** In ''Literature/StormFront'', [[spoiler:Victor Sells prepares powerful death curses by holding ritual orgies during thunderstorms.]]

* The ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' fanfic ''[[https://archiveofourown.org/works/32334151/chapters/80154481 All the Trashy Novels:]]'' Played for laughs. Zelda has been trying to unlock her ancestral divine sealing power for years, and is absolutely ''mortified'' when she discovers that it activates when she orgasms. She immediately insists she needs to find an alternative--her embarrassment aside, it's not exactly a practical way to seal away an ancient evil that probably won't let her pause the final battle to have sex with her boyfriend. Eventually, she discovers that it works on ThePowerOfLove; love of her country, her friends, and her family all work. She just happened to stumble on sexual love first.

* It's strongly implied in ''Film/{{Ghostbusters|1984}}'' that this is how Louis (possessed by the Keymaster) and Dana (possessed by the Gatekeeper) summon Gozer.

* The whole plot of ''Fanfic/FemaleTransfiguration101'' centers around a spell she finds in a book named ''Female Transfiguration'' that allows her to [[spoiler:[[{{Hermaphrodite}} grow a fully-functioning cock]].]]

* ''Fanfic/WanderingPilot'' plays this straight and inverts it. [[Anime/NeonGenesisEvangelion Shinji]] gains [[WhiteMage healing abilities]] [[PowerPerversionPotential that make the girls of]] ''Anime/QueensBlade'' [[AccidentalPornomancer extremely randy]]. Upon ''having'' sex, [[DeusSexMachina he makes them even stronger]]. Since this is [[SociallyAwkwardHero Shinji]], he originally ''hates'' this power as he would rather use it as a last resort, and this itself caused problems to him as well. [[spoiler: It gets him hunted by the Church and on one occasion he gets captured and raped by [[SlimeGirl Melona]].]]

* ''VideoGame/FearAndHunger'': This sort of magic falls under [[OurGodsAreDifferent Sylvian’s]] domain, creation. Alongside more traditional [[HealThyself healing magic]], “showing love” to Sylvian almost entirely revolves around sex-based acts, often with healing as a side effect, as shown with a [[{{Cult}} group of bunny-masked people in the titular dungeons]] who are having an orgy, in which partaking heals the party. Of course, thanks to [[BlueAndOrangeMorality the drastically differing standards of the Old Gods]], it isn’t always cut and dry. [[spoiler: Showing love to another adult or a Ghoul on a ritual circle will result in you forming a [[FusionDance Marriage]], healing lost limbs, with a helping of BodyHorror as well, with further love showing either turning you into [[BodyHorror a fusion of three or more people gone wrong on the ground or an even more twisted Abominable Marriage]], and attempting to [[PaedoHunt show love to a Demon Child]] predictably [[EvenEvilHasStandards has Sylvian]] [[NonStandardGameOver smite you]]]].

* ''Series/{{Grimm}}'': Adalind casts a spell to strip Nick of his Grimm power that requires her to sleep with him in order to complete it. She uses a glamor to pretend to be Nick's fiancee, Juliette, so he'll willingly sleep with her. To reverse the spell, Juliette has to use a glamour spell to look like Adalind, [[{{Squick}} forcing Nick to willingly sleep with a lookalike of his rapist]], in order to get his powers back.

* As does Tantrism, which is actually the most famous real-life case. In short, Tantrists, believe that, if all is ultimately one (a near-universal Hindu doctrine) then all dualism (such as good and evil) is erroneous. Therefore, Tantrists use sex, meat (forbidden in many schools of Hindu thought), and intoxicants to conquer these inhibitions and realise the oneness of everything.

* ''Webcomic/BlackHole:'' Paranormal investigator Diana Nox has sex with various paranormal and supernatural entities and uses her tantric magic through the act to drain away their energy.

Few if any of these mages use sex magic exclusively. It's more common for that to be one option for a witch/wizard, rather than the only option.

* ''Literature/Illuminatus'': Sex Magic is a key part of Discordian practise, and Hagbard Celine is implied to have used it to turn [[spoiler:Marilyn Monroe into the physical embodiment of Eris]].

* ''Anime/QueensBlade'': Nyx can only use minor fire spells on her own. So, to power up, she allows her sentient staff (Funikura) [[CoitusEnsues to bang her.]] During which, it forces one of its tendrils in her mouth and makes her swallow several large mouthfuls of what appears to be semen. Which results in a near split-personality style transformation, as she changes [[ExtremeDoormat from doormat]] to [[TheDogBitesBack 'revenge mode'.]]

Most often, the sex involves two (or more) people, but a downplayed version of this trope has the mage employing ADateWithRosiePalms instead.

* In the "Black Science" arc in ''ComicBook/TheInvisibles'', Lord Fanny is shown powering one of her spells with masturbation. ''The Invisibles'' also includes a rather unusual example in its ParaText: during its early run, the sales of the series dropped notably, and author Creator/GrantMorrison (who practices magic in real life) was worried it would get cancelled. To prevent this, he suggested a massive, multi-person [[ADateWithRosiePalms "wank-a-thon"]] on the letters page of one issue. The idea was that all the readers would masturbate on a particular date while focusing on a magical sigil Morrison had provided, and the resultant Sex Magic would stop ''The Invisibles'' from getting cancelled. Unfortunately, this particular issue was delayed, so it came out only after the date Morrison had set, though the series was never cancelled anyway.

* ''Film/TheCraftLegacy'': It's indicated that the [[LovePotion love spell]] Lily casts on Timmy requires sexual energy, plus a [[SympatheticMagic connection to him]]-she [[ADateWithRosiePalms masturbates using his shirt]] while casting.

* Season 4 of ''Series/BuffyTheVampireSlayer'' used spellcasting as a means of hinting at the [[HomoeroticSubtext lesbian relationship]] between Willow and Tara, leading to a scene in "Who Are You?" where the two {{Hot Witch}}es invoke a spell called "[[SexualEuphemism the passage to the nether-realm]]". This involves them HoldingHands and getting all sweaty, breathing faster and deeper until they fall backward in ecstasy with a [[TheImmodestOrgasm giant flaming "O"]] rising around them. So perhaps not a literal interpretation of this trope, but the audience was certainly [[DoesThisRemindYouOfAnything expected to get that idea]].
* On ''Series/TheMagicians'', Quentin and Alice use a spell like this when Penny gets trapped in the Neitherlands because he can't figure out which [[PortalPool fountain]] leads back to Earth. When they first attempt it, they have trouble because the spell requires simultaneous orgasms. It finally works and Penny finds the right fountain... which teleports him to Quentin and Alice while they're having sex.

* ''TabletopGame/WarhammerFantasy''[=/=]''TabletopGame/Warhammer40000'': The Chaos god(dess) Slaanesh is the living embodiment of desire, so it has control over (and is fueled by) pain, pleasure, and all manners of excess. [[note]] In [=40K=], it was actually created after the highly psychic Eldar engaged in millennia of hedonistic orgies to occupy their very long lives.[[/note]] While the sex aspect isn't used on the tabletop ([[Rule34 but fans are all too happy to make up for its absence]]), fluff contains a lot of references to pleasure cults that try to obtain hir favor or conduct rituals ([[Literature/CiaphasCain summoning daemons, for instance]]) this way.

For this trope to be in effect, you have to have an actual spellcaster having actual sex for actual magical purposes. James Bond administering a SexFaceTurn to a minor female villain doesn't count, because he's not a mage, but a wizard using sex to set a mind-control spell on their partner would. While HornyDevils often drain magical/life energy from their partner(s), this trope doesn't kick in unless said horny devil is using the energy to immediately ''do'' something rather than merely as nourishment. The latter cases fall under VampiricDraining instead.
