Soldier: Is it true you went twelve-for-twelve with last year's Maxim cover models? Tony Stark: That is an excellent question. Yes and no — March and I had a scheduling conflict, but fortunately the Christmas cover was twins.
Does sex just happen as naturally as breathing around you? When alone with a woman/man, is the next shot always of the clothes hitting the floor? Did an instant harem or stable appear at your house? Perhaps you have a Compelling Voice, and take to its logical conclusion. You almost certainly make Bow Chicka Wow Wow music on the soundtrack when you walk down the street. People will look.
You, my friend, are The Pornomancer. In pornographic movies, the characters usually don't earn their sexual conquests so much as receive them from some greater power... whether that power is in-universe magic or simply a godlike, but lazy, writer or director (or both). There wouldn't be much of a porn movie if the characters didn't have sex, and nobody involved, including most of the audience, cares whether the seduction would be plausible in the real world. So it isn't. Thus, in the grand tradition of wizards who are helpful to lazy writers, this field of study is known as "pornomancy."
Often pornomancers are a walking Deus Sex Machina, but they can exist in more family-friendly works, such as The Casanova in a sit-com, or the Femme Fatale in a detective show. Pornomancy is often exhibited by Stupid Sexy Flanders and any other character so hot that they engender attraction from same-sex heterosexuals.
Pornomancy is sometimes blatantly supernatural in a work, particularly in Hentai, where powers are almost immediately used for their most sexual application upon being obtained or there's actually a loose magical justification for all that sexing, but more often the cause of a character's ability to make respected citizens become slobbering sex maniacs is completely non-magical within the context of the show's universe: it simply starts off as an Informed Ability and everyone pretty much accepts it as a given (with the occasional Hand Wave when writers feel frisky). Even if the show has no established super-normal content, pornomancy is still possible through TV magic.
The Pornomancer is a non-gendered trope often combined with The Casanova, Even the Guys Want Him, Even the Girls Want Her, The Vamp, Femme Fatale, Stupid Sexy Flanders, and other tropes that take note of the tendency of characters in fiction to have nigh supernatural powers of getting laid. Kavorka Man would be a sub-trope; by definition his power over women is mysterious and ill-defined. In worlds where magic or its sci-fi equivalent exist, this is often related to Power Perversion Potential.
Aversions of this trope occur when, for example, The Casanova "earns" the conquest plausibly to the viewers. Subversions take place when the Informed Ability turns out to be just that... for example, the Femme Fatale's charms fail and she strikes out miserably; it's also a subversion when the person with said powers knows he or she can use them for sex, but doesn't.
It's also possible for a person to have this ability but not want to use it. If the Pornomancer is apathetic or even against his/her own abilities, they are an Accidental Pornomancer.
More scholarly tropers should note that the prefix of "pornomancer" is being used in its more modern sense of an abbreviation of "pornography" rather than carrying the direct meaning of the root word "porn?" meaning "prostitute".
When used as a defined in-universe power, this is a subtrope of Whatevermancy, but doesn't have to be. When it's just implied because the writers want a character to have improbable fornication skills, it is not.

Anime & Manga
Basically the entire concept of DNA² with the Mega-Playboy having a Marvel-style mutant power (i.e. it naturally activates at puberty) to become such a perfect man that he can literally seduce any female (except his Victorious Childhood Friend who's immune to his charms since she's known him for so long) into falling head-over-heels in love with him with just by looking at them. That, and he also gains instant Saiyan-level combat prowess.
In Ai Yori Aoshi, the male lead is in a committed (if secret) relationship with the first girl, but for some reason he attracts girls with a tendency to fall in love with him, appear half-dressed, and/or grope one another.
Taken to an extreme in Chapter 273 of Hayate the Combat Butler'. Hayate being a Chaste Hero, he doesn't even realize he's doing it, though it is noticed by the other characters and one tries to follow his example to his love interest. It doesn't work.
Revolutionary Girl Utena: Akio exhibits this trope. Touga as well, although he's not quite as skilled as Akio (and to be fair, Akio's pornomancy seems legitimately magical, whereas Touga is just suave.) eventually Touga decides to submit to Akio's power and become his herald / implied buttboy. Touga's best friend calls him out on it, and Touga admits that being around that much power feels just plain good.
My Balls has the demon sealed within Kouta's bollocks actually doing this to him. Most of it is justified in that the demons of hell are trying to make him ejaculate, so that the demon sealed in his balls will be freed. However, there's also a normal instance of this trope in Minayo, who has the worst timing EVER in revealing that not only is she interested in the boy, but that she also becomes a raging nymphomaniac when drunk.
Irresponsible Captain Tylor has Tylor himself. After saving the ship as he always does by just being his blissfully ignorant and incompetent self, the other crew members give him a porno tape and wanted him to enjoy it for himself, but threatened him if they didn't get it back. Blissfully unaware that there is an alien princess hiding behind his bed (who honestly doesn't know anything about human relationships), Tylor puts in the tape, but keeps fumbling to turn it off as EVERY FEMALE ON THE SHIP comes to his door to express their sexual desires for him. Hilarity Ensues. On top of that, Tylor ended up joining the military to begin with because his ignorance ended up causing a female COMPUTER to confess her love for him in the first episode!
Yurika's Campus Life is about a girl with the rather strange gift of female-only Pornomancy, to the point that even men recognize her as beautiful, yet somehow not attractive. After a few chapters worth of denial and accidental sexing, she comes to terms with this and amusingly becomes known as "the girl with the stamen", using her skills at female love to score food and a place to stay.
Lester Girls from The Trouble With Girls is an inversion of this. Everywhere he goes there will invariably be hoards of women lusting after him, much to his displeasure. One of his big desires is to meet a nice normal girl who doesn't try to get into his pants five seconds after saying "Hi!"
And while we're on the subject of Archie — how does that plain, ordinary guy with no money, poor grades, and little talent except an occasionally demonstrated musical ability get two girls to fight over him all the time? Not to mention get a date with anyone who happens to be just passing through Riverdale?
Iron Man: Tony Stark is very much this. A quote from the movie (when being asked if he went "Twelve for Twelve" with the Maxim covergirls) explains it all: "Yes and No. March and I had scheduling conflicts, but December was twins."
Matsuda: (wearing an ugly suit) Hey, Light-kun. Light: What is it? Matsuda: Uhh, you're good with girls, right? Light: (thinking) Hell yeah, I have! (out loud) Well, I have had quite a few girlfriends over the years. So, I guess you could say that. Matsuda: Well, you see... I'm going on a date with someone in an hour, and, uh, I was sort of wondering if you could give me some advice... Light: (thinking) Well, that explains the ugly suit. (out loud) Oh, sure. Do you want to learn how to make her like you, or how to make her want to knock you over and fuck you into a mattress? Because I'm fairly good at both.
Films — Live-Action
As seen on the page image, Tony Stark a.k.a. Iron Man, right from the start of the movie. While establishing his character, it's shown that he can easily turn a reporter from trying to paint him up as some kind of evil warlord to falling into bed with him in about 20 seconds.
In Perfume the sociopathic protagonist with an inhuman sense of smell makes a perfume Powered by a Forsaken Child or seven that, when applied, causes everyone in a large area to not only love you, but also tear off their clothes and have sex with everyone around. He uses it at a public event with hundreds of people. This scene also occurs in the novel.
Dangerous Liasons and remakes like Cruel Intentions specifically avert this trope by spending quite a lot of time on the planning and implementation of a seduction.
James Bond's talent with pornomancy is legendary; nearly every movie he is featured in has him seducing women under the most peculiar circumstances and using the most improbable techniques. The most recent, rebooted Bond movies have played with it:
Much of Casino Royale was built around a fairly massive subversion/aversion of this: Vesper Lynd is set up as a typical Bond conquest-to-be, but instead of that he falls for her, hard, and she completely plays him. Given how Casino Royale is Bond's origin story, it's more accurate to say his callous womanizing stems from their destructive relationship. Few people realize his signature vodka martini is actually symbolic: Bond names it after Vesper and then continues drinking it long after she's dead.
This trope is so prevailing that it's a bit of a stunning subversion when one realizes that, in Quantum of Solace, he doesn't sleep with Olga Kurylenko's character, Camille. Not to worry though. During the course of the movie, Bond manages to bed Gemma Arterton's character, Agent Fields, who was sent to retrieve Bond from his mission. All it evidently took was the come-on of "finding the stationary" in their swank hotel room. His callous treatment of Agent Fields is perhaps the biggest indicator in the movie that the Bond of this movie had no use for personal entanglements, focused as he was on revenge.
Ironically, the only woman that Bond may have truly loved, the one who he actually married (in On Her Majesty's Secret Service), was murdered by Ernst Stavro Blofeld less than an hour after the wedding. It may well be then, that it is somewhat justified that he will not commit to a woman a second time.
All of the British Sex Comedies of the 1970s. But especially the Timmy Lea Confessions of series, Adventures of series, and The Ups and Downs of a Door-to-Door Salesman (a film which screamed for sequels).
Easier to count women in Witcher series that didn't tapped Geralt than those who did. Slighty justified because the witcher's wierdness acts like a magnet... or because Geralt seems to be some kind of alter ego for Sapkowski. Though it only true in the short stories. During the entire penthalogy (roughly five years), Geralt slept with the grant total of three different women.
What discussion of sex magic would be complete without Anita Blake? Though the series began merely using sex as appropriate to a modern vampire story, as it progressed, it got further derailed to the point where nobody can resist having sex with Anita, and she can do anything she wants with sex magic.
Laurell Hamilton's other major character, Meredith Gentry, also qualifies: she's been able to bring creatures of Faerie into power via sex, and even revive parts of the Unseelie enclave.
Sir Apropos of Nothing gets a ring (that does not go on his finger) that gives him pornomancy in The Woad to Wuin, the second book of the series. Subverted in that it quickly proves to be a curse: "The women came to me in all shapes, all sizes, young and old, pretty and... less so. Finally they tied me to the bed. There are worse ways to pass one's hours, but none come readily to mind."
This is the power of one of the families of the White Court of Vampires, which they use to facilitate their feeding on a person's soul and life through sex. If a vampire gets hungry, gender-appropriate preys will try to get close and tear their clothes off. The vampires can tone the effect to tolerable levels, though. It should be noted that gender DOESN'T matter for the White Court. If it has a libido, they can eat it.
While Harry himself is an aversion, wizards are known to have this effect. It actually serves as a decent early-warning sign of dark wizards, aka "warlocks". Magic is heavily tied to the wizard's sense of right and wrong and the fact that magic that takes control of people means that the person doesn't consider what they're doing abusive is a pretty good clue that someone is up to no good. Harry's strength — and certain Mantles of Power that he has — make a lot of the major magical players want him on their side. Many of them are Femme Fatales or have them on staff for that purpose.
The Sidhe are capable of doing this almost without thinking.
Mikael Blomkvist, the male lead from Stieg Larsson's Millennium series. There are only two female characters featuring in more than a few paragraphs that Blomkvist doesn't sleep with. One is a married woman with young children and the other is his sister. It never seems to be Blomkvist who seduces them either, it just seems like every female jumps him as soon as she gets a chance. Luckily the movies downplay this. Some of this is due to Larsson's editors making him put more sex scenes in because they felt it would give the novels more commercial appeal. By the third book they stopped doing this and it shows.
The Marla Mason series by T.A. Pratt actually uses the word "pornomancer" to describe Tantric magicians who derive power from sexual desire and sex-related emotion. There is also a character described as a "lovetalker" with the magical/psychic ability to involuntarily evoke feelings of attraction and affection in everyone around him, making him irresistible.
In Smoke and Ashes, Leah is this by virtue of being the handmaiden of a demonlord of lust. It fizzles when she attempts to use it on gay men however.
Dune presents Duncan Idaho as a lampshaded example. His charm with the women is remarked upon by more than a few characters throughout the entire original Frank Herbert run of the series. Not bad considering that he gets killed partway into the first book. And near the end of the third. And countless times in the fourth. Being able to bed almost every female character in the universe is most likely just karmic balance for Duncan being the Duneiverse's resident Cosmic Plaything.
Joey from Friends is possibly the most famous modern pornomancer. Despite not having any magical skills (or intelligence) of note, he rarely needs to utter more than "Hey. How you doin'?" before scoring.
Ironically, his skills beyond that single line are nearly non-existent. When the phrase does fail him, he goes into a Heroic BSOD.
Chuck Bass from Gossip Girl. Nate Archibald as well, but to a lesser degree.
Dean Winchester alternates between being a pornomancer and actually being a viable romantic lead. The third season premiere started with Dean cavorting with "the Doublemint Twins" in a hotel room while Sam hides in the car. Though the show does contain magic, it's reasonably certain that he didn't need anything more than Author Appeal to cross that one off the bucket list. In several episodes, however, such as with Cassie in the episode "Route 666", the tenderness is definitely earned.
Subverted by Andy Gallagher in "Simon Said": he has the power to control people with his Compelling Voice; he refuses to use it to seduce the woman he loves.
iCarly: Spencer. Basically scores with every woman on the show older than 18, and younger than Mrs. Benson. Also scored with Mrs. Benson in the Christmas Episode. And a 80 year old guy whilst Spencer was pretending to be a busty old woman. In episode Locker 239 he may have had a girl in his room at the start of the episode, and then scored with the art teacher at the end of that episode.
Surely Charlie from Two and a Half Men is an 18th level Pornomancer? Admittedly he's probably Charlie Sheen's own Marty Stu, but the guy's been laid more than the contents of 12 egg cartons.
In Night Court, prosecutor Dan Fielding's whole life revolved around his sexual conquests. Humorous given that the actor later went on to play a character on Boston Legal, which had its own fair share of pornomancers.
Barney from How I Met Your Mother is a master of this, not only does he have an arsenal of magic tricks, he once managed to pick up a French chick whilst pretending to be an 80-year-old man. Marshall, apparently, is not so sure. Barney is seen successfully scoring with increasingly bizarre tactics, but by his own admission he has actually flirted with way, way more women than he has slept with. Basically, his pornomancy is a servant to Rule of Funny, and if it's funny for him to get martinis thrown in his face that will happen instead. One episode has Marshall using GMB's photocopying department to make an absurd number of graphs: Barney's success rate is, apparently, only about 1%.
The episode 'Stuff' highlights some of the weak points in Barney's game; although he is shown on-screen with a great success rate in picking girls up, it apparently falls apart fairly often on the way back to his or her place. Barney's solution? Turn a moving truck into a one-room bachelor pad in the alley behind the bar. Though, according to his own admission, he has never had a "perfect week", (7 women in 7 days) though he has tried to. Somewhat Truth in Television, Barney is using what might be called "The Shotgun Approach". Basically, he tries so much, so often, that the law of averages kicks in. Even if he only scores once for every 50 shots he takes, he shoots so much that that still means he'd get more tail in a week than most of us would see in a lifetime.
Coupling: Patrick keeps a closet full of video tapes of women he has slept with. One made a sex toy from "Junior Patrick". He doesn't understand the idea of friendship with a woman. In any particular room in which women are present, it's expected to find that many have been "patricked".
Chris Stevens of Northern Exposure has this power. There's an episode devoted to it, in fact.
Lt. Matthew "Can't Keep It In His Pants" Scott bagged at least two women in the first four episodes, neither with any pretext whatsoever. A flashback during those episodes mentions that as a teenager, he'd gotten his girlfriend pregnant. After that ignominious start, he settled down for the next two seasons with just Chloe.
The real Pornomancer is Lisa Park, who's not only slept with as many people, she's done so in less screentime (two in one episode, one in a webisode). More to the point, while Scott's liaisons are at the very least an attempt at an actual relationship, Park is doing this just to relieve stress.
Author Hank Moody, played by Real Life pornomancer/sex addict David Duchovny, is Cursed with Awesome pornomancy. An endless slew of gorgeous women fall into his bed; even his daughter and his soul mate usually just roll their eyes when they find out about his sexual shenanigans. A case could be made that his power is Blessed with Suck (heh), since his life is always complicated by his sexual antics. One generally doesn't feel sorry for him, however.
By Season 3, about the only adult women on the show he hasn't slept with are Marci, his best friend's wife, the boss of his best friend, and his daughter's best friend. He has slept with Mia (the 16 year old daughter of the man he took his wife back from), his teacher's assistant, a stripper/student in his writing class, the wife of the dean of the school he's working at, Karen, and about a half-dozen random sexual encounters. It finally comes crashing down in the Season 3 final episode.
** In season 5, it appears that Charlie is now the show's resident pornomancer. As of episode 7 he's shown having sex with four women and gotten a free blow-job from a transgender hooker. Meanwhile Hank, in the same amount of time, has had sex with a grand total of two women. One of which he was in an actual relationship with.
Season Two: Cordelia dumps Xander, so he tries to win her back with a love spell. It works, but not on its intended target (obviously). Hilarity Ensues. It might be better to just declare Xander the series Pornomancer, period. At one point or another, every human and non-human chick alive (plus one undead) in the series has wanted to fuck Xander's brains out. By the third, season, he already banged the character played by Eliza Dushku, and by the fourth season, he was regularly engaging in sex marathons with his nympho ex-demoness girlfriend (who was the patron saint of scorned women and as such, THE absolute man-hater for 1100 years until she met Xander).
Season Seven: there's a boy at the rebuilt high school whom all the female characters immediately fall for, with dreamy expressions and the theme from A Summer Place. Even Willow (she started working a spell to change him into a woman so it could work for her). Hilarity Ensues. It's the jacket.
LOST: James "Sawyer" Ford gets laid more often than any other character on the show, on or off the island. Likewise, any women that Jack shows interest in, such as Ana-Lucia, Kate and Juliet, seem to always end up sleeping with Sawyer first.
Douglas Renholm on The IT Crowd fancies himself a Pornomancer but the jury's still out on whether or not he actually is one. He failed to seduce Jen, but things like iPod parties seem to back up his claims.
One episode of The Golden Girls had Dorothy dating a short, nerdy, bald man whom she and the other ladies found inexplicably irresistable and kept throwing themselves at him. The man had apparently dealt with this his whole life.
Don Draper from Mad Men gets picked up by ridiculously beautiful women and he hardly has to raise an eyebrow at them.
Captain Jack Harkness of Doctor Who (and Torchwood) thrives on this trope. One time, he was sentenced to death and somehow talked both of his executioners into bed ("lovely couple, they kept in touch"). Another time, the man whose girlfriend he was forced to shoot in a Mercy Killing and who vowed to watch him die a painful death ended up his "naked hide-and-seek" buddy (and, later, boyfriend) instead. He spent about a week in occupied London in WWII, posing as an officer with a stolen name, and managed to bed at least two soldiers during that time. When he eventually met the guy he stole the name from, they ended up making out in the middle of a crowded ballroom. And so on, and so forth.
Sam Malone from Cheers was an odd case. While he was indeed well known for being a seducer who had slept with numerous women, he spent much of the plot of the show trying hard to seduce women who wouldn't submit so easily. Diane was the first tough case (who eventually did succumb, whom he actually felt true love for, and tried to marry... It didn't end well) and later Rebecca (who he did sleep with after a long and unsuccessful campaign to seduce her, but only because she wanted a child).
Tone Loc will tell you that, while the Funky Cold Medina always works on the ladies, you should always be careful of what you wish for.
Even now, when he's in his 70s, Tom Jones can sing women out of their clothing at will.
Unknown Armies has a whole school of magic called Pornomancy, based on the rites of the Naked Goddess, a porn star who ascended to the Invisible Clergy by fulfilling the archetype of the Woman Everyone Can Have But You. Pornomancers accumulate charges for their magic through ritual sex, recreating the roles the Naked Goddess played in her films, and can use these charges to do pretty much anything on this page. Beware though, this is Unknown Armies and every school of magic restricts its practitioners; if a Pornomancer has sex for love, enjoyment, or any purpose other than ritual, all of their magic is negated.
The horror RPG Kult features the Lore of Passion, which allows for magical seduction among other sex and fertility effects. Also, Body Horror. There is ALWAYS body horror in Kult.
Most White Wolf games feature a power or ability that can be used for this purpose.
Exalted features a charm called Husband-Seducing Demon Dance, which works on everyone that can see you. Being that it works on a person or cause, it can be used both for instant seduction, instantly recruiting a Redshirt Army or becoming a one man Propaganda Machine. Being Exalted, it's available to a starting character.
On a related note, Alchemical Exalted can get the Thousandfold Courtesan Calculations. which lets them have sex that is so good it can be used as a form of mind control. Of course, the sex has to be consensual for the mind-control effect to work, but it's doubtful that anyone with the charm is going to have that problem.
There's even a whole Sidereal Martial Arts Style (that being the most powerful level, which is about as similar to mortal martial arts as theoretical physics is to arithmetic) — Sapphire Veils of Passion — for this sort of thing. One particularly fun technique makes anyone who grapples you lust after you.
Vampire, both of them, are naturally the most prominent example in White Wolf's library. With two entire magical skills dedicated to making the Vampire irresistible in some fashion, and with several abilities of other disciplines able to do the same. Dominate allows you direct orders, and Majesty/Presence allows you to become unnaturally sexy to everyone around you, and they can't explain why.
From Requiem, there's the Daeva Bloodline, the Duchagne, whose primary power is Licencieux, which can cause spontaneous waves of pain or pleasure in the target, meaning you can make anything attractive or repulsive, not just yourself. Bonus: repeated uses on the same target following a repeated action can cause addiction. Addiction to the caster's favor, addiction to doing as they're told, addiction tocontributing to wikis... the applications are endless.
This is the nickname for a certain Archetype in Shadowrun, who can throw a ridiculous amount of dice at any social roll. Their powers aren't explicitly related to sex, though the ones capable of spellcasting often end up taking the spell that induces a mass orgasm for the take of living up to the name. And yes, that is a canon spell. Presumably, it's quite popular at certain parties.
This is an inherent power of all werewolves in Werewolf: The Apocalypse, although it won't work on anyone who's already in love or in a committed relationship. There's actually a good reason for them having it BEYOND Power Perversion Potential. Breeding is VERY important for the Garou, since being a Werewolf is in the blood...only they can't breed with other Garou, without cranking out a deformed child called a Metis (which you can play as). Since Wolves spend a LOT of time fighting the Wyrm and dealing with their own brand of tribal politics, its a little...difficult to get into a committed relationship (but not impossible), making one night stands preferable. That's right, Pornomancy is almost mandatory for their very existence.
The demon lord Graz'zt from the Dungeons & Dragons setting is an extreme example. His reputation as a rake and a seducer is legendary; there are numerous myths and stories about his affairs with mortals, female demon lords, and even goddesses. Most of his servants are female demons, and not all of his conquests were consentual ones. This behavior has caused him to sire numerous children, most of which are vile villains in their own right. The most infamous one is Iuz the Old, a tyrant who rules an empire on the world of Oerth.
In Jason Robert Brown's The Last Five Years, Jamie finds that after he is married, women begin throwing themselves at him. Due to his crumbling relationship with Kathy, he eventually caves into temptation.
Ric Flair aka "The Nature Boy", so named for his old nemesis Buddy Rogers (himself named after an obscure country song). He went through many permutations in his character before settling on a Hugh Hefner-type ladies' man, known for his limos and flowing Liberace robes.
A more contemporary version would be the late Nelson Frazier aka Viscera, among whose many gimmicks was an oversexed hybrid of Mr. T and Barry White.
Wrestlecrap: RIP Nelson Frazier. In related news, Trojan and Durex have filed for bankruptcy.
The Witcher: Geralt of Rivia can't seem to avoid falling into bed with townsmaidens, nurses, and sorceresses; some of the sillier things that lead to sex for him include passing a quiz on the language of the Elves and giving a ring (any ring) to a young woman who is jealous of her sister's marriage... it can be any ring. Luckily for him, STD Immunity and sterility are standard effects of Witcher mutations. And a literal example exists in an off hand note that magic can induce orgasms.
The so-called "Romantic Encounters" mod for Baldur's Gate II adds many dialogues that can make the PC into this. It also modifies an existing mage in the sewers (Mekrath) into a more or less literal Pornomancer.
Commander Shepard is memetically infamous for this due to the wide range of romanceable companions. Averted within the context of a single character's playthrough, though, as Shepard can't be in more than one relationship per game and changing your romantic interest in the sequel is likely to result in a scene when both paramours confront each other over Shepard. However, if a single game is compared to a Bond movie... And there are optional one-night-stands with the Consort and Kelly Chambers. Shepard definitely CAN be James Bond IN SPACE if he or she so desires. It is possible for a male Shepard to bed six separate people over the course of the trilogy if he wants (Liara or Ashley and the Consort in 1, Jack, Kelly, and Miranda or Tali in 2, and Steve Cortez in 3).
The Illusive Man is apparently well-traveled as well, according to the dirt the Shadow Broker has on him.
There's a PG version with Zelos Wilder in Tales of Symphonia. The man is so pretty and so charming that women of all ages give him money and gifts just for talking to them. Literally. It's a gameplay mechanic. In a rare introspective moment he suggests women love him only because he's The Chosen One, but the free-gifts-from-women shtick still works in the parallel world where no-one knows who he is, so... yeah, Pornomancer.
Least I Could Do. Rayne is exceedingly lecherous, and supposedly has many conquests. Much like Barney Stinson of How I Met Your Mother, he uses the "Shotgun approach", according to one "Tao of Rayne" strip — "The foolish man concerns himself with the 99 who say no, while the wise man comforts himself with the one who says 'yes'." Character development and the writer's own growing up have severely downplayed this aspect of the character over the years, however.
Skin Horse: Wholesome Crossdresser Tip somehow manages to charm every woman he meets without even trying. The other characters jokingly refer to it as his "superpower". When Tip ends up getting turned into a werewolf, it turns out his "superpower" transcends species (and in once case orientation).
Zii of Ménage à 3 has probably had sex with most of the cast by now, one-shot characters included. She can seduce presumably straight girls (and middle-aged, married women) with ease, and once had a foursome with male triplets. Probably the only reason we haven't seen her use her Pornomancy on any gay men yet is because she'd rather watch them do their own thing (although in one what-if scenario created by Gisèle on Slipshine is an indication, she could easily do that too).
The Chupacabre in Girly is something of a light-hearted deconstruction of this trope. Any woman who sees him will immediately rip off her clothes and throw herself at him, and he is more than happy to give them the best sex they've ever had. And while sometimes this really does improve their lives, it's more likely to ruin any current or potential relationships they had. Chupacabre is completely unaware of this until Winter explains it to him, and makes a very concentrated effort to be more careful from then on. He's successful — mostly.
Sailor Sun: Crystal, the pink-haired girl, never speaks and communicates by mime or writing notes - not because she can't speak, but because she is apparently a Siren, and any male who hears her voice is instantly compelled to do whatever she tells them to.
Pibgorn: Drusilla can seduce pretty much any male character, whether man, boy or demon with ease... but, of course, she's a succubus, so that's pretty much a given.
Discovery: Prowl was apparently a huge slut back in the day; the comic has shown him use his animal magnetism to his advantage twice already.
Incubus Tales: Dhiar and Chana are Incubus and Succubus respectively, and both have tremendous ability for seduction.
Whateley Universe: Sara. As a demon princess of lust, she can actually hypnotise people into sleeping with her. She prefers not to, viewing it (somewhat accurately) as rape, although no-one ever complains, per se. It's a lust aura. After all, she is a granddaughter of Shub-Niggurath. And she's building up a pretty powerful harem: most of her conquests so far are mutants.
Tales of the Folly has a literal instance of unintentional Pornomancy: "Why do I feel frisky all of a sudden?" To a lesser (that is, withstandable) extent, all Chakat mating is this due to their empathy.
The erotica writer Salamando has a several stories involving Lust Walkers, succubus like entities that feed on "sex energy" to survive, lest they go feral. Each Lust Walker is named after a type of mythical creature (medusa, siren, vampire), which is based on both their method of feeding and the specific powers they gain. Another series of his features a world where all women on Earth above the age of 19 (but no men of any age) gain Sex Magic, enabling them to psychically sense men's arousal and read their naughty thoughts, and magically play with and control their bodies. They can also do this to other women, but only if the other woman allows it to happen.
The aptly named Ambrosia, a supervillain in the Global Guardians PBEM Universe is continually surrounded by a cloud of pheromones that make so attracted to her that they will do nearly anything to please her... including handing over an entire store's worth of jewelry, or the entire contents of a cash drawer, or shoot someone... and it works on both men and women. She has, on numerous occasions taken advantage of her one super-power to go into a single's bar and walk away with the prettiest people in the joint for a night of fun.
