sex! Many writers have turned their imagination to the subject of what sex would be like in zero gravity. The general consensus seems to be that it would be like a Two-Person Pool Party without the water (examples involving more than two people are hard to come by, as no one enjoys dealing with the three-body problem). Unfortunately very hard to pull off, due to the lack of gravity having weird effects on the body, including (ahem) blood pressure. Zero-G is more accurately called "free-fall" because one is literally falling. Zero-G sex is sex while perpetually falling. The microgravity environment would also mean that the couple would be a slave to Newtonian physics, meaning that any... vigorous movement is going to cause both to careen wildly around their spaceship, resulting in multiple possible injuries. As of early 2012, this is not known to have been attempted in any actual spacecraft, despite the attempt of a porn studio to hire Spaceship One for the purpose. Virgin Galactic declined the offer, nominally on the grounds that accepting would make their company name exceedingly silly. As of June 2015, a porn website has launched a $3.4 million Indiegogo campaign to fund a video of sex in space; exact plans are unclear, although they do claim to be "in talks" with launch companies. There was one married couple that did fly together on STS-47: N. Jan Davis and Mark C. Lee, who had met and then married secretly during training, and told NASA so soon before the flight that there wasn't time to send a replacement. However, if they attempted this trope—which is itself highly doubtful—they aren't talking about it, and neither is anyone else. Somewhat surprisingly, The Other Wiki has a page about this too.

- Y: The Last Man mentions this in an early issue of the series. Later, it becomes a major plot point.
- Referenced in Astro City: Astra Special #2. Astra's boyfriend tries to persuade her to indulge, leading to this exchange:
Matt: But hey - If they can do localized anti-gravity... I don't know, maybe these guys don't care, living in a cosmic place like this. But I'm from Earth, I'm a guy. Seems to me no-gravity would be pretty interesting for, y'know...Astra: Sex? They live on planets here, Matt. They do have gravity. Trust me, you're not the first to think of it. They actually have rooms for that, up near the top, where the effect is the strongest. But it's messy, it's awkward, you smack into the walls a lot, and then you have to clean up and it's kinda gross.
- Buffy and Angel do the 'flying without a plane' version when Buffy develops (more) superpowers during the "Twilight" arc of the Buffy the Vampire Slayer 'Season 8' comics.
- Starfire and Captain Comet indulge in REBELS #18.
- Several pin-ups in the collection MILFs From Mars from Eros Comix feature the eponymous MILFs engaging in hot girl-on-girl action in zero g.
- Happens in Ethereum Gladiator, given there's no gravity outside the Nethercity's ecodomes.
- Last Child of Krypton: In this crossover Shinji is Superman and Asuka Supergirl (in the rewrite). In the epilogue they make love floating between Earth and the Moon. Given their bodies were modified with Kryptonian DNA with all it implies (flight, invulnerability, capability to hold your breath virtually indefinitely...) they had no trouble pulling it off.
- A decidedly not worksafe, but surprisingly well-written Deep Space Nine fanfic, "Nothing Like The Sun". Notable for being one of the few DS9 fics to center around the marriage of Miles and Keiko O'Brien.
- A Mobile Suit Gundam Wing fic by Talya Firedancer has Heero and Duo having sex in a spaceship. Lampshaded rather snarkily by Duo when he sings a parody of Fly me to the moon after the deed is done.
- James Bond and Holly Goodhead in Moonraker, making Bond both a member of the Mile-High Club and the 100 Mile High Club.
- Coupled with a major Getting Crap Past the Radar: "James, take me around the world one more time!"
- Dracula 2000. Although this used vampiric levitation instead of zero g space.
- Also done in Underworld Rise Of The Lycans, where a vampire and a lycan have gravity-defying sex while hanging off the edge of a cliff.
- The sci-fi horror film Supernova (2000) featured sex between several of the characters in zero-gravity areas of the Medical Ship.
- The comedy Moving Violations suggests the main characters, played by actors John Murray and Jennifer Tilly, have an intimate encounter in a weightlessness simulator.
- Private Media Group filmed a brief scene for the space-themed pornographic film The Uranus Experiment in a Russian aircraft flying a parabolic track (similar to NASA's Vomit Comet). The Uranus Experiment features around 20 seconds of actors Sylvia Saint and Nick Lang (who portray astronauts living on a space station) having sex in freefall. The scene was controversially nominated for a Nebula Award (as a protest against the Nebula Awards' Best Screenplay category), but did not win.
- Aki and Gray in Final Fantasy The Spirits Within.
- In Thank You For Smoking, there are plans to incorporate this trope into a movie. Along with cigarettes, of course.
- In Cube 2: Hypercube, two characters, feeling that their deaths are inevitable, have sex in the center of one of the cube rooms that has zero gravity (and possibly accelerated time) until they apparently die of dehydration and eventually desiccate. One of the other characters, moving through cubes with different time flows, comes across their mummified corpses still entwined and spinning in the middle of the room.
- Word of God states that original scripts for Sunshine had a planned sex scene between Cassie and Capa.
- So Long And Thanks For All The Fish describes Arthur and Fenchurch having Their First Time while flying. It's not technically zero-g but the Hitchiker universe's method of flight makes it effectively the same thing.
- Science fiction and popular science writer Isaac Asimov made conjectures in writing about what sex would be like in the weightless environment of space, in 1973 in Sex in a Spaceship. He anticipated some of the benefits of engaging in sex in an environment of microgravity. He also mentions 1/6-gee sex in the final chapter of The Gods Themselves, which takes place on the moon.
- In Ben Bova's novel Kinsman the astronaut characters consider founding the Zero Gee Club; like the Mile High Club, but higher.
"Think of the possibilities.""Hmm. Three-dimensional."
- Lois McMaster Bujold's Falling Free:
- Inverted when a girl specifically engineered for free fall (with a second pair of arms instead of legs) wonders how 'downsiders' can have sex without bouncing apart, since they have no lower hands to grip their lovers with. Her downsider lover explains that gravity has its uses. She also points out that condoms sure beat chasing bodily fluids around the compartment with a hand-vac.
- At another point in the series, Miles acquires a zero-g "bed," and decides to give it a whirl, musing on the rumors of the fantastic nature of sex in zero-g. He crawls out a few minutes later after deciding that the bed smells like "at least three" people had recently been investigating those same rumors.
- Used in at least one Robert A. Heinlein novel (Time Enough for Love?).
- Eric Idle in The Road to Mars described it as "like having sex inside a water bed."
- In contrast to QI, the novel Red Lightning has a scene discussing the advantages of sex in zero gravity.
- The BattleTech novel "The Price Of Glory" finished with the afterglow of such a scene, with the couple in question "turning gently".
- Spider Robinson goes into heaps of detail in his Stardancer trilogy, including pointing out that a couple making love unrestrained in zero gravity will inevitably end up bumping gently against the air vent — and any foolish enough to try to avert this by turning off the ventilation will suffocate in their own exhalations.
- In the Alan Dean Foster novelisation of Alien, Parker tells Brett about an inexperienced visitor to a zero-G brothel who started spinning during the 'act', and then started throwing up. In zero-G.
- Newt Gingrich's books talk about the possibilities of having your wedding night in space. Al Franken, in Rush Limbaugh is a Big Fat Idiot, made fun of this, pointing out that it would probably be quite awkward in reality.
- Something similar involving buoyancy instead of gravity occurs in Alida Van Gores Mermaid's Song: mermaid sex requires either a heavily padded cave or lots of searoom given the unavoidable propulsive effects of the undulations involved.
- In one of The Witcher novels Geralt reminisces some Yennefer's "experiments", including use of a levitation spell on them both.
- Vernor Vinge mentions the problem of obtaining leverage during zero-g sex in A Deepness in the Sky; also, one of the protagonists in A Fire Upon the Deep thinks that zero-g sex isn't what it's cracked up to be (again largely due to the difficulties of obtaining leverage safely).
- In The Sparrow by Mary Doria Russell, Anne and George have one suggestion: duck tape.
- The Red Mars Trilogy mentions that this happens frequently on the initial voyage to Mars. One of the Russian characters also apparent experimented with many forms of zero-G sex while on Novy Mir.
- In Known Space, zero-g sex is far from uncommon, due to zero-g "sleep fields" which work anywhere. At least one character thinks the sleep field is the greatest invention since sliced bread... But prefers to sleep on a traditional mattress.
- In Stephen Baxter's Manifold: Time, it's mentioned that one spaceflight saw frequent zero-g orgies because the astronauts had no better way to pass their time.
- In Peter F. Hamilton's The Night's Dawn Trilogy, the Lady Macbeth has a fold-out zero-g sex cage. It's probably not a unique piece of equipment.
- Inevitable on Gemworld in the Star Trek: Gemworld duology.
- Mentioned in Naked Lunch.
- In the sci-fi book Fallen Angels, one of the spacemen (who have lived most of their lives in orbit, and so have severe issues with living in gravity again) wonders how people make love in G. His observation? "They probably don't need Velcro."
- Dread Empire's Fall has "recreation tubes" for the inhabitants of their starships. They work for up to two occupants and presumably have versions for all of the species that could be crewing their ships.
- Characters do have sex in space aboard spacecraft and both deep space and orbital facilities in the Star Wars Expanded Universe. Normally this would be done under artificial gravity, however artificial gravity in the Star Wars universe is variable both directionally (outer decks on both Death Stars had gravity following the curve of its hull like on a planet or moon with inner decks all being oriented one way, Super Star Destroyer Lusankya's prison wings were upside down relative to the rest of the ship, and Millennium Falcon's gunwells have gravity at angles to the rest of the ship) and in field strength. This makes gravity manipulation to spice up one's sexual encounters a very real possibility.
- Not to mention that Force users can levitate both themselves and others...
- John Varley’s Titan: “Cirocco liked space, reading and sex, not necessarily in that order. She had never been able to satisfactorily combine all three, but two was not bad. In the second scene she is not reading...
- More John Varley, Red Lightning: “So the basic or ‘missionary’ position in free fall is for the girl to wrap her legs around the guy and lock her feet together, and for the guy to hold his legs out straight and try not to let his curling and uncurling toes shove the two of you all over the place.” But Ray and Evangeline use “positions emphatically not for the beginner.”
- Attempted and failed in Constellation Games by Leonard Richardson.
"Man! Those suggestive docking sequences in sci-fi movies make it look so easy. Don't they teach you how to do this in astronaut training?"
"No, they just tell you not to do it."
"That's what they told us, in high school, but nobody listened."
- Larry Niven discusses the difficulties in low gravity sex in The Patchwork Girl.
- In Arthur C. Clarke's Imperial Earth, travelers from Saturn to Earth have a few hours of zero-gee halfway along, while the ship is flipping over to decelerate.
Live Action TV
- This subject came up on QI. Stephen Fry pointed out three drawbacks to this: your you-know-what will be smaller, you have problems maintaining contact and there's the danger of fluids drifting around the cabin and getting into equipment. Not that this deterred Bill Bailey and Alan Davies from vividly describing the possibilities of space porn in front of an embarrassed Stephen Fry.
Bill: I'm here to fix the turbo-thrusters.
Alan: Then you'd better come through to the sleeping module.
- This came up on a particularly good game of Press Conference on the British version of Whose Line Is It Anyway?, in which Tony Slattery had to guess who he was - the first man to make love in space - by the questions Stephen Frost, Colin Mochrie and Ryan Stiles asked him. In case you even needed to be told, there were double entendres galore.
- Red Dwarf references it while making fun of regulation numbers: "No officer with false teeth should attempt oral sex in zero gravity". And again: "Hey, Pop-up Kama Sutra! Zero-gravity version, that's mine!".
- The idea was floated (if you'll pardon the pun) in Salvage, the pilot for the TV series Salvage 1. However, being a PG sort of show, nothing comes of it.
- The Red Shoe Diaries episode "Weightless".
- Defying Gravity: Done with the Cranes in the pilot.
- This topic was the focus of the final story on the night of June 29, 2010's Countdown with Keith Olbermann. He struggled (without success) to keep a straight face. They showed clips of a History Channel documentary about the subject in which two speculative experts postulated that "One thing everyone does agree upon is that one or more of the mating partners needs to be restrained."
- Dave's sexual fantasy on NewsRadio is making love on the Space Shuttle...with a space prostitute.
- Buffy the Vampire Slayer:
- "Once More With Feeling". At the end of Tara's love song "Under Your Spell" she levitates into the air over her bed, and it's strongly implied she's doing it so an off-camera Willow can perform cunnilingus on her.
- Buffy and Angel during the "Twilight" arc in the Season 8 comics.
- This is, of course, in the issue "Them F#©%ing (Plus the True History of the Universe)".
- Steven Spielberg's Taken miniseries did this with the mating of the two Half-Human Hybrids who produced Allie.
- Not quite genuine Zero-G, but a couple on CSI: New York got busted for public indecency because they were having sex while bungie-jumping. It's strongly implied that this is the female jumper's personal favorite kink.
- In the Deep Space Nine episode "Melora," the titular character is an alien from a planet with very low gravity, and it is strongly implied that she and Dr. Bashir get it on in her quarters with the gravity turned off.
- The National Lampoon had a pictorial zero-gravity sex guide, the NASA Sutra.
- There are a few Filk Song treatments of the subject, perhaps the best-known example being "A Reconsideration Of Anatomical Docking Maneuvers In A Zero-Gravity Environment" by Diana G. Gallagher. She makes a good point and gives another good reason (in addition to the existing ones) for restraints.
- Mastodon performs a song about Intercourse with You in space. The title? Stargasm.
- Arjen Anthony Lucassen's song "The Space Hotel" from the Lost In The New Real album mentions making love in zero G.
- GURPS: Biotech mentions, for no apparent reason, that the modifications that would make someone especially useful as an engineer on a starship also open up all kinds of kinky possibilities.
- A spoof document claims that NASA had conducted experiments on the feasibility of sexual activity in zero-gravity environment.
- There was a (PG rated) zero-G romance scene in Final Fantasy VIII.
- In Tales of Symphonia, when the heroes go into outer space because the Tower of Salvation goes extremely high up, an optional cutscene has (who else?) Zelos going on about this, and (who else?) Lloyd completely missing the point (Zelos didn't actually mention sex, which is probably why Lloyd didn't get it; Also because he's an idiot).
- 21st Century Fox:
- Unity: Sam and Juni, sitting in an observation pod...
- Discussed in this Questionable Content strip: apparently the problem of zero-G sex isn't just physics, but killer robots as well.
- Used a lot (not all the time due to artificial gravity) during space travel in The Journal Entries.
- And in keeping with the way the series is written, it is also mentioned that it can be quite awkward, particularly for those new to the process, and that it offers some unique possibilities. (Ken doesn't normally like suspension bondage, but with microgravity available, he once puts a centaur in suspension bondage.
- Shot down in the Cracked article 6 Reasons Space Travel Will Always Suck. Sex in microgravity will fail for at leats two reasons: a man needs gravity to make enough blood pressure for an erection, and embryos need gravity to develop properly.
- In We Are Our Avatars, Used as a way to convince Black Baron into giving up his piece of the device.
Imca: ....Ummmmmm, why don't you retire in space. You can make a movie out of it. "Pimps in Space"..... "Bitches in Space".... whatever you want to call it. Not that I would approve of those but negotiation....
(Black Baron thinks about it for a moment.)
Black Baron: Well, the ladies do like the ol' space horizontal tango...
...Ah, what the fuck. Ya'll mothafuckas got yerself a deal!
- Futurama has a magazine called "Zero-G Juggs" that Scruffy is often seen reading that plays with the idea of this trope, even if only the name is shown. Use your imagination.
- Peter Griffin of Family Guy once masturbated in space. He later said that the inside of the shuttle began to look like a snowglobe after a while.
- Archer: Sterling Archer and Pam, whom he had stowed away specifically for the purpose in "Space Race Part 1".
- Though this is not known to have been done by astronauts, there have been experiments performed on reproduction and development of rats in zero-g environments. Yes, these experiments have included rats mating in zero g. The rats were not reported to experience any particular difficulty with their end of the experiment.
- As mentioned in the introduction, there has been one married couple in space together, but the details of their marital activities during the mission, if any, are unrevealed and likely to remain so.
- According to an article on Haaretz Extra about the late astronaut Ilan Ramon, there is just so much to do in a space craft that no-one has any energy left to have sex after that.
