Sex in Space: Why Zero Gravity Kills the Fantasy

Let’s be honest. Humanity has dreamed about sex in space almost as long as it has dreamed about space itself. Rockets? Check. Space suits? Check. Zero gravity sex fantasies?

But once you remove Hollywood filters, latex catsuits, and slow-motion floating orgasms (what ever it is), what’s left is a deeply unsexy cocktail of physics, safety protocols, and Velcro.

Astronaut Bodies Are Not in “Sexy Mode”

Long missions in orbit change the human body and not in ways that say “hot sexy video”.

Documented effects include:

• Fluid shifting toward the head (hello, permanent hangover face)

• Muscle loss

• Bone density reduction

• Altered blood circulation

Libido doesn’t disappear, but it definitely doesn’t get a cinematic upgrade either.

Even NASA has openly acknowledged that spaceflight changes how the human body behaves which is a polite way of saying “this is not a great place for experimenting”.

But let’s look at this rationally. I’m pretty sure that every space-faring nation has discussed this at least once. Just think about it: this is no longer really about sex, it’s about whether humanity can reproduce in space at all. The idea is brilliantly simple: to figure out whether humanity has any real chance of becoming an interstellar civilization. 🍌

The Practical Problems of Sex in Space Are Very Real

Even if someone actually wanted to try it, reality would step in fast.

Zero gravity makes physical contact difficult and body stabilization a constant challenge. Without gravity doing the heavy lifting, every movement pushes partners apart instead of pulling them closer.

Microgravity also affects blood circulation, which can directly influence arousal and erection. The human body simply doesn’t behave the same way in orbit as it does on Earth.

And then there’s fluid behavior. In a sealed environment, liquids: including biological fluids: don’t fall, drip, or disappear. They float, spread, and become a contamination risk that space missions are specifically designed to avoid. Taken together, these factors create serious practical obstacles. Not theoretical ones. Real, messy, physics-based problems that kill the fantasy very quickly. 💦💦💦

Pornhub Tried to Crowdfund a Real Space Porno (Yes, Really)

The space sex fantasy got so loud in the 2010s that Pornhub didn’t just wink at it, they tried to fund it. In June 2015, Pornhub launched a crowdfunding campaign on Indiegogo called Sexploration, aiming to raise $3.4 million to shoot what would have been the world’s first adult film in space. The plan was bold: send adult stars like Johnny Sins and Eva Lovia on a suborbital flight, train them for zero-gravity conditions, outfit a spacecraft with cameras, and capture zero-G intimacy on film.

But here’s where reality kicked in harder than a rocket launch gone wrong. Over the 60-day campaign, Pornhub managed to raise only a tiny fraction, about $236,000: nowhere near the $3.4M goal. The shortfall meant the film never left the runway. Still, the whole attempt became a media storm, turning the fantasy of “sex in space” into a public conversation about marketing, human curiosity, and how far people will go to pour money into cosmic fantasies.

Pornhub didn’t send sex to orbit. But it almost turned crowdfunding into a rocket booster for humanity’s weirdest project ever.

So… Has Sex in Space Actually Happened?

Short answer: no confirmed evidence exists.

Despite decades of rumors, jokes, and very confident internet comments, there is no documented, officially confirmed case of humans having sex in space. Not on the International Space Station. Not on Space Shuttle missions. Not even in some mysterious “classified experiment” folder waiting to be leaked. And yes, this question has been asked many times. By journalists. By scientists. By people who watched too much sci-fi.

At some point in the early 2000s, a rumor started circulating about a so-called secret NASA document describing sexual experiments in zero gravity. The story spread fast (by the way, few times) because of course it did. The problem? NASA officially stated that this document is not real: it’s a hoax, originally posted on Usenet and later widely debunked. No leaked PDFs, no redacted diagrams, no awkward mission logs, just a legend that refuses to die.

Banana Take: Hot Fantasy, Cold Reality

Sex in space is one of those ideas that lives perfectly in imagination and should probably stay there. On Earth, gravity is your silent wingman. In orbit, it’s gone, and nothing replaces it.

So yes, space is vast, mysterious, and beautiful.But when it comes to sex, it turns out Earth is doing a fantastic job already. Sometimes the sexiest thing in the universe…is a stable floor. That's one small step for man; one giant leap for mankind.

Here at Banana Collection, we believe that sex in space could absolutely have happened and not as part of some official experiment. If anything, chances are it happened despite the lack of an experiment.

Maybe it was passion. Maybe curiosity. Or maybe it was simply one of those moments where someone said: “Lieutenant Marisa, I’m drowning in your eyes: the same way Earth drifts through infinite space”. Science doesn’t like to talk about it. But humans have never been very good at sticking strictly to the mission plan. 🍌🚀 P.S. By the way, did you know that we run our own Medium?
