Sometimes, plain old vanilla-flavored sex just won't cut it. For some, it takes ''actual'' cutting, biting and drinking of the resultant flowing blood to get sexually turned on. When one or more characters enjoys Hemo Eroticism they need to "feed" on others, and probably enjoy being "fed upon" by their partner in a similar fashion. Characters with this {{Fetish}} aren't necessarily violent, they may look for willing partners rather than kidnap someone and strap them down. Nor are these characters all [[HorrorHunger blood addicted]] [[OurVampiresAreDifferent vampires]], though this group does make up a majority of this trope's examples. What unites all Hemo Erotic characters is that they can only be sexually aroused or satisfied when blood is involved, sometimes accompanied with ritualized cutting or biting.

That said, this trope is strongly connected with the InterplayOfSexAndViolence involved in most sensual blood drinking, especially if vampires are involved. For them Hemo Eroticism is BetterThanSex and often forms a part of their feeding habits. Between two vampires (or a vampire and their preferred mortal lover) feeding on and being fed from are the ultimate, and perhaps only, means to express physical love. It's important to make the distinction that while it's possible for a vampire to make the character they feed on enjoy it by employing the KissOfTheVampire, the vampire may or may not enjoy Hemo Eroticism as well. Sure, the blood (probably) tastes good and it's easier to feed if the victim is having fun, but that doesn't mean they can only get off if it's involved. It may in fact be a sign that a vampire isn't [[FriendlyNeighborhoodVampires friendly]] when [[WhoWantsToLiveForever the ennui]] of [[ImmortalityImmorality decadent immortality]] has led them to pursue Hemo Erotic feeding to begin with.

Even mortal characters who are into Hemo Eroticism can sink into TheDarkSide of this fetish. What sometimes happens is they're such perverted [[TheHedonist hedonists]] that the pain is what they're ''[[TooKinkyToTorture going for.]]'' To that end they may use other wicked and sharp instruments like knives, razors, or FemmeFatalons to kink it up further. Especially deviant vampires may purposely abuse the fact that [[VampireBitesSuck vampire bites can be painful]] to get sadistic kicks while they [[FangsAreEvil sink their fangs]] into a victim. Oh, and if they're also a CombatSadomasochist? Best to run before they [[LickingTheBlade lick the blade]].

Neutral pronouns are used in this description because gender rarely matters to the Hemo Erotic characters. The character in question may also fall into one of the following: LesbianVampire, PsychoLesbian, DepravedHomosexual, and DepravedBisexual. Compare InLoveWithYourCarnage.

!Examples:

[[foldercontrol]]

[[folder: Anime and Manga]]
* Tsukuyomi from ''Manga/MahouSenseiNegima'' gets a little too excited from wounding her opponents (especially Setsuna).
* Part of the confusion from fans as to whether ''Manga/{{Vassalord}}'' is a BoysLove series or not stems from the fact that the blood-sucking scenes between the two main characters are so blatantly erotic that the blood drinking almost ceases to be a metaphor.
* ''Manga/{{Hellsing}}'' does this a fair bit in all 3 of its incarnations, the most obvious example being Integra slicing her own finger open and [[FanService Seras licking the blood from it]]. Alucard lapping up Integra's blood when she's shot in his chamber also counts.
* Fai enthusiastically drinking Kurogane's blood from ''Manga/TsubasaReservoirChronicle''. Works by CLAMP usually have this trope.
* Used in [[{{Narm}} a rather unintentionally hilarious]] way in ''Manga/HaouAiren''. At some point Kurumi donates blood to Hakuron to save his life, and when he wakes up and finds out, he bites open the skin on his wrist and starts licking up his own blood, because even though they can't be a couple in real life, at least they can be together inside his bloodstream. [[BigLippedAlligatorMoment W H A T.]]
** Also, some of the sex scenes in this particularly DarkerAndEdgier Creator/MayuShinjo manga have blood (not real one obviously) splashed across them.
[[/folder]]

[[folder: Comics]]
* [[AlphaCouple Henry Preston and Pearl Jones]] from ''ComicBook/AmericanVampire'' have a very kinky sex life where Pearl [[KissOfTheVampire feeds]] off of Henry [[TheImmodestOrgasm mid-coitus]].
[[/folder]]

[[folder: FanFiction]]
* A kinda common fanon among {{Hetalia}} fans has Romania as one of these. Often tied to the fanon belief that either he's a vampire or poses as one to {{troll}} people.
[[/folder]]

[[folder: Film]]
* The various vampire-club scenes in the ''Film/{{Blade}}'' franchise often involve the vampires being aroused while feeding. In fact, the series begins with a vampire-rave in which vamps are sprayed with blood, then start getting hot and heavy.
* In ''Film/BramStokersDracula'', when Dracula gives Mina some of his blood by slicing into his chest, boy howdy does she make it look sexy.
* In ''OnceBitten'', the main character thinks he is going to have a night of great sex with the attractive female vampire. When he wakes the next morning, she says he was "wonderful." letting him think he's had sex, when she was really drinking his blood.
* Used horrifyingly in ''{{Hostel}} Part II''. A girl is hung upside down and slashed across the back with a scythe, while the woman doing it lies beneath her, [[BloodBath bathing in her blood]], and clearly getting off on it, till she finally [[SlashedThroat slices the girl's throat]], killing her, and then [[CrossesTheLineTwice orgasms from it]].
* This is one of the themes of ''{{Thirst}}''. The main character is a priest before he becomes a vampire; his affliction massively enhances his senses and desires, causing him to feel lust for the first time. When he is alone with his girl, he wants to have sex with her ''and'' wants to drink her blood - and does both, at the same time. She wonders out loud if it is weird that [[TooKinkyToTorture she enjoys it.]]
* ''Film/{{Videodrome}}''. When Max learns that Nicki is a masochist, she asks if he wants to try out something. He pierces her ear with a needle, and licks off the blood.

[[folder: Literature]]
* Sheridan Le Fanu's ''{{Literature/Carmilla}}'' very much implies that the titular character derives erotic satisfaction from sucking blood.
* A rather vague passage in Creator/BramStoker's ''Literature/{{Dracula}}'' suggests that a new vampire can only be created if a bite victim somehow ingests vampire blood. Then again, the same book was criticized for its "sucking sounds" which many readers interpreted as suggestive of oral sex rather than blood drinking.
* In the ''AnitaBlake'' series, [[HornyDevils vampires of Belle Morte's line]] tend to do this, both between vampires and mutually between a vampire and a close human/[[OurWerewolvesAreDifferent therianthrope]] partner.
* In ''TheHollows'', the taking of blood by a vampire is very definitely akin to sex and is a turn-on for both the human and the vampire. Vampires will sometimes feed off each other as a pleasurable act.
* Invoked in ''TheSookieStackhouseMysteries'' as well as the TV series based on them, ''TrueBlood.'' A vampire's desire for blood is intrinsically tied to their sex drive; not only is biting/drinking de rigueur during sex, once during the books, [[spoiler:when Bill is almost completely starved for blood, he attacks Sookie both physically and sexually until he's sated enough to come to his senses.]]
** Being bitten/giving blood to a human is a massive turn on in both the books and the show, as well. At least in one instance, Eric literally gets off on having Sookie drink his blood.
* Works this way in TanyaHuff's ''Literature/BloodBooks'' and ''Literature/SmokeAndShadows''. Vampires ''definitely'' get off on feeding, especially violent feeding. Humans may or may not enjoy it too depending on their own nature and how the vampire goes about feeding from them.
* In the ''Literature/VampireAcademy'' series, drinking someone's blood is seen as the ultimate domination. Doing it during sex is just plain kinky and weird. One of the series' FantasticSlurs, "bloodwhore" revolves around that fact.
* Happens a lot in ''TheVampireChronicles'' by AnneRice. It's also shown as erotic between vampires and humans.
** It helps that vampires are no longer able to have sex (those organs simply won't function, no matter how much blood you pump into them), so all their pleasure comes from drinking blood. In one novel, Lestat temporarily becomes a human again. One of the things he ends up doing is having sex (with a nun, by the way).
* In ''Literature/{{Fledgling}}'' by OctaviaButler, feeding between Ina (vampires) and humans isn't necessarily erotic, but usually leads to erotic feelings between the human and the vampire.
* Inverted in ''Literature/TheDresdenFiles'', where [[spoiler:Susan]], a half-turned [[OurVampiresAreDifferent Red Court]] vampire, gets her [[HemoErotic hungers]] "confused" when it comes to her love interest. [[DeusSexMachina Their chosen method]] of artificially sating her [[HorrorHunger hunger for blood]] should be obvious. Played straight with some of the [[HornyDevils White Court]] vampires, and various other depraved and/or monstrous characters.
* In ''[[Literature/NightWatch New Watch]]'' by SergeyLukyanenko it is hypothesized that this accidentally created the first [[OurVampiresAreDifferent vampire]]. Some [[ChaoticEvil Dark Other]] was getting off from sucking people's blood. Once he left a drugged victim to die in [[DarkWorld Twilight]]. Instead the victim lived long enough to be transformed by Twilight and the drug[[note]] into a creature that lives off negative emotions siphoned through Twilight, can transform itself and cast spells, but needs blood to repair its body and quench hunger[[/note]].
** It's believed that werewolves started in a similar manner.
* Jack and Bobbi from ''TheVampireFiles'' put a ''lot'' of foreplay into their neck-nuzzling sessions, and Jack's more than willing to get her off in other ways after he's drunk as much of her blood as he dares for a given night.
[[/folder]]

[[folder:Live-Action TV]]
* Mitchell and Lauren in series 1 of ''Series/BeingHuman''. Mitchell says at one point that he "has trouble separating" sex and blood-drinking.
** The American version is the same. Yet Aiden has mostly avoided it because he does not drink blood except when he dated another vampire and even then he felt guilt about it.
* ''Series/BuffyTheVampireSlayer'':
** Some humans pay vampires to suck their blood for the thrill of it (as a metaphor for prostitution).
** Vampires also bite each other during sex.
** A Season 2 flashback of Angel being sired by Darla.
* One time on ''Series/ForeverKnight'' when Nick couldn't repress his urges any more he called on Janette, his vampire friend. It was implied that this wasn't an unusual occurrence amongst vamps in general.
* ''Series/TheXFiles'':
** Episode "3" in season 2 had the sexy vampire Kristen Kilar who licked her own blood and blood of other people, which was clearly sexual experience for her. She had some explicit scenes, including the one where she was shaving [[ShirtlessScene shirtless]] Mulder and offering him to taste her blood.
** {{Discussed}} in the episode "[[Recap/TheXFilesS05E12BadBlood Bad Blood]]" when Sheriff Hartwell asks whether there is some kind of disease that makes a person think they're a vampire. Agent Scully knows her stuff and answers that there is a psychological fixation called hematodipsia which causes the sufferer to gain erotic satisfaction from consuming human blood.
* Episode "Blood Lust" of ''Series/MurdochMysteries'' played with this, but since the setting is the late nineteenth century Toronto, it was toned down a bit. However, Detective Murdoch must deal with a vampire craze created by the recent publication of Creator/BramStoker's ''Literature/{{Dracula}}'' while he investigates the death of a young schoolgirl. Three other girls claim they have regular romantic encounters with a vampire and they all bear mysterious vampire-like bite marks on their necks.
* In ''BloodTies'', [[FriendlyNeighborhoodVampire Henry]] gets most of his blood by seducing girls (it's not difficult with his looks and charm, even without hypnosis) and biting them during sex. They just think he's being kinky. Given how Nikki's expression when Henry was feeding on her, the feeding is also pleasurable for the human. It's unclear what they thought about having two wounds on their necks in the morning.
* Some vampires in ''{{Moonlight}}'' keep humans around to suck blood. Both find the act pleasurable. And yes, vampires can have sex with humans and each other.
[[/folder]]

[[folder:Music]]
* Music/VelvetUnderground: The sado masochistic song "Venus in Furs" closes with Lou Reed droning: "Now bleeeeeeed for me!"
* Music/PJHarvey: The song "Happy and Bleeding" from the album "Dry" features the protagonist "happy and bleeding for you".
[[/folder]]

[[folder: Tabletop RPG]]
* In ''TabletopGame/VampireTheMasquerade'', human blood is to animal blood like a premium steak is to Spam. The same applies for vampire blood in relation to human blood, making for ''quite'' a bit of vampire-on-vampire action involving blood. Oh, it's also ''addictive.''
** Also vampires are ([[DependingOnTheWriter usually]]) incapable of enjoying sex very much without drinking their partner's blood during coitus.
* Drink another vampire's blood in ''[[VampireTheRequiem Vampire: The Requiem]]'' and you risk becoming addicted to it. It is easy to mistake this addiction for love, which vampires are incapable of truly feeling.
[[/folder]]

[[folder: Visual Novel]]
* In ''VideoGame/{{Hakuouki}}'', all but one of Chizuru's five potential love interests become [[OurVampiresAreDifferent furies]] and are thus plagued by cripplingly painful attacks of bloodlust, leaving her with the choice to feed them her blood or not. As everything is shown from Chizuru's perspective, the guys' feelings when they drink her blood aren't shown, but the scenes it occurs in range from vaguely sexualized in Heisuke's route to ''very'' sexualized in Hijikata's.
* ''AkaiIto'' is a perfectly non-18+ GirlsLove VisualNovel, but ''all'' the blood-sucking scenes are treated like this. There is even an Attempted Blood-Sucking that, for all purpose, is an AttemptedRape.
* ''AoiShiro'', its sort-of sequel, takes the same approach. And this time they even add TwinThreesomeFantasy to the HemoErotic.
[[/folder]]

[[folder: Web Comic]]
* Discussed in [[http://keychain.patternspider.net/archive/koc0068.html this strip]] of ''KeychainOfCreation''.
[[/folder]]

[[folder:Web Original]]
* In ''Roleplay/TheGamersAlliance'', quite a few of the succubi from the [[HornyDevils Eastern Horde]], such as [[EliteMook Lust]], are more than happy to bite the partner they're having sex with and suck their blood, thus mixing extreme pain and extreme pleasure together to create the ultimate sensation.
