How difficult would it be to have sex in space?

Question

or any other place with zero gravity?

Answer 1

The problem in space is that there's no gravity to keep you in one place. So if you exert a force against someone, both of you are going to move in opposite directions. This could make things tricky. However, if people ever do live in space in large numbers and for long periods of time, rest assured they'll figure it out!

Answer 2

Technically, it would not be very difficult at all. Assuming that both persons (and I am assuming a "both", haha) start in a state of equilibrium, i.e. they are not moving in any direction, then any forces they exert against one another will mostly cancel out against the other person, and they will stay mostly fixed in space. If it were possible to maintain this equilibrium, then sex would be no more difficult than, say, having sex while floating in warm water, except that you wouldn't have to worry about drowning.

This is, however, only in a perfect situation and will probably never happen. Any unbalanced motions, or even just exhaling, would move them in some direction albeit very slowly, and eventually they will collide with a wall or object. So even though it will not actually hurt them, it will probably be distracting. And once they come into contact with an external object or surface, any slight push against that object/surface would result in them moving in the opposite direction and probably at a greater speed. In time, they will probably be literally bouncing off the walls. Not fast enough to hurt from the impact, but certainly risking the possibility to hit any sharp objects or corners. The lesson here: Do it in a padded room. ^.^

Probably the worst effect, though, would be the open spin. Both people would easily be subject to any amount of spin along any axis. For most people, this would be extremely disorienting unless they were very used to it, and would likely result in severe motion sickness. Imagine yourself tumbling head-over-heels and simultaneously rotating left-to-right in the middle of the room you are in now. Getting sick during sex is probably not the most attractive thing in the world. ^.^

Answer 3

You asked a physics question, I'll give you a physics answer.

Successful sex is dependent upon sustained periodic motion, like things going in circles, things on springs, and pendulums. I think that 'springs' is a starting point. The springs could be used to pull things together or pull things apart and the muscles could provide the force in the opposite direction.

The other solution is the replacement of gravity by something else that will accomplish the same purpose. Straps, handles, Velcro, surfaces to push against.

It has never been published by NASA that I'm aware of, but I'd bet a nickel that it has already been done. Further, I'd bet that someone planning long term space missions has already designed the mechanisms to facilitate it.

Answer 4

It would be easy.

If you jumped out of a plane with somebody and had an infinite freefall together, aside from the wind, that would be the wieghtlessness experience. Other than the upset stomach sex would be easy. The whole thing about them going flying in the other direction is silly. You're wieghtless NOT massless in space. It would be easier than sex on Earth because you'd not have to hold yourself up, you'd just have to hold on to your partner to provide the necessary opposing force to whatever pushing you do.

Easy peasy.

Of course, you would move around a bit based on whatever starting momentum the two of you had, and whatever later interactions with walls of the spacecraft you had. So it would probably be a case of strappin on to somepart of the craft or wearing padding LOL. mmm.. sex with helmets.. awesome!

Answer 5

Hi Prof Einstein
First is is neccessary to find out what really warps space whether gravity is a push or a pull?

However ;There is nothing like a scientific experiment! I am sure if you ask NASA THEY MAY HAVE SOME DATA>

Answer 6

Great question! It would be very easy, unless you forgot your Viagra... Just intertwine your legs together. Or fashion a rubber belt. That all assumes the traditional missionary position. The man wouldn't need anything but strong arms for a 'from the rear' position, and the woman on 'top' with strong legs could easily be successful. (who is on top in space?) In other words, from a pure physics perspective, gravity is not necessary for copulation.

For reference, you could train in a pool with scuba gear, believe me, that's been done...

Answer 7

Just the slight touch of the erected penis would push her off to the other end of the spaceship! Unless the girl has her arms and legs tied up, then it will help a little.

But hey my first idea wasn't pretty bad, why not a little tease and come and get play before sex?

Answer 8

difficult?? do u mean how fun?? try sky diving u might feel more or less de same as space cos no reaction force on u, ie u ll oso feel weighless, juz rmb to open de parashute=)

Answer 9

I would be glad to volunteer my time to help research this vital question.

My theory is that with the right equipment, it might be the very next thing.

Answer 10

It may look like a rape. You have to tie her down to the ship to avaoid her floating with you. then start pumping. You may have to hold on to something not to go away
