History Main / SexMagic

* 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 "[[IsThatWhatTheyreCallingItNow 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]].

** When Izuku began to research sex-quirks, some examples he found included a quirk that induces orgasm through touch, one that causes someone to fall in love with them and one could even cause DeathBySex.

** All witches possess at least one unique ability. Zoe Benson discovers her ability to [[DeathBySex kill people she has sex with]] when [[spoiler:her boyfriend violently hemorrhages to death during their first time]]. They call it "Black Widow" if you needed a label for it.

->''"Use sex magic to destroy his fear of you and to open the floodgates of love. Only then will he see you as a human-being with all of your inner beauty."''

* ''Dragon Pink'': Pias is an elven sorceress, who has to regularly have sex in order to replenish her mana. She can give herself a momentary boost in power by performing oral sex, but gains a far greater surplus by taking it directly into her body, via intercourse. The women of her race of elves are usually barren, so [[ButICantBePregnant Pias was shocked]] when she eventually [[SurprisinglyRealisticOutcome became pregnant with Bobo's child.]]

** In ''VisualNovel/{{Tsukihime}}'', the twins Kohaku and Hisui are "Synchronizers" who carry large amounts of {{Mana}} that can be transferred to others, [[spoiler:which has the side effect of suppressing the [[VillainousLineage "inversion impulse"]] in those with demon ancestors]]. For most of the story they use this ability by allowing others to drink their blood, but if Shiki becomes close enough to one of the twins he can have sex with them for this purpose. In the BackStory, [[spoiler:this transfer was carried out [[RapeAsBackstory against their will]]]].

* Inverted in ''ComicBook/{{Empowered}}''. Empowered and her boyfriend Thugboy are both very hot, and are constantly shagging. Their flatmate, the AmbiguouslyBi Ninjette, admits that she can use the sexual frustration created by their failure to have sex with her to boost her ninja magic.

* In the second ''ComicBook/{{Sasmira}}'' book, it's revealed that Stan and Bertille inadvertantly performed the time travel by having sex in a pyramid during summer solstice. [[spoiler: They have to do it again in Kheos pyramid in order to return to their time.]]

* ''Literature/AnitaBlake'' and ''Literature/MerryGentry''. Both Creator/LaurellKHamilton series feature a protagonist who can cast great works of magic through sexual acts. The only difference is, Anita Blake is part-succubus and Merry Gentry is half-fae.

* ''Eros and the Mysteries of Love'' by Italian fascist philosopher Julius Evola is basically a catalogue/explanation of historical sex magic ranging from ancient babylon to Aleister Crowley.

* ''Literature/TheSpellmongerSeries'': The first book ends with a literal bang, as the main character and his Ex have sex to power a giant spell to forcibly bridge two location in the fabric of space and time, in order to save the population of the valley from a horde of genocidal goblins.

* "The Witch of the Westmoreland" by Archie Fisher features a knight with a WoundThatWillNotHeal seeking the title witch to cure him. She does so, and grants him invulnerability to boot.

* 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.

** A Third-Party published supplement, called ''Nymphology: The Book of Blue Magic'', was exactly what it said on the tin. The entire book, from front to back was dedicated to this trope, dealing with the aforementioned "Blue Magic" school of magic, and including new prestige classes, spells, and the like to get this most out of this particular type of magic. Though, unlike ''Erotic Fantasy'', ''Nymphology'' was played more for gross laughs, even if it had a few decent ideas.

* ''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.

* Cleopatra in ''WebAnimation/UnbiasedHistory'' was portrayed as using the Julian seed from her romps with Julius Caesar to mind control Mark Anthony and feed her ambitions of power against Octavian. As the latter prevailed and became Caesar Augustus, his wife Livia used his seed as a means to off his potential heirs until he'd have no choice than to choose her son Tiberius.

** One of the fan-created supplements written under the Open Game Licence for the UsefulNotes/D20System was the ''Book of Erotic Fantasy''. It contains extensive rules for all things sexual, including a number of spell-casting [[CharacterClassSystem classes]] who rely on sexual activity to use their magic, a selection of spells unique to them that require having sex to cast, and feats for using sex to enhance one's body and mind.

Some wizards use wands and ritual implements to cast their spells. Some use [[IKnowYourTrueName True Names]] or a LanguageOfMagic. Some invoke extraplanar beings. Some use MagicMusic. And then there's ''these'' spellcasters, who wield magic through sexual acts. The sex acts might be a way to raise or transmute power, or could be done as part of invoking TheLawsOfMagic (specifically the Laws of Association and Contagion) on the mage's partner.

* ''Eros and the mysteries of love'' by italian philosopher Julius Evola is basically a catalogue/explanation of historical sex magic ranging from ancient babylon to Aleister Crowley.

* Cleopatra in ''WebAnimation/TheUnbiasedHistoryOfRome'' was portrayed as using the Julian seed from her romps with Julius Caesar to mind control Mark Anthony and feed her ambitions of power against Octavian. As the latter prevailed and became Caesar Augustus, his wife Livia used his seed as a means to off his potential heirs until he'd have no choice than to choose her son Tiberius.

* In Christianity and Judaism, sex unites two people (a man and a woman) as "one flesh", which is why God only permits sex to be done within monogamous heterosexual marriage, and Paul the apostle refuses to join "the members of [Jesus] Christ" with a harlot.

* ''Literature/SwordOfTruth'': In ''Stone of Tears'' it's shown sorceresses and wizards can get each other aroused with magic, or it's implied enhance the experience while having sex. Jedediah uses his magic to arouse a sorceress this way, and before he has sex with her ([[SexyDiscretionShot off page]]) one does the same for him as well.

* ''Eros and the mysteries of love'' by italian philosopher Julius Evola is basically a catalogue/explaination of historical sex magic ranging from ancient babylon to Aleister Crowley.

* ''Literature/WildCards'': Fortunato's powers are based on, and charged by, Tantric sex.

* 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.

** In ''VisualNovel/{{Tsukihime}}'', the twins Kohaku and Hisui are "Synchronizers" who carry large amounts of {{Mana}} that can be transferred to others, [[spoiler:which has the side effect of suppressing the [[InTheBlood "inversion impulse"]] in those with demon ancestors]]. For most of the story they use this ability by allowing others to drink their blood, but if Shiki becomes close enough to one of the twins he can have sex with them for this purpose. In the BackStory, [[spoiler:this transfer was carried out [[RapeAsBackstory against their will]]]].

* ''Literature/StrangerInAStrangeLand'': Sleeping with Michael (the protagonist who has PsychicPowers from being raised by StarfishAliens) will allow the person to duplicate his powers, including AstralProjection, telekinesis and causing things to cease existing.

* ''Fanfic/WanderingPilot'' plays this straight and inverts it. [[Anime/NeonGenesisEvangelion Shinji]] gains [[WhiteMage healing abilities]] [[PowerPerversionPotential that make the girls of]] ''Anime/QueensBlade'' [[ThePornomancer 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 in one occasion he gets captured and raped by [[SlimeGirl Melona]].]]
* In ''Fanfic/TheStanfordAdventureClub'', you have a demigoddess and half-fae popping their cherries in a cave full of ley lines, with evocation of the four elements. The result is a ''coast-wide springtime'' and general horniness amongst the populace.

* It is heavily implied in ''Manga/NegimaMagisterNegiMagi'' that forming a Permanent Pactio between two people requires them to have sex.

* A 2006 Australian update of ''Theatre/{{Macbeth}}'' has the title character as a crime boss and the Three Witches as goth schoolgirls. Macbeth has sex with them during the fortune-telling scene. No doubt [[{{fanservice}} other interpretations of the play have done the same]] whenever [[ AdaptationalAttractiveness the witches aren't portrayed as bearded hags]].

* 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 SexMagic 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.

* Among many other forms of magic, witches from ''Comicbook/TarotWitchOfTheBlackRose'' partake in sex magic. Especially appropriate, given the [[BestKnownForTheFanservice high count of naked women]].

* ''Spells and Androids: The Joy of Sex'', an ''{{Series/Andromeda}}''/''{{Series/Charmed|1998}}'' crossover fic, has Phoebe appearing aboard Andromeda after some scrying spell goes wrong. Sex Magic turns out the only type available to send her back to her time before she's stuck in the future permanently.

* Given the use of sexual imagery when Willow and Tara are spellcasting, as a GettingCrapPastTheRadar of hinting at their lesbian relationship, this naturally figures in ''Series/BuffyTheVampireSlayer'' SlashFic. And not just Willow/Tara either. In ''The Fog of War'' by Kitty Karnivore, a magical accident leaves Buffy and Spike spellbound, so they have to reverse the spell through 'ritual' means. When Buffy has a look at the pictures in the spellbook, she immediately accuses Spike of having set up the whole thing on purpose.

* Season 4 of ''Series/BuffyTheVampireSlayer'' used spellcasting as a [[GettingCrapPastTheRadar 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 "[[IsThatWhatTheyreCallingItNow 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]].

* "Sex Magick" by Satanic doo-wop band Twin Temple is part IntercourseWithYou, part up-beat HollywoodSatanism.

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 his 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.

* It's strongly implied in ''Film/Ghostbusters1984'' that this is how Louis (possessed by the Keymaster) and Dana (possessed by the Gatekeeper) summon Gozer.
* The Temple of the Four Orders from ''Film/SherlockHolmes2009'' apparently practices this [[spoiler:(or tries to: their "magic" is all mundane stage magic)]], as villain Lord Blackwood was "conceived during one of our rituals".

--> ''*Abigail... You don't have to do this... there are other ways...*''
--> "Oh, but Master! You know how being among the Dead and Dying affects me! Now enough of that!" She initiated coitus in the ninth position of the Kama Sutra, 'Chakrabandha, the Wheel'. As they howled the N'thargo Chant in unison to their coupling, and their victims moaned, and the Synchronic Infindibulator tinkled and droned, the ship slipped into the solid wall of flashing mist, and disappeared from the sight of Lady Jettatura's yacht.

--> “Every time [my followers] have sex and orgasm, I get a jot of magical power from it, as though they’d performed a tantric sex ritual. It’s a byproduct of the act that would normally go to waste.”
