (or with less of it), you're in for a more disappointing time than you're used to on Earth.

  • Sex in Space Is Likely Nauseating

    Space Adaptation Sickness is the cosmic equivalent to car sickness and affects about half of space travelers. It basically makes you super nauseous while your body adjusts to the lack of gravity and, although astronauts eventually acclimate, twisting all over the place during the act would probably have an adverse affect on your SAS. It's probably best to stick to the basics. Save the sexy space swirls for your second mission.

  • Ladies Stay Dry in the Sky

    It's not just men who struggle with the funky blood flow situation of zero gravity; on and off switches in women operate in the same way. Because the blood can't rush below the space belt as easily as it does on Earth, it would be really difficult for women to prepare for take off. That's just basic aerospace biology.

  • Any Fluids Would Pool on Your Body

    As a result of micro gravity, any fluids - bodily or otherwise - would simply pool at the area of secretion, because natural convection isn't possible in outer space. So, when astronauts perform their daily exercises, they still need to excrete toxins and cool off via sweat, but must constantly wipe the building layers of salty liquid from their bodies. While this wouldn't necessarily have an effect on sexual stimulation, it could get pretty gross.
