->''"Som say no evil thing that walks by night\\
In fog, or fire, by lake, or moorish fen,\\
Blew meager Hag, or stubborn unlaid ghost,\\
That breaks his magick chains at curfeu time,\\
No goblin, or swart faery of the mine,\\
Hath hurtfull power o're true virginity."''
-->-- '''Creator/JohnMilton''', ''Theatre/{{Comus}}''

So you've got your hands on a spiffy, brand new bunch of AppliedPhlebotinum. It will do ''anything''. Launch psychic fireballs, generate matter out of nothing, lay waste to entire towns, fulfill your fondest desires, and [[FlightStrengthHeart let your cat out every evening before bedtime.]]

There's only one catch: the person using it has to be that rarest of all rarities in a normal, functioning, sex-obsessed adult society.

[[NatureAdoresAVirgin A virgin]].

And by virgin, we mean a ''[[AlwaysFemale female]]'' [[DoubleStandard virgin.]]

And by female virgin, we generally mean a sweet, young (but adult), [[TheIngenue beautiful, innocent, passive, wholesome]] virgin. The ActionGirl is treated as something of a subversion, as is an actual prepubescent {{child|renAreInnocent}}, a [[HollywoodHomely not-so-conventionally-attractive]] young woman, and the sour-tempered and ancient OldMaid is always played as if it were a subversion.

And just why would someone need to be a virgin to have access to a special power? Most likely because [[SexIsEvil being a virgin is a generally recognized sign of moral purity]]. When played completely straight, this trope associates (female) virginity with moral purity and implies a MadonnaWhoreComplex; because of this, more modern invocations of this trope specify that it is merely a [[FunctionalMagic magical rule]] or the preference of a particular divinity rather than a value judgment.

Sometimes this ideal of purity can be subverted by having the virgin user of the AppliedPhlebotinum be [[AntiHero morally reprehensible in every other aspect of her life]], or even be a ''villainess'' instead of a heroine.

If the user of the Virgin Power is the hero's girlfriend, you can expect this situation to create a lot of dramatic tension between the lovers, as they fight the temptation to do the ''[[CantHaveSexEver one thing]]'' which will render her powers useless. Also, you can expect the villains to try to "relieve" the user of her virginity via rape [[WhyDontYouJustShootHim (even when just killing her from a distance would be the safer and faster option]], unless the power in question doesn't allow for this).

EunuchsAreEvil can be a villainous version, if such a character has special powers that come with the position, although most eunuchs are not celibate by choice (and in some cases, sex may still be possible after castration). Contrast DeusSexMachina. Beware VirginSacrifice. Tends to cause VirginTension. A SubTrope of ConditionalPowers. VirginVision is ''not'' related to this trope, regardless of how it sounds. The inverse is SexMagic, which is magic powered '''by''' having sex.



[[folder:Anime and Manga]]
* ''Manga/FushigiYuugi'' had both Miaka and Yui's powers tied to their respective virginities. Of course, the series milked the romantic tension this generated for all that it was worth. Both girls also underwent rape-related subplots as well. This leads to Yui's believing herself to be both a virgin and a rape victim simultaneously. [[spoiler: She was never raped. She just lost consciousness before things turned really ugly and didn't know she was rescued before anything happened to her. Unfortunately, her rescuer used her state of trauma to manipulate her for his own purposes. Also, she didn't know about the virginity part of the equation.]]
* ''Manga/PleaseSaveMyEarth'' - the Kiches Sarjalian, who can talk and sing to plants, lose their powers upon losing their virginity. Lots of sexual tension. Subverted when [[spoiler:Moku Ren keeps her powers even after she's raped by Shion, which causes a huge misunderstanding that's the reveal behind the entire plot.]] [[spoiler:Mokuren is a special case though, all other Kiches Sarjalians, including her parents,]] really do lose their power once they aren't virgins. And yes, there are male virgins with special powers too (rare as they are)!
* ''Anime/DevilHunterYohko'' features a heroine who must remain a virgin until she gains her powers. (Her mother was unable to fight temptation and thus, could not become a demon hunter.) Interestingly, once Yohko gained her powers, she no longer needed to remain chaste, as her [[IWantGrandkids grandchild-wanting mother]] hastily and happily informed her. A later episode make it waffle on weither or not she has to maintain her virginity after all.
* ''Anime/MaiOtome'', in that the {{Nanomachines}} that power the Otomes become worthless if they have sex through some convoluted biochemical reaction. While this is moot for some characters who choose their powers over relationships or some who do otherwise (Akane and Kazuya seem adamant about getting together, although they comically never succeed) it's a bit of FridgeLogic why they couldn't just use protection (if the condom breaks... Yikes!). Most fans don't think about it, aside from the cynical suspicion it's part of the {{Moe}} fandom's obsession with virgins.
** Interestingly, the requirement doesn't actually forbid sex, but ''heterosexual'' sex. Since the problem with the Nanomachines (and the reason for which men can't be Otomes) is that they can't cope with an Y chromosome (Not like they ever explain ''that'', though). So in other words, lesbian sex would be totally alright. Talk about excuses for SituationalSexuality!
** Another explanation in-series links this to [[VoodooShark Prostate-Specific Antigen, which destroys the Otome nanomachines on contact]]. This is a major research flub, since [[YouFailBiologyForever it is also found in female bodies]]. It isn't explained if this means that the nanomachines are able to resist low levels of PSA, or require special agents that have been genetically modified to produce better conditions for bioenhancement.
* ''Manga/KamikazeKaitouJeanne'':
** Maron's powers follow this trope right down to the [[spoiler: rape assault by a major villain]] however it subverts it in the end by [[spoiler: revealing that Maron can indeed use her powers after being deflowered, because her soul is still 'pure']].
** This also comes up when Jeanne travels back in time [[spoiler:and meets herself in a previous life as UsefulNotes/JoanOfArc. She tries to help Joan escape from being burned at the stake but Joan cannot become Jeanne anymore because she'd already been raped.]]
* Janine from Animerica truly believes that [[TrueLovesKiss kissing is the ultimate form of showing one's true love for another...]] [[spoiler:Too bad she gets raped by the BigBad afterwards...]]
* Mentioned, but averted, in ''LightNovel/{{Slayers}}''. At one point, Lina Inverse says that it's a common myth that if a sorceress loses her virginity during her [[spoiler: menstrual period, when her powers are the weakest]], she'll lose her powers forever. She then says that this is an untrue myth in the next sentence.
* In ''Manga/{{X1999}}'', [[spoiler: [[DefrostingIceQueen Arashi Kishuu]] loses the power to summon her CoolSword after she loses her virginity to her boyfriend, fellow Dragon of Heaven [[ShockAndAwe Sorata Arisugawa]].]] Also, it's pointed out in the CD dramas that [[spoiler: Arashi's MissingMom went through the same process.]]
* ''Manga/{{Hellsing}}'':
** In both the manga and OVA versions virgins drained by a vampire become vampires themselves, while non-virgins are turned into mindless zombie-like ghouls ([[spoiler:though it becomes a plot-point when even children and other obvious virgins are found as ghouls instead of vampires]]). This is why, in the first chapter/episode, Alucard asks if Seras is a virgin [[ShootTheHostage before...]]
** Also, some characters remark that virgin blood tastes better; at one point, the BigBad asks that the first paratrooper to land in the final battle be given virgin blood as a reward.
* In ''Manga/{{Bastard}}!!'' the only way to transform [[NonActionGuy young and meek Rushe Ren-Ren]] into his other self, the ultra powerful [[HandsomeLech (and ultra perverted)]] Dark Schneider, is to perform the "Accept" spell, where a young virgin kisses him. Usually, this is his best friend Yoko. When it doesn't appear to be working the first time they tried it, Yoko's father asks whether she really is one, and is met with a thrown shoe and an assurance that "This girl's chastity is a hun- ''[[TechnicalVirgin eighty]]'' [[TechnicalVirgin percent perfect]]." It ''does'' kick in a few seconds later, so maybe she has a point...
** Pops up again when a vampire decides to feed on the captured Princess' [[AmazonBrigade guardian maidens]]. He notices by taste that one of them was not a maiden after all.
* In ''Manga/KannazukiNoMiko'' Himeko Kurusugawa and Chikane Himemiya are virgins until [[spoiler:Chikane rapes Himeko]]. The point of which in the anime was [[spoiler:as part her StrikeMeDown plan to make Himeko kill her]] but in the manga it was meant to [[spoiler:remove her powers through the loss of her purity, thus making her worthless as a sacrifice to the Orochi, but it's subverted by the use of Himeko's hymen-blood to revive Ame No Murakumo, since that blood is technically pure]].
* ''Manga/KoeDeOshigoto'' has a particularly ironic example, as virgins make the best eroge voice actors, because sex in real life is nothing like its portrayal in games. Fumika is not happy about her lack of hands-on experience.
* ''Anime/GhostInTheShellStandAloneComplex'' uses this in ''2nd GIG'' when [[spoiler:it's revealed that Gohda created the Individual Eleven memetic virus, and made it only affect those who were virgins before being fully cyberized. Suddenly everything makes sense]].
* Inverted in ''Anime/PantyAndStockingWithGarterbelt''. [[spoiler: The last sign that Panty lost her angelic powers was that her hymen grew back, regaining her virginity. She gets her powers back when she has sex with Brief, breaking her hymen.]]
* It has been said in the ''LightNovel/HighSchoolDXD'' universe that unicorns will only approach virgins and they need the horn of the unicorn to [[spoiler: get Rias and Asia back to normal because they've been turned into children.]] While all of Issei's harem are virgins, Azazel uses Akeno as bait for the unicorn. [[spoiler: [[HilarityEnsues She then smacks the unicorn, knocking it out and take the horn of said unicorn]]]]
* ''Manga/MariaTheVirginWitch'': If Maria loses her virginity, she loses her powers.
* In the hentai ''Bible Black'' a particular ritual performed by a cult was supposed to require a VirginSacrifice. Unfortunately the leader of said cult didn't watch her cronies closely enough and they raped the poor girl, which is implied to be the reason the ritual went horribly wrong. When [[spoiler:Kitami, who was the victim the first time around]] tries the ritual again years later she doesn't make the same mistake and gives her chosen sacrifice a chastity belt to prevent this from happening again.
* D's in ''Anime/UnlimitedFafnir'' lose their powers in one of two ways: Aging to 20 or so and pregnancy. The closest we've seen to the former is Haruka Shinomiya who was a D and has since lost her powers and Kili Surtr Muspelheim who is at most in her late teens and nearing that point [[spoiler: before Yuu makes her his "mate", which leaves her control of dark matter in the future uncertain]]. No pregnancy related loss of powers have been shown so far.
* In the hentai ''La Blue Girl'', in a rare male example, semen from a virgin can be used with a particular spell (and consumed) to get the kunoichi that uses it to the Shikima realm. (No word on whether or not a male ninja could use this technique with another male, or by consuming the vaginal secretions of a female virgin.)
* Possibly occurs in ''Anime/YukiYunaIsAHero''. It's stated that only "pure" girls can become [[MagicalGirlWarrior Heroes]]. It's never elaborated what exactly "pure" means, whether it be "pure hearted" or what. Only elementary and secondary school aged girls are shown as Heroes.
* ''Anime/SpeedGrapher'': Kagura Tennozu, the female protagonist, has to be chaste and pure to develop Euphoria virus/powers as "[[SuperEmpowering The Goddess]]". During the time she's a captive of Suitengu and the Tennozu Group (before and after being rescued by [[TheHero Saiga]]), she's given chemical substances to delay her growth and postpone her first menstruation, which will result in the loss of her powers (presumably because once puberty happens she'll have sex).

[[folder: Comic Books]]
* ''ComicBook/TheDarkness'' series has this to a certain extent. While Jackie was not a virgin before his 21st birthday, he later learned that having sex with a woman would kill him, because the Darkness (and his life by extension) would leave once his sperm fertilized an egg. It should be noted that this revelation caused him almost as much distress as the people who were trying to kill him when he found out. There is, however, a loophole; [[spoiler:the Darkness itself possesses him and rapes the comatose Sara Pezzini, bearer of half of the Comicbook/{{Witchblade}}. The {{NSFW}} [[http://i67.photobucket.com/albums/h291/SirThinks2Much/scansdaily/sejic/jackiesex.jpg art]] implies that they or their...riders were both conscious of it on some level, [[UnfortunateImplications but still]]. Please note that neither Jackie nor Sara has any memory of the conception.]]
* The last arc of ''[[ComicBook/JusticeSocietyOfAmerica JSA]]'' before its reboot got a certain amount of use out of Courtney Whitmore (Stargirl) being a virgin -- more specifically, it meant she was unaffectable by the ghost villains the team had to deal with that week. Oddly, this story wasn't written by Geoff Johns, the character's creator who based her on his little sister -- it had more to do with her being the only teenage girl on a team consisting mostly of adult males. Interestingly, the only teenage male on the team did not have the same advantage...
* For ''ComicBook/AlphaFlight'' member Snowbird, losing her virginity had mixed results. She lost her immortality and, for a time, the blessing of her family, but she gained the ability to leave Canada's borders without ill effect and could change into any animal rather than just those native to the North. She herself didn't think much of the benefits for a very long time, but her teammates did, as they previously had to do without her power whenever a mission took them away from Canada.
* Subverted in ''LegendsFromDarkwood''. The main character, Raynd, remains a virgin for the purpose of hunting unicorns and selling their delicious meat at a premium.
* In the French comics series "Epic of the Dragon Knights" (la geste des chevaliers dragons). In that world, dragons turn any creature that gets close to them into a crazy monster. The only people not affected by this evil power are virgin women. So, the knights' order specially set up to kill dragons is only female, with ActionGirl virgins.
* Lampshaded in ''ComicBook/TopTen: The Forty-Niners'', where an officer is grousing about how the whole thing is just a ploy by the heroines.
* Variant in ''Comicbook/{{Empowered}}'' -- the "Seiseiryoku-henkan-sentou no jutsu" transforms sexual frustration into fighting power.
* In ''Le Collège Invisible'', only "pure maidens" are immune to Dragons'/Great Destroyers' zombification aura. Well, pure maidens and [[AntiMagic Néga-mages]], the latter also protecting nearby allies.
* Both ComicBook/WonderWoman and ComicBook/{{Supergirl}} are sometimes called "The Maiden of Might". Both of them would probably still have their powers if they ever stopped being a virgin -- although Wonder Woman's association with the virgin goddess Diana might cast some doubt on this -- but they'd clearly have to drop the "maiden" appellation.

[[folder:Fan Works]]
* In the Franchise/HarryPotter fic ''The Problem with Purity'' any witch or wizard who was still a virgin at the age of seventeen became a "Pure Adult" and both they and their first sexual partner received a power boost immediately after copulation. Also, only a Pure Adult could have a magical animal as their Animagus form.
* In the Creator/AAPessimal's ''Literature/{{Discworld}} Tarot'' chapter ''[[http://www.fanfiction.net/s/6697660/24/The-Discworld-Tarot The Ace of Swords]]'', there is a [[LesYay different twist]] on this trope. Miss Alice Band is able to tame a rogue unicorn where others have failed, despite being sexually experienced. The reason Alice gets away with it is because her sexual experience is ''only'' with other women. She still technically qualifies as a maiden, unsullied by contact with men, and therefore fully meets the strict specification for unicorn-wrangling - because she has ''never'' had contact with men. It is possible that while the unicorn was trying to make its mind up as to whether she qualified, she got a silver-ornamented bridle over its head and settled the question definitively.
* In ''[[http://www.fanfiction.net/s/7010227/3/Emancipation Emancipation]]'' it's impossible for a virgin witch or wizard to be raped or molested. Virginity has to be given up willingly or not at all.
* ''FanFic/ABrighterDark'': In order to cast a hex that will spread disease among the Chevois rebels, Odin needs, among other things, the tears of a maiden. This leads to the amusing revelation that [[spoiler:Felicia is not a virgin]].

* ''Film/ConanTheDestroyer'' had a princess whose virginity was apparently necessary for her to handle a sacred relic without harm. (Of course, the real reason she needed to remain pure was so that, at the end of the movie, she could become a VirginSacrifice to the god to whom the relic belonged.)
* Subverted in the movie ''Film/KullTheConqueror''. The hero's non-virgin love interest needs a god to grant her the power to destroy the BigBad. She knows gods usually don't hand that kind of power to non-virgins, so she asks the god to give it to her anyway, since her ''intentions'' are pure at least. The god generously obliges. It perhaps helped she lost her virginity as [[ScarpiaUltimatum a price]] (yep, the old king was one dirty ol' bastard) for letting her brother free (he was to be executed for heresy), and not by just screwing around.
* In the Film/JamesBond film ''Film/LiveAndLetDie'', Solitaire's fortune-telling ability is linked to her virginity. Bond relieves her of both, which caused some controversy among the audience (especially as he tricks her into it).
* Virginity ''seems'' to be a requirement for the sorcerers that serves the King in the movie ''Film/TheScorpionKing'' [[spoiler:... but at the end of the movie the sorceress informs the title character that it was simply an effective way of getting their masters to keep their hands off.]]
* ''Film/HocusPocus''. The candle that will bring the witches back to life can be lit only by a virgin. Once everything's been set right in the end, the ghost Thackery and his waiting sister Emily walk towards the afterlife casually conversing about what on earth took him so long. Thackery coyly replies that he had to wait three centuries for a virgin to come along and break the curse. It's especially funny because the virgin who lit the candle WAS A DUDE. How many 8-year-olds didn't get ''that'' joke the first time around?
* Inverted in ''Film/OnceBitten'', where the male lead needs to lose his virginity to protect himself from the vampiress. He just barely "makes it" in time. But he didn't have time to enjoy it, which is probably why they went right back to it at the end.
* ''Film/TheMonsterSquad'' has an amulet that, through the reading of a magic spell that works only if the reader is a virgin, blows a hole in Limbo to suck the monsters into it. Dracula wants the amulet because every hundred years, the amulet becomes vulnerable enough that it can be shattered. The titular bunch of kids first try it out with Patrick's sister, only to find out that she's not a virgin because of a one-night stand, so they have to have Sean's sister, five-year-old Phoebe, read through the spell with the help of Scary German Guy.
* In ''Film/BirthRite'', Rebecca, a virgin, has to have sex with a warlock in order to gain her "birth rite" as the grand dame, but can't have sex with anyone else, to avoid becoming impure. She ''does'' have sex with her adopted brother, and then kills him in order to rectify her sin.
* ''Film/CastADeadlySpell'' has "the last unicorn hunter" who is also intended as a virgin sacrifice to the Old Ones. There's a lot of drama around the obvious and anticlimactic solution.
* ''Film/{{Stardust}}'' subverts this. The reason Yvaine can ride a unicorn is less because she's a virgin than because she's a ''star'', and because the moon, Yvaine's mother, specifically sent the unicorn to protect her. Although in the book, it's mentioned the unicorn doesn't want Lamia to come near it, but that because she's evil and out to kill the star that the unicorn was sent to protect.
* Subverted in ''The Mistress of Spices''. A woman from India with the power to use magical spices is forbidden to touch any of her customers (including making love to them). She violates the rule by falling in love with a man and is punished by the spices for doing so, so she atones by setting herself and her spices on fire. She survives, and learns that because she was willing give up everything for the spices, she no longer has to follow the rules.
* Subverted in ''Film/JennifersBody''. The ritual is supposed to be performed on a virgin, and Jennifer is, well, not.
* ''Film/{{Legend 1985}}''. Lily's "innocence" allows her to approach the unicorns. This is deliberately taken advantage of by Darkness and the goblins to harm them.
* It would seem in the ''Franchise/FridayThe13th'' franchise, an innocent, virginal girl has a much better chance of surviving than anyone else. With a few exceptions [[spoiler:(Megan in [[Film/FridayThe13thPartViJasonLives the sixth movie]], Jessica in [[Film/JasonGoesToHellTheFinalFriday the ninth]], and ''maybe'' Ginny in [[Film/FridayThe13thPart2 the second]]]]), the FinalGirl has always qualified.
* As a parody of Slashers, ''Film/TheFinalGirls'' has virginity as a plot device since only a virgin gets to be the Final Girl who kills the villain.

* Every ActionGirl in ''Literature/TheFaerieQueene'' is also a virgin, who conveniently comes across a sorcerer or monster (representing various lusts) who can be defeated only ''by'' a virgin. ''Of course'' a poem written in honor of UsefulNotes/ElizabethI, aka ''The Virgin Queen'' of England, would be populated with ass-kicking virgins!
* OlderThanPrint: The 12th century epic poem ''Literature/{{Nibelungenlied}}'' has the character Brunhild, Queen of Iceland, whose virginity gives her superhuman strength (she can throw 22 metres a boulder that takes 12 men to lift).
* ''Literature/IncarnationsOfImmortality''
** Played with in ''Literature/OnAPaleHorse'' when Luna, despite having been the victim of MindRape and soul tarnishing by a demon, is still technically a physical virgin, so she is acceptable food for a hungry dragoness.
** In ''Literature/ForLoveOfEvil'' when Parry (a young sorcerer) is about to marry Jolie (a stunning, brilliant woman due to her ability and Parry's training), someone drives a unicorn into the bridal party, but Jolie is able to call and touch the unicorn, proving she is still a virgin (and stunning her father and the entire town).
* Lightly subverted by Creator/MercedesLackey in the ''Literature/{{Tales of the Five Hundred Kingdoms}}''. A female virgin attracts male {{unicorn}}s (and vice versa), but {{unicorn}}s on the whole are fawning, brainless creatures that just get in the way. Most "post-virgins" don't regret their absence.
* ''Literature/ManyWaters'' by Madeleine L'Engle has the {{unicorn}} thing. Interestingly, the book centers around two male virgins (although a big deal isn't made about it).
* In Creator/AlanDeanFoster's ''Literature/{{Spellsinger}}:''
** A young girl is hired by some bandits to lure out a unicorn stallion, who is entirely unaffected (beyond being friendly and protective towards her, at any rate) because he's gay.
** The protagonists rescue a DistressedDamsel from pirates, only to get captured by a tribe of [[ItMakesSenseInContext morbidly-obese fairies]]. The fairies claim that bathing in a virgin's blood is a possible cure for their condition, but their plan is scuttled when the girl, upon hearing their intentions, collapses in a fit of uncontrollable, pants-wetting laughter.
* In Creator/CarolineStevermer's ''Literature/AScholarOfMagics'', [[spoiler:the Agincourt Device, which can turn people into animals, doesn't work on virgins -- one of whom, the viewpoint character and undoubted hero, is a very adult man]].
* Creator/TerryPratchett's ''Literature/{{Discworld}}'':
** Wizards are expected to remain celibate, because they believe sex messes with their powers. There is the suggestion that performing powerful magic is just as much fun as orgasm. The book ''Discworld/{{Sourcery}}'' reveals the true reason -- every male child of a wizard is a born a wizard and the ''eighth'' male child born to a wizard is a "[[PersonOfMassDestruction sourceror]]" (a wizard "squared"), with ''very'' [[TheEndOfTheWorldAsWeKnowIt bad results]] for the Literature/{{Discworld}} as a whole. Luckily, wizards are generally the kind of geeks who would have difficulty attracting women anyway. (As the ''Literature/{{Discworld}} Companion'' puts it, if magic cared whether or not you're a virgin, [[ReallyGetsAround Nanny Ogg]] would be a washerwoman.)
** Literature/{{Discworld}} also [[PlayedWith plays with]] the {{unicorn}} myth. Granny Weatherwax demonstrates that the virgin need not be young or innocent.
* ''Literature/TheDresdenFiles'':
** Played with in the case of Warden Ramirez. He constantly plays himself as a great ladies' man, to Harry's annoyance. However, when they work with Lara of the White Court (think vampire succubus who feeds on sex), she looks at Ramirez, smiles and says "Oh, you've brought me a treat", since she is clearly detecting his virginity. Virgins are apparently the tastiest sex food for them.
** In the short story "Heorot", the grendelkin kidnaps a young virginal bride with the intention of impregnating her. According to Gard, such creatures are an all-male species that can't reproduce except with virgin women.
* Subverted in Creator/ElizabethAnnScarborough's ''Literature/TheUnicornCreed'', where a "household witch" (magical cleaning, cooking, etc.) has to ''lose'' her virginity when she's 18 or she will lose her powers. Also, unicorns associate with virgins because they're young, impressionable, and it lasts only a short while (unicorns are out to make the world a better place, one girl at a time). It is stated that they could have chosen pregnancy just as easily, except you can get pregnant more than once.
* In Creator/TheodoreSturgeon's short story "The Silken-Swift", the unicorn subverts this trope itself. Given a choice between a gentle young woman who'd recently been raped, and the virginal witch who'd maliciously (though indirectly) caused the assault to happen, the unicorn chooses to lay his head in the lap of the true innocent (who promptly sets it free).
* Phyllis Ann Karr's ''Literature/FrostflowerAndThorn'' duology features a society of sorcerers who believe they can work magic only if they're virgins. This applies to women ''and'' men. (They tend to adopt a lot.) However, Frostflower the sorceress survives a rape without losing her powers, which suggests that this particular teaching is at least oversimplified.
* The whole "virgins and unicorns" theme was played with a little in ''Literature/HarryPotterAndTheGobletOfFire''. After Hagrid was [[OldShame too ashamed to show his face]] after being exposed as a half-giant, the substitute assigned to teach his class brought a unicorn to the class -- warning the students that it would only let the girls touch it. (True, it's likely that the male students were virgins too, given their age, but unicorns are even more picky than usual.) Hagrid later one-ups her by getting some unicorn ''foals'' that the whole class can pet and examine, explaining that they only grow hostile to men toward adulthood.
* In Creator/MarionZimmerBradley's ''Literature/{{Darkover}}'' series, only virgin women can harness maximum psychic powers and become "Keepers." Basically by not channeling their energy into sex, they have far more psychic power available. In the darker days some Keepers were psychologically and even physically castrated so they could not engage in or even think about sex even if they wanted to. Psychological blocks against sexual activity are actually major plot points in at least two of the Darkover books. (But that probably a different trope.) A lot of the problem was cultural; an almost religious importance was attached to the idea of the Keepers as sexless virgins, and more than one person died for saying that it didn't have to be that way.
* A subversion in Creator/HarryTurtledove's short story ''Honeymouth'': The foul-mouthed and very lecherous mercenary, ironically dubbed Honeymouth, is somehow able to ride a unicorn without any problem. When asked how he can do it, usually while the unicorn is parked outside a brothel, he sarcastically replies that he's a virgin. [[spoiler: He is, technically. The nickname "Honeymouth" has nothing to do with scatological verbiage.]]
* Creator/ElizabethBear's Matthew Szczgielniak is another male example, at least for most of the first two books in which he appears--the first of which, ''[[Literature/ThePrometheanAge Blood and Iron]]'', also features a particularly {{Grimmifi|cation}}ed take on the Unicorn Thing.
* In Creator/FredSaberhagen's ''Empire of the East'' and ''[[Literature/BookOfSwords Swords]]'' series, some wizards, both male and female, lose some or all of their power if they lose their virginity. Many do not, and, indeed, some are quite promiscuous with no ill effects, but there is no explanation of why some do and some don't.
** More specifically, in ''The Second Book of Swords'', Doon and Mitspieler are very intent on Ariane maintaining her virginity, [[spoiler:because they plan on sacrificing her to a demon.]]
** And in ''The Third Book of Swords'', Kristin gives up her virginity [[IntimateHealing to save Mark]] from his poisoned wound.
* Confusingly used in Creator/AndreNorton's ''Literature/WitchWorld''. Everyone believes that the witches lose their powers with their virginity, and it's proven to be true (one of the nastier enemies of the witches rapes the ones he catches for that very reason). However, most of the main female characters end up keeping their powers, even through several children. The books never address it explicitly, but all the cases where the woman keeps her powers has her having sex with a man who ''also'' has powers (unheard of in the land where the early books occur) and in at least some cases, their powers ended up somehow linked. The sole exception being Elys. Jervon explicitly does not have any sort of magical power, which is what caused half the trouble in ''{{Songsmith}}''. Gillan may also be an exception, considering the kind of power her husband has. Consensuality may have something to do with it, as may the expectation that you will lose your powers.
* In Sharan Newman's novel ''Literature/{{Guinevere}}'', a retelling of the Arthurian legends from the future queen's point of view, Guinevere has a telepathic link with one of the only remaining unicorns in Britain. At the end of the novel, she has married Arthur and has a final conversation with the unicorn, in which she discovers that -- oops -- she had to stay a virgin if she wanted the bond to continue.
* Guinevere has healing powers in ''Mad Merlin'', for which she must remain chaste. Three guesses as to how that turns out.
* In some versions of the Arthurian Legend, Lancelot has this power. He is the best and strongest knight because he is a virgin. Once he sleeps with Guinevere, he loses his strength. This is why he cannot reach the Holy Grail, but his son, Galahad, can. Galahad remains a virgin. (This of course leads to a very funny scene in ''Monty Python and the Holy Grail''.)
* In Robert Asprin's Literature/MythAdventures book ''Another Fine Myth'', Skeeve is the only one in the group that does not elicit a negative reaction from a [[strike:stolen]] adopted war unicorn, which gets him some teasing. This point was brought back in [[spoiler:''Sweet Myth-tery Of Life'', when Buttercup the unicorn acts unsociable towards Skeeve after he blacks out drunk on a date with a [[AnythingThatMoves vampire]].]]
* In John Barnes's ''Literature/OneForTheMorningGlory'', the goblin queen claims the goblins have raped a captive maiden. Gorlias says that would be impossible: trying to rape a pure maiden would have destroyed them.
* Creator/PoulAnderson:
** In ''Literature/AMidsummerTempest'', Prince Rupert is forced to bring Jennifer with him to a battlefield because he is traveling by magic, and the presence of a virgin is the only thing allowing the spell to be strong enough to travel that way.
** In ''Literature/OperationChaos'', Virginia had developed the magics that went with being a virgin. After her marriage, she had to retool her skills.
* Played for laughs in ''MakeWayForDragons''. The title character gets a fawning unicorn, who becomes more of a loyal dog than anything. Minor hilarity abounds as the other female characters have entirely distinct reactions to his being a virgin.
* The Creator/LarryNiven story ''The Flight of the Horse'' (AKA ''Get a Horse''). {{Time travel}}er Hanville Svetz is send to acquire a horse from the past, but can only find one with a horn, owned by a very young girl. Svetz doesn't even know what a horse is, let alone a unicorn. He buys the "horse" and takes it home where the only person who can handle it is "that frigid bitch Zera."
* In Creator/SimonRGreen's ''Literature/BlueMoonRising'', the lead character is a male virgin with a loyal, if sarcastic, unicorn. When he rescues a princess who ''can't'' ride a unicorn, the trio hastily agree that when they get back to civilization, the unicorn will have to "go lame": otherwise, it'd be far too embarrassing for ''both'' humans if he rides in and she walks.
* Played very straight in Angus Wells's ''Books of the Kingdom'' trilogy. The second book in particular focuses mostly on Wynett and Kedryn and the fact that they cannot be together unless Wynett gives up her powers.
* ''Gomez'' by Cyril Kornbluth: a young Puerto Rican maths/physics genius described as a 'second Ramanujan' is discovered in New York. He winds up in a super-secret research project that has been going nowhere, and comes up with a physical theory that implies the ability to create a super-weapon so deadly that he's horrified. The narrator, a sympathetic reporter, all but abducts the thoroughly stressed-out Gomez for a forced vacation; out of his sight, Gomez sneaks across a state line and marries his girlfriend. When he returns, his mathematical ability is (he claims) gone: he admits, with an glance at his (literally) blushing bride, that he now can't think about math at all.
* In Creator/StephenKing's ''Literature/TheStand'', Randall Flagg psychically forbids Nadine from having vaginal intercourse until she can join him and he can impregnate her. This doesn't stop her from fooling around with Harold every other way the pair can think of, so whether that's Virgin Power or just Flagg not wanting her to get pregnant by someone else first is unclear.
* In James [=MacDonald=] and Debra Doyle's ''Land of Mist and Snow'', Columbia Abrams can act as a BarrierMaiden because of her virginity. [[spoiler:Being an abolitionist, she doesn't on the whole approve of the imprisonment. And at the climax, she tells the hero of the story that their only safety is freeing it. Whereupon he, [[YouAreInCommandNow having just become captain]], declares them husband and wife, and they set up freeing it.]]
* In David Feintuch's ''The Still,'' the king/queen has the power to commune with his ancestors, which he uses to good effect to help run the country. The catch? He has to be a virgin. Unfortunately, the protagonist is a typically horny teenager. [[spoiler: Apparently, however, having sex with his male best friend doesn't "count" when it comes to losing virginity.]]
* K.A. Applegate's ''Literature/{{Everworld}}'' has a subversion of the idea that all girls are virgins. When they first see the [[PhysicalGod Greek Goddess of virginity]], Dionysus says to [[TokenGirl April]] "she'd like you." After a moment, he says the same thing to [[BlackAndNerdy Jalil]].
** At one point they also see a unicorn in the distance, and Christopher jokingly suggests that April wouldn't be able to attract it if she tried. April (who's very religious and, we later learn, explicitly waiting for marriage) tells him not to believe every rumor circulating around their school.
* A short story alternate history featured a psychic girl who helped the Nazis win WWII. After she runs away, meets the hero and they both get captured and taken back to Berlin, she asks him to 'depower' her. Also subverted as it implied this will have no effect on her powers but the fact that the Nazis ''believe'' her powers have been neutralised is enough.
* Subverted in Steven R. Boyett's fantasy novel ''Ariel''. The protagonist is a wisecracking twenty-year-old virgin, which allows him to become the magical Familiar of the eponymous unicorn. Though the unicorn delivers an occasional ass-kicking to the bad guys, she is [[spoiler:easily captured]]. Due to their [[strike:codependent relationship]] magical bond, the protagonist goes into unicorn withdrawal and becomes a bit of a headcase for the obligatory [[spoiler:rescue]] quest. The [[UnresolvedSexualTension constant advances from random women]] don't help, either.
* Literature/TheBible:
** A virgin brings the son of God into the world. It may or may not matter that she was a virgin; some denominations believe she was supposedly also born without original sin.
** In two male examples, her son, Jesus, and possibly (according to the apparitions at Fatima) her husband, Joseph.
** This is the case with many of the Catholic saints. St. Margaret of Cortona was an interesting one, in that Christ promised her in a vision that he would still honor her as a virgin in heaven even though she had a son before her conversion.
* Subverted in ''Literature/BlackDogs'', where only virgins are susceptible to the illusions of unicorns. The unicorns in question are mangy, carnivorous horse-like things that prey on those that fall to their illusions.
* King Math in the fourth branch of the ''Literature/{{Mabinogion}}'' cannot live unless he's either at war or has his feet in the lap of a virgin. Then Math's nephew Gilvaethwy gets the hots for the girl so his big brother Gwydion arranges a war to get Math out of the way. But the foot holder, Goewin, doesn't think Gilvaethwy is worth losing her job over so he rapes her. Against both princes' expectation Goewin confesses all to Math who comforts her, promises to make her his queen and then sets out to avenge both their wrongs on his unhappy nephews.
* An odd double subversion happens in Juanita Coulson's ''The Web of Wizardry'': Spellcasters—of at least a certain tradition—are strongly encouraged (but not necessarily required) to be chaste. However, when the hero and his witch love interest start having sex, it doesn't appear to affect her powers. Lira ''does'' start slipping a bit towards the end of the book...[[spoiler:but finally, she informs Danaer that this isn't because ''sex'' puts a strain on witches' magical ability; it's because ''[[BabiesEverAfter pregnancy]]'' does. It's implied that she'll regain at least ''some'' of her power after the birth.]]
* In the Creator/LisaShearin novel ''The Trouble With Demons'', Raine learns that a certain magical knife can only be located by a virgin. There turns out to not be all that many in the area, seeing as she's on a college campus. Especially since everyone knows that there are demons loose, and they'd all heard the rumors that demons went after virgins, and removed the risk to themselves in the most direct manner possible (This turns out to be pointless from a demon protection perspective - the demonology professor flatly states that even those demons that do care about virginity will still eat non-virgins if nothing else is available, and most of them will just eat anybody).
* In L. Jagi Lamplighter's ''[[Literature/ProsperosDaughter Prospero Lost]]'', one place where Creator/WilliamShakespeare diverged from fact is having Miranda married. She would have forfeited her virginity based powers.
* In Creator/GeorgeEliot's ''Literature/SillyNovelsByLadyNovelists'', she complains of a work supposed to be instructive because "the heroine [is] a Roman vestal".
* In ''Literature/ThePeshawarLancers'' universe, seers can only see the future while virgins. The thing is, eventually they start seeing the future constantly, driving them mad. The seer traveling with the hero eventually ends up begging the hero to take her virginity so that the visions will stop.
* Sort of inverted in Creator/UrsulaKLeGuin's ''Literature/{{Earthsea}}'' series where the main character is a wizard and a virgin, and notes only after [[spoiler:spending and permanently losing his powers]] that he never felt so much as horny while being a wizard. Apparently the two are linked inversely in his case. Other characters however have no trouble being both wizards and married. ''Sorcerers'' can be married or otherwise not celibate, but wizards can't. The magical hierarchy in Earthsea goes Witches* In ''[[Literature/TheObsidianTrilogy The Outstretched Shadow]]'' by Creator/MercedesLackey and James Mallory, Kellan asks the wild magic for an out [[spoiler:to escape the Outlaw Hunt]] and ends up meeting Shalkan, a unicorn who requires him to remain chaste and celibate ("you ''do'' know the difference?") for a year and a day. If Kellan breaks his vow, Shalkan threatens to [[spoiler:to remove Kellan's... parts... with his horn. Of course, Kellan doesn't think that keeping his sex drive under control will be a problem until he meets someone he's attracted to...]]
* Hinted at in Creator/CSLewis's ''Literature/TheVoyageOfTheDawnTreader'' -- it is a children's book, after all, but we are assured that "my little girl, she says the spell, for it's got to be a little girl or else the magician himself, if you see my meaning, for otherwise it won't work." Since Lucy qualifies, it doesn't mean a very young girl.
* In Gene Wolfe's ''Literature/BookOfTheLongSun'', only virgins can clearly see and hear messages from the gods. This serves as an in-universe justification for why priests and nuns are forbidden from carnal pleasures. Non-virgins can see and hear messed-up tidbits.
* In Jack Chalker's ''[[Literature/RiverOfDancingGods Dancing Gods]]'' series, the female protagonist starts out learning a form of magic that demands virginity. Naturally, once she's passed her tests she's instead taught a form of power [[DeusSexMachina based on prostitution]].
* In Creator/WilliamMorris' ''The Wood Beyond the World'', [[NoNameGiven the]] [[ExactlyWhatItSaysOnTheTin Maid]] explains to Walter that she will lose her powers when she loses her virginity, so they cannot have sex until after she has defeated the [[BigBad Lady]]. [[spoiler: She does. They do.]]
* A rare male example appears in Creator/JohnBrunner's "Imprint of Chaos", one of his ''Literature/TheTravellerInBlack'' stories. Eadwil, one of the diviners consulted by the Margrave of Ryovora, is a youth who's postponed "a major upheaval of his physiology", the better to preserve his prophetic abilities.
* In ''The Education of Jennifer Parrish'', a Satanic organization plans to switch the mind of one of their members with an innocent girl. The ritual requires that the victim '''not''' be a virgin, and one of their members is assigned to make sure of this but fails to do so. When the ceremony takes place, her virgin status foils the magic and saves her.
* The YA novel ''Rampant'' by Creator/DianaPeterfreund features a society of virgins who hunt bloodthirsty, evil unicorns. Over the course of that novel and its sequel, it’s shown that losing one’s virginity causes one to lose one’s ability to hunt unicorns—whether willingly (one girl sleeps with her boyfriend specifically to ''avoid'' getting roped into unicorn-hunting) or unwillingly (one girl is raped). Having sex with a girl doesn't count, fortunately for one couple. Losing one’s virginity likewise strips a girl of magical protection from the unicorns, who, albeit reluctantly, cannot attack a virgin. Also, males never (naturally) get either protection or powers, status of virginity notwithstanding.
* In ''[[Literature/PercyJacksonAndTheOlympians Percy Jackson]]'', the Hunters of Artemis are semi-immortal so long as they are virgins.
* Implied in one of the Literature/{{Xanth}} books; Mare Ann had the talent of summoning any kind of horse she wanted, and when she still had her "innocence", this included unicorns. She broke up with the Magician Humphrey because she wanted to keep that ability, but after her death she went to Hell, lost her innocence, and therefore is okay with being [[MarryThemAll one of]] Humphrey's wives again.
* In the novelization of ''Film/ConanTheDestroyer'', the princess ends up having sex with Conan on the way back to the city and her intended sacrifice. Bombaata, distrustful of Conan, asks the wizard Akiro to use his powers on Conan and Jenna to make sure she is still a virgin. Akiro replies that she is still pure. [[spoiler: He had earlier explained that "purity" is a matter of spirit, not of the flesh, and was being truthful, although not in the way Bombaata hoped.]]
* In Creator/JohnMoore's ''Literature/TheUnhandsomePrince'', the one-use-only magic spell that Rumpelstiltskin has for turning straw into gold requires the ''loss'' of virginity--which is why Rumpel is still looking for the ''right'' girl.
* Literature/TheGoodTheBadAndTheMediochre goes with the famous example where unicorns are attracted to young female virgins. Apparently, the standard method for hunting unicorns is to get a young female virgin to stand in the middle of a forest clearing and hide nearby with a gun. The heroes try to foil this when they find it happening by getting Charlotte - a young''er'' female virgin - to stand in a different clearing, thus attracting any unicorns ''away'' from the hunters. [[spoiler: It becomes a non-issue anyway, since the whole thing was a trap.]]
* TheUnmasquedWorld of Creator/KevinJAnderson's "Dan Shamble, Zombie P.I." novels came about when a drop of virgin's blood fell upon the Necronomicon under a full moon and during a rare astrological conjunction. A homely fifty-eight-year-old witch's blood, shed via a paper cut, but a virgin's nonetheless.
* In the Creator/StephenKing short story "The Mangler", blood from a virgin falling into a industrial laundry's speed ironer and folder, combined with some other things [[spoiler: causes the machine to be possessed by a demon]].
* In L. Jagi Lamplighter's ''The Unexpected Enlightenment of Literature/RachelGriffin'', the Vestal Virgins guard the powerful protection, the Eternal Flame. Violating their vows weakens it. [[spoiler:Rachel is shocked when one villain talks of how her grandmother's breaking her vows and how that strengthened those on the Dark Path.]]
* In the fourth book in ''Literature/{{Bloodlines}}'', a witch's power is halved when she loses her virginity. This is one of many reasons why [[spoiler: Sydney]] delays having sex with [[spoiler: Adrian]] until more than halfway through the book.
* ''Literature/SchooledInMagic'': Some spells must be performed by a virginal women, and so there's an entire group of them called the Virgin Sisterhood, protected by their armed, intimidating sisters.
* [[InvertedTrope Inverted]] in M. J. Scott's ''The Shattered Court''. In this world, women often receive magical powers on their 21st birthday, and are expected to be blessed at their nearest church once this happens. This "blessing", though, secretly drains most of a woman's power, transferring it to the church and later their husband. It only works on virgins, though, so the protagonist keeps her full magic, and ends being so powerful it freaks people out, since this is a world where a woman whose had sex before she's 21 is a complete anomaly.
* ''Literature/TheToughGuideToFantasyland'' has an entry for Virgins, and lists various reasons they're important, including unicorn (and, less commonly, dragon) bait, magic users ([[WitchClassic Witches]] possibly need to be virgins; Talented Girls are ''assumed'' to be virgins but don't seem to ''lose'' their Talent when they inevitably hook up with a male hero), sexual slavery, and of course, VirginSacrifice. It also adds that [[AManIsNotAVirgin nobody wants male virgins at all]], with even the sex-slavers preferring male slaves to have some experience.

[[folder: Live-Action TV]]
* In ''Series/{{Angel}}'':
** Cordelia discovers that her demonic powers can be transferred sexually (at least to one other person). In a subversion, this requires not that she maintain her chastity indefinitely, but just until she acquires a supernatural prophylactic. It's very much indicated that the reason supernatural prophylactics exist is precisely because there are plenty of powers in the Angelverse that come under this trope and therefore the means to circumvent this trope was, quite naturally, invented as a response.
** There are also demons who care about this, as became important when a man intended to sacrifice his virgin daughter to one. He hired Angel to guard her because he'd heard of his status as a ChasteHero. As it turned out, Angel was missing and Wesley impersonated him, and...yeah. The inevitable occurred. Although this didn't even matter -- he wasn't that good at isolating her previously.
* ''Series/BuffyTheVampireSlayer''
** One scene has Willow looking at some phlebotinum and saying "You know, a dash of this mixed with a virgin's saliva will...do something I know nothing about."
** There's also "[[Recap/BuffyTheVampireSlayerS1E4TeachersPet Teacher's Pet]]", which involves a Praying Mantis demon looking to mate with virgin males, in an interesting subversion of the trope. Of course, Xander, who has been professing his masculine sexual prowess for the entire episode, falls into the demon's trap, and consequently has to endure the barbs of his friends for being a virgin. It's made a little more tolerable for him by the discovery that the year group's stud who had been making Xander feel inadequate for his lack of sexual experience was also entrapped by the demon.... meaning he was a virgin, too. Xander may have been embarrassed, but the jock was downright humiliated.
* On ''Series/{{Supernatural}}'', during a hostage situation, it's revealed that the problem could be solved by a virgin sacrifice, and there Just Happens To Be a very religious virgin girl in the police station. However, (a) the Winchester boys decline to kill her (even though she volunteers upon finding out the stakes), (b) during the course of the battle, she decides she'll rid herself of that virginity as soon as they're out of it, and (c) [[spoiler: she ends up dying anyway]].
* Subverted with no small amount of glee on an episode of ''Series/TheDrewCareyShow'', where [[{{Satan}} the Devil]] -- or someone who definitely thinks he ''is'' the Devil -- insists he's going to get married to Kate and take her away with him. About to win a game of pool for double or nothing (her soul and Drew's), he boasts, "In the corner pocket... Devil's about to take a virgin bride!" At which point Drew and friends cackle. Upon finding out [[ReallyGetsAround she has had sex]], he insists "there's leeway," and whispers a question the audience doesn't hear. Looking almost embarrassed, she says, "Just once." He storms out, saying, "You people are sick!" and resulting in the immortal quote:
-->'''Lewis''': If you're lookin' for a virgin, stay out of Cleveland, buddy!
* Played depressingly straight in an episode of the short-lived 1997 series ''Series/ConanTheAdventurer.'' One of Conan's many doomed love interests starts out a virgin warrior who can magically adorn herself with impenetrable armor and gain incredible strength and speed. She and Conan eventually fall in love and have sex. She later dies after being captured, because she couldn't do the armor thing anymore. At least he got laid that time?
* ''Series/XenaWarriorPrincess'' the big thing is blood innocence, Gabrielle has not '''killed''' a man.
* {{Subverted|Trope}} in ''Series/DantesCove,'' where [[spoiler: a virgin is someone who has never used magic.]] Luckily for the characters, because [[EverybodyHasLotsOfSex a literal virgin would be even harder to find.]]
* When a vampire is delivered to the flat of ''Series/TheYoungOnes,'' Vyvyan argues that vampires only attack virgins. All four lads are quick to deny their eligibility, but the vampire itself remarks "what a choice!," confirming that they're all lying.
* In the ''Series/IClaudius'' miniseries, a Roman soldier hesitates to execute a condemned family's young daughter because she's a virgin, apparently fearing the gods may punish him for such an unprecedented act. He's ordered to [[RapeIsASpecialKindOfEvil subvert this trope in the worst way possible]] before he kills her.

[[folder: Music]]
* According to Brobdingnagian Bards, virgins have one of the least useful (but most plot driving) superpowers ever: tasting extra good to dragons. Discussed at length in [[https://www.youtube.com/watch?v=bdTJ4ZSkxJo Do Virgins Taste Better?]]

[[folder: Mythology]]
* In Myth/ClassicalMythology, three of the goddesses -- Athena / Minerva, Artemis / Diana, and Hestia / Vesta -- were "virgin goddesses." Whether "virgin" meant never having had sex, or merely meant never having been married, is a subject of some scholarly debate. In any case, their special status would have been nullified if any of them ceased being a virgin. In the case of at least one of these goddesses, her temple priests were also expected to be virgin women, and their authority as priestesses would likewise vanish should any of them cease being a virgin. These priestesses were, of course, the Vestal virgins.
* According to Roman tradition, Vestal Virgins were imbued with powerful magical powers as the health of the Roman State directly depended on their dedication. It was said that they had the power to freeze runaway slaves in their tracks if they have not yet left the city limits and their curses led to the grisly deaths of the first few Christians who tried to defile the Temple of Vesta. They also had many more mundane powers, such as being able to own property and draw up contracts, and any slaves and prisoners they touch must be immediately freed.
** The plot tension usually associated with this trope, however, was noticeably absent that one time Artemis thought to have found a worthy partner: The hunter Orion. Unfortunately, her [[MySisterIsOffLimits jealous brother]] put a gory end to the wedding plans...
* Medusa was originally a beautiful priestess of Athena. However when Athena caught Poseidon raping her, she transformed Medusa's beautiful hair into serpents and made her face so terrible to behold that the mere sight of it would turn onlookers to stone. That was the later, darker - and more well-known - version stated by Ovid in ''Literature/TheMetamorphoses''. The older version says that their affair was consensual. In fact, it's very hard to tell even what Ovid meant, as the ancient Greeks (and a number of modern cultures) define rape as having sex with a woman against the wishes of her patron - either her husband, her father, or in this case, Athena - the consent of the woman being inconsequential.
* As the goddess of chastity, the nymphs who followed Artemis also had to be virgins. Whenever one of them lost her virginity (usually thanks to Artemis' ''father''), Artemis would cast them out.
* In the ''Literature/{{Mabinogion}},'' the main work of Welsh mythology, the god Math ap Mythonwy would die unless his feet rested in the lap of a virgin while he was not at war. When his original virgin was raped while he was off fighting, Gwydion suggests his sister Arianrhod as her successor. To prove her virginity, Arianrhod had to jump over Math's magic wand. She immediately gave birth to two sons. Needless to say she was out of the running and royally pissed. There's a reason one of her roles is the goddess of revenge and karma.
* In Chinese folklore, Hé Qióng, aka Immortal Woman He or He Xiangu, the sole female among the Eight Immortals, took a vow of chastity while still human and fourteen years old, when a vision in a dream instructed her to eat powdered mica, in order that her body might become etherealized and immune to death. By doing so and remaining chaste, she was eventually able to live without any food, and eventually [[AscendToAHigherPlaneOfExistence achieved true immortality.]]
* In the ''Literature/{{Mahabharata}}'', a young princess by the name of Kunti receives a mantra that she can use to summon a god for sex. She is told that she can use it up to five times [[TechnicalVirgin without compromising her virginity]]. She does so, and has five sons as a result, the Pandavas. She gets curious, and uses it one more time than she's supposed to, and has another son by the name of Karna, whom she sends away.
** Her daughter-in-law Draupadi is also informed by [[UsefulNotes/{{Hinduism}} the god Shiva]] that her virginity is renewed each time she bathes. When the Kauravas start SlutShaming her for having five husbands and refusing to have sex with Duryodhana in front of his court, the Brahmins in the area refuse to do any work, because of her honor being dragged through the mud. [[PalsWithJesus She is also very close with Krishna]]. Draupadi and Kunti are both honored as holy virgins, both in the epic itself, and in the context of Hinduism.

[[folder: Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons''
** The Vow of Chastity Feat in the ''Book of Exalted Deeds'' suppliment gives a character many benefits for maintaining virginity. This Feat is a requirement for two prestige classes offered in the book (one of which involves acquiring a unicorn as your companion, naturally). The spell ''lantern light'' from the same book requires the character to abstain from sex for at least 24 hours before casting it.
** The 3rd Edition ''Oriental Adventures'' book had a PrestigeClass called the Eunuch Warlock. [[EunuchsAreEvil Being evil is a requirement.]]
** ''Magazine/{{Dungeon}}'' magazine #23, adventure "Deception Pass". The soothsayer Lyllidia is a FortuneTeller with a limited ability to see the future. She has taken a vow of chastity in order to avoid losing her powers.
* Zzaburi in ''TabletopGame/{{Runequest}}'', caste of magi of which one of the restrictions is chastity. (So much so that it is only the caste made up children originating in other castes.)
* Avalon Hill's ''Powers & Perils'' RPG, ''Heroes'' magazine Volume 2 #2 article "The Sea of Tears". Ghia Trell has a Creature Power related to unicorns and unicorns feel comfortable around her. If she ever has sex with a man she will lose these abilities.

[[folder: Theater]]
* In ''Theatre/{{Comus}}'', it protects the Lady from Comus.

[[folder: Video Games]]
* Mint from ''VideoGame/TalesOfPhantasia'' is a borderline case; although most of her powers are usable whether or not she's a virgin, she can't meet with the Unicorn who augments her abilities if she's not a virgin -- or even if a non-virgin girl is accompanying her, causing the flirtatious seventeen year-old Arche to leave during the portion of the quest where you seek it out. Then again, this is probably because unicorns have a long tradition in folklore of only appearing to virgins.
* In ''VideoGame/TalesOfPhantasia's'' distant prequel, ''VideoGame/TalesOfSymphonia'', the unicorn can again only be approached by "a pure maiden". ActionGirl HelloNurse Sheena gets quite [[{{Tsundere}} snappy]] when Raine implies [[PluckyGirl Colette]] will have to go alone.
-->'''Sheena''': Hey! Are you saying that I'm not qualified?!\\
'''[[ChasteHero Lloyd]]'''/'''[[BrattyHalfPint Genis]]''': Qualified?\\
'''Sheena''': Y-You don't have to both say it at once!\\
'''[[TheStoic Kratos]]''': ...Then we shall send Colette and Sheena.\\
'''Lloyd''': Why can't the Professor go?\\
'''[[TheSmartGuy Raine]]''': Because I'm an adult.
** Raine's comment that she is an adult was likely an excuse, it is more likely she refused to go because [[WhyDidItHaveToBeSnakes she is afraid of water.]]
* One of the sillier scenes in ''VideoGame/UltimaVII'' involves a unicorn NPC that doesn't really dislike non-virgins, but is capable of instantly telling the difference. Unless you've visited the in-game brothel before, your party members (one of which is a lecher, and another of which is married) are quite amused to learn that you are a virgin. Since the game had no way of telling whatever your protagonist has done ''in the previous nine games'', the unicorn [[HandWave simply reveals]] that you "regain your virginity" whenever entering the realm of Britannia.
* A Star of Destiny in ''VideoGame/SuikodenII'', a unicorn, can only be hired if you have a female virgin in the party when he's encountered. The StalkerWithACrush schoolgirl Nina usually qualifies for this; the list of characters that make the cut is oddly telling. Bring [[OlderThanTheyLook Sierra]] to him and he briefly approaches her... before freaking out a little and quickly making his apologies. She's vaguely insulted.
* Toyed with in ''VideoGame/TheWitcher''. At one point, you need to obtain the tears of a virgin for a potion that would cure lycantropy. The obvious solution is to ask the nuns at the local hospital, but virgins can also be found among the townsfolk--though, curiously, only women, except for a single man: [[spoiler:the upright and pious-to-a-fault knight Siegfried]]. Too bad the potion ultimately does not work.


[[folder: Web Comics ]]

* [[http://www.goats.com/archive/060314.html "The Knack" for interdimensional travel]] in ''WebComic/{{Goats}}''.
* Male example: Zander in ''Webcomic/{{Metanoia}}'' is [[DoubleEntendre Ridden]], or a voluntary conduit for an angel. Virginity is part of keeping one's "aura clear" to allow the angel to work through; other requirements include vegetarianism and not swearing oaths.
* A trade paperback-only strip for ''Webcomic/TheOrderOfTheStick'' has the party encounter a unicorn in the woods. Haley tries to approach the unicorn... only for it to roll over on its back, laughing.
** Also defied when [[MakesSenseInContext Lien the Paladin is captured by the tribe of orcs to be sacrificed to their new god... Banjo the Clown.]] She tells them they cannot sacrifice her because she is not a virgin before the orcs say that ''that'' was the point, since they wanted to sacrifice someone with experience (whether Banjo would have accepted the sacrifice at all is a different matter entirely.)
---> '''Lien:''' Why does my mother always end up being right about these things?!
* In the Superhero Arc of ''Webcomic/ArthurKingOfTimeAndSpace'', a bank robber called The Unicorn, whose costume includes a horn, is powerless to fight Batman-counterpart the White Night ... aka CelibateHero (at the time) Lancelot.
* ''Webcomic/{{Oglaf}}'' probably inevitably plays with this trope occasionally:
** Only virgins can see the Enchanted City of Vanorva. Because of this, the entire population of the city is celibate, to avoid accidentally depopulating the city. If a supposed slut somehow enters the city (even if the sex activities were not consensual, [[ButtMonkey as most of Ivan's were not]]), there is a widespread panic. Except, blowjobs don't count. Or [[ComicSutra flang]]. The jury's still out on anal. Ivan tried to convince Navaan it was okay, but she had second thoughts [[spoiler: after seeing the soldiers looking for them]].
** In the two-strip story "The Virgin Cobbler", the highly skilled title character tells her aristocratic clients that her skills are empowered by her virginity. [[spoiler:One comely female client sets out to ensure that none of her rivals will ever acquire more stylish footwear than her own by deflowering the cobbler. (Lesbian is assumed to count here.) The cobbler seems quite happy with that, and then goes off to buy a potion of virginity restoration. The punchline is that the cobbler knows that the potion is just sugar water, just like cobbling skill comes from talent and practice. She and the potion vendor share an opinion of rich people.]]
** In the three-strip story "Lapis Lazuli", Vanka attempts to steal two huge gemstones from a temple, only to be stopped by two monks who claim to be undefeatable in battle, due to an "ancient secret". Vanka spots the text on their idol which says "purity is strength". She promptly seduces them, rendering them unable to even punch her, let alone stop her from leaving with the gemstones. [[spoiler:They then change the inscription to claim their weakness is bees]].
* In ''Webcomic/SpareKeysForStrangeDoors'', [[http://sparekeyscomic.com/index.php?comic=20120809 one reason dismissed for ability to deal with the unicorn.]]
* In ''Webcomic/DarwinCarmichaelIsGoingToHell'', unicorns are attracted to virgins. In much the same way a horny adolescent would be. [[http://dcisgoingtohell.com/205-off-leash-unicorn-park-part-x/ "JUST TOUCH IT. TOUCH THE HORN."]]
* ''Webcomic/KarinDou4koma'': Mifi has [[InformedAbility some sort of power]] as the shaman of a now-vanished tribe that requires her to be a TechnicalVirgin. [[LoveableSexManiac Elza]] ''insists'' on respecting this, to Mifi's immense (sexual-)frustration.
* In ''Webcomic/SkinHorse'', the cast has to get through a system that will only let a princess through. [[WholesomeCrossdresser Tip]] is willing and ready to pass as a princess, but one of the tests to pass is a series of questions called the "Purity test". [[TheCasanova Which he very much fails]], as it needs a "total, inexperienced, never-been-kissed virgin". The one person in the team who fits that, much to his annoyance, is Nick, a former [[NerdsAreVirgins shut-in nerd]] turned BrainInAJar, who's currently possessing a female drone body.
* In [[http://www.teamfortress.com/bloodmoney/#f=6 this page]] of the VideoGame/TeamFortress2 [[AllThereInTheManual supplemental comic]] ''Blood Money'', we find out Merasmus is a virgin apparently for the convenience of getting virgin blood for whatever ritual you need it in a hurry. Of course, the 'young innocent female' side of this trope is subverted by the fact that Merasmus is a [[Really700YearsOld 6000-year-old]] male CardCarryingVillain...
* Yeon Yihwa's aunt and matriarch from ''Webcomic/TowerOfGod'', Yeon Hana, made a deal with a [[PhysicalGod Guardian]] that she shall not have sex or be in a relationship with a man after her first love went sour. In return she got quite a bit of power.
* Averted in ''Webcomic/KillSixBillionDemons,'' as of December 2015. Our heroine Allison is a virgin (the comic starts with her boyfriend being prevented from deflowering her), but her sexual inexperience has hardly been mentioned since -- staying alive on alternative planes of reality has been a much more pressing issue.
* ''Webcomic/SaturdayMorningBreakfastCereal'' makes fun of this trope in comic #[[http://smbc-comics.com/index.php?id=4026 4026.]]

* In one episode of ''WesternAnimation/{{Futurama}}'', the mutants below New New York require a virgin sacrifice. Leela volunteers, and they use her... mostly due to a lack of options.
-->'''Vyolet''': Nice try, Leela, but we've ''all'' seen [[CasanovaWannabe Zapp Brannigan's]] webpage.\\
'''Raoul''': When El Chupanibre comes for the, uh, "virgin", he will be snared by this rope trap.

* From the EvilOverlordListCellblockB:
-->If a malignant being demands a sacrificial victim have a particular quality, I will check to make sure said victim has this quality immediately before the sacrifice and not rely on earlier results. (Especially if the quality is virginity and the victim is the hero's girlfriend.)
* TheAdvertisingServer has made allegations concerning our very own JustForFun/TropeTan.
* One traditional way of locating a vampire's grave requires a young boy riding a male horse over every grave in the cemetery. When the horse refuses to walk over a grave, that's the one you're looking for. Both boy and stallion must be virgins. Unique in that it requires an animal virgin.
** More commonly, the horse must have never stumbled--which is probably less common than equine virginity.
* In ''Literature/ChaosFighters: Chemical Warriors-PERAK'', the brown sword operates at a lower power output when a person ejaculates and drops to minimum when said person had sex. So far, the brown sword wielders are all men.

* In North-Rhine Westphalia and other parts of Germany, there is a tradition that any man who is over 30 and unmarried has to sweep rubbish from the steps of the town hall until he is released by the kiss of a virgin. This has resulted in work colleagues and/or friends trooping to sufficiently public steps when someone turns 30 and making the 30-year-old cross dress and sweep straw/bottle caps until kissed. In one particular case, at first a girlfriend was sufficient. This escalated into three random passersby. In other cases, the guy gets released by a kiss from a pre-pubescent girl. This is really not as squicky as it might sound, though, as the kiss in question is a quick peck on the cheek (which is a pretty normal greeting in Germany and a very normal greeting in most other European countries) and at least in the cases of the pre-pubescent girls, they're often relatives of the guy or one of his friends.
* [[UsefulNotes/ElizabethI Elizabeth I]] decidedly stayed unmarried to remain in power. Being unmarried was to remain a virgin in her times, and she happily used all contemporary tropes concerning virtues of virgins and the Madonna mythos to further her status. (It wasn't truly known if she did remain chaste, but it wasn't like any of her subjects in those times was going to be rude enough to ''ask'' her.)
--> "Queen Elizabeth was known as the Virgin Queen. As a queen she was a great success" (infelicitous schoolboy essay)
* A popular meme from [[ImageBoards Futaba Channel]] has it that any man (some versions include women) who is still a virgin after age 30 will become a wizard (魔法使い). Conversely, "wizard" is sometimes used as a slang word for a virgin over 30. Some versions of the meme go on to claim that the individual's magical powers will be lost if and when his virginity is. Presumably, [[IncrediblyLamePun A Wizard Didn't]] [[AWizardDidIt Do It]]. And presumably, [[Literature/HarryPotter Severus Snape]] was a wizard in more ways than one. Referenced in ''LightNovel/BokuWaTomodachiGaSukunai''. When the main cast play a virtual-reality fantasy RPG, Kodaka chooses "wizard" as his class... and starts with no spells, a modern, geeky outfit, and a backpack full of anime posters.
* Gardasil vaccine against cervical/vulvar cancer is most effective if done before first sexual intercourse. This has nothing to do with virginity in itself, though, it's just that if you had intercourse you might already be infected. Being free of certain diseases could be a virgin power...
* Though it didn't technically gave her powers, UsefulNotes/JoanOfArc used her ChasteHero status as a proof of her purity and the fact she was serving God. (This is one of the reasons she was canonized as a Saint, not because, as commonly believed, she was a martyr, which she technically wasn't.)
* Some UsefulNotes/StraightEdge individuals take the subculture's anti-promiscuity ethos to this extreme.
* Some artists are celibate so they can channel that excess energy into their work. For example, French author [[Creator/HonoreDeBalzac Honoré de Balzac]] once claimed a friend's gift of a trip to a bordello cost him multiple novels.
* A [[https://twitter.com/RemingtonWild/status/939742121367445504 recent myth]] to pop up in the weirder parts of the internet is built around the idea that losing your virginity, if you happen to have your reproductive organs on the inside, has an effect that increases the length of the penis that is involved in the encounter. Of course, this is ''very much'' not how ''anything'' works, and makes absolutely no logical sense for bonus points, but since when has any of that mattered to strange people on the internet?
