Pick a Harem anime protagonist. Any Harem anime protagonist.
Death Note: Light Yagami is, in his own words, "pretty popular with the ladies". He isn't very interested in romance himself, but several times uses his natural appeal to his advantage, and at a few points is quickly and easily able to pick up a girlfriend as part of a plan (not counting Misa Amane's obsession with him).
Ranma Saotome of Ranma ½ is a little more competent but no less hapless when it comes to girls. Or guys, for that matter. And let's not get into the whole panda doodle incident. By the end of the series, a massive Love Dodecahedron is formed with him at the centre.
Negi Springfield from Mahou Sensei Negima!. He's a little too young to be worrying about love. Unfortunately for him, he's also a little too cute for his own good, which draws in girls that don't have any romantic interest in him yet. (A prime example is a chart, apparently made by Chamo, measuring the type and extent of several girls' affection for Negi is partially shown. One girl, while having rather low romantic feelings for him, has a maternal score of 12 out of a possible 10.) Having selective maturity helps. The situation is most likely going to get worse once he hits puberty, which has prompted Chisame to wonder if it's not best that they kill him now (chapter 125).
To make matters even worse, he has a habit of unintentionally saying things that sound like love confessions or even proposals. With a straight face (by which we mean an adorably innocent smile). Worse yet, he'll really and truly mean it, though not in the way the person he says it to will first interpret it.
Lampshaded in chapter 285 by Chisame again with an exasperated "We've got us another one..." after Shiori shows visible signs of attraction to Negi.
If you thought Negi was dense, you clearly haven't seen Kotaro. Natsumi, Mei and Madoka plus nearly as many nameless fangirls as Negi, yet manages to be even more oblivious than Negi. At least Negi understood the confessions he's gotten and picked up on.
Son Gohan from Dragon Ball Z briefly shows himself to be quite a hit with the ladies when he enters High School.
Fubuki from Yu-Gi-Oh! GX; he's fully aware of his powers, but is too carefree to consider exploiting it. He happily humors the female students who admire him... Most of the time. (In one episode he faces of stampede - literally - of girls chasing after him, and he escapes using a quick disguise.)
Kei Takishima of Special A, and probably every male member of Special A.
The entire Ouran High School Host Club, but especially Tamaki Suoh, whose good looks, suave manners, and genuine desire to make every girl he meets feel special and happy all make him the club's most popular host, and Haruhi, who is identified by the rest of the club as the "natural type" when she starts attracting fangirls just by being her normal self. Tamaki even gets jealous of her Chick Magnet abilities when she accidentally steals away one of his fangirls, and he rants that it's not fair that she's so good at getting girls when she herself is a girl.
Akito Tenkawa of Martian Successor Nadesico manages to attract the eyes of about half the female crew over the course of the series, to the vocal annoyance (and sometimes envy) of some of the male crewmembers. It gets Lampshadedconstantly.
Takuya Enoki from Aka-chan to Boku(Baby and Me) is this to a lot of girls. When he finds out that several girls are in love with him he almost has a mental breakdown. It appears to run in the family; his widower father Harumi has several coworkers who crush on him, and two little girls at the daycare fight over Takuya's little brother Minoru.
Jotaro Kujo from Part 3 was beloved by all the girls at his high school, probably due to his Troubled, but Cute image. They still think he's irresistible when he tells them to go away.
This also happens with the other JoJos of the different arcs, including a bit in Part 4 where this happens to another character who was disguised as the hero.
Jotaro, Josuke and Giorno all have a crowd of girls begging for their attention near their introductions; Jotaro and Giorno are too cool to dopily embrace it unlike Harem protagonists.
Hakuoh, from Duel Masters, was one of these during the first season, but he was too busy being aloof and dealing with the Serious Business of card games to care. After his Heel-Face Turn, the effect seems to wear off.
Rental Magica's Itsuki Iba who has at least three girls displaying affection for him, plus a younger one who looks up to him as her "onii-chan", and an older lady sort of likes him. And this doesn't stop on living or humans — one of the three girls is a ghost. Nekoyashiki began to muse aloud when a homunculus joined the ranks of female admirers.
Sasuke Uchiha from Naruto has so many emotional problems that he hardly even notices the girls that become entranced by him. You could probably count the number of girls his age (and younger... and a bit older...) who don't show attraction to him on a single hand. Considering he gets most of this when he's twelve, it gets a bit ridiculous at times. Things do even out later though.
Naruto doesn't do too bad for himself, either. Especially not if you consider the Filler arcs. And the movies. (Thinking of a particular post-credits gag in particular...)
In The Prince of Tennis, several popular players have their own fanclubs; some of those are Echizen (though Tomoka and Sakuno are the only fangirls seen often), Oishi (in the anime, and much to his discomfort), Keigo Atobe and Hiroshi Wakato from Jyousei Shonan (who also *adores* the attention from the ladies).
In one of the fanbooks, Fuji is said to be popular with the girls of his class. Not to mention his young admirer Kurumi Ijuin from the anime.
Yuta from Mermaid Saga, though played in a much more serious and tragic tone than any of the above, as Yuta knows any relationship he gets into will end badly for him. One time, the girl that fell in love with him was killed by her jealous fiance.
Interestingly enough, despite the fan club and 108 dates, both of Lelouch's main love interests start out thinking Lelouch is an arrogant Jerkass, and only fall for him after seeing his hidden kind side.
Keitaro from Love Hina fits in. By the end of the manga, only two girls had not fallen in love with him. One of them was eight years old...
Jing from King of Bandit Jing is definitely a Chick Magnet. 99% of the time, when his adventure has something to do with a girl, she'll fall for him. There's also a reason why they call all the girls in the series "Jing Girls".
Sagara Sousuke from Full Metal Panic!. Kaname, Tessa, and the novel-only character Nami are all in love with him, Ena Saeki has a crush on him, Mira Kudan apparently also fell for him and "gave her heart to him" ever since he saved her life, and there are strong hints that Grace Weissman (AKA Gray) had some feelings for him (or, at the very least was attracted to him). Indeed, his pheromones are so strong that he managed to get her to feel this way towards him in the span of a few days, despite him being really quiet and hardly talking. Oh, and he also has one crazymalestalker...
It's implied that a bunch of girls (and guys) at school harbor crushes on him and find him incredibly good looking... the thing is that his insane, violent behavior and unapproachability keeps them from daring to chase and pursue him.
Suguru Misato of Mahoromatic has all the girls in the series after him, including two (maybe all three) members of triomatic, Mahoro, and his slutty, depraved, insane teacher miss Shikijo.
Train from Black Cat is. He has three women vying for his attention (okay, well, one of them was cut short), but only manages to see them as friends / acquaintances because he's a Chaste Hero. Although he could be considered an even more extreme example in that Even the Guys Want Him.
Mizuiro is notorious for being a chick magnet. He's a small, with Raven Hair, Ivory Skin and an angelic face. He regularly nets himself older women who will also mother him, such as providing him with home-cooked meals. He's also mastered the art of the Clueless Chick Magnet. He knows precisely what he's doing but, because girls think he has no idea how attractive he is, it makes him even more desirable to them.
In the zanpakutou anime filler, Hyourinmaru is a chick magnet to the female zanpakutou. Tobiume, Haineko and Suzumebachi are all enamoured by him. Tobiume and Haineko even fight over him.
Allen Walker from D.Gray-Man doesn't do too badly for himself. Rohfa is infatuated with him, Road claims to love him, and one interpretation is that For may have a crush on him. In the second Reverse novel, it is also implied that Lenalee has someone she secretly likes, and that that person is probably Allen. And that's not even getting into the aspect of how Even the Guys Want Him, where Allen is shown to be able to manipulate Komurin (a robot) by turning up his charm (complete with Bishie Sparkle) which makes Komurin fall for him, or how Tyki really really likes Allen.
Akio Asakura from Wangan Midnight. In fact, when he ends up repeating his last year of high school due to excessive absences caused by driving the Devil Z at night so much, the lower-grade female students got excited over being able to attend high school with Akio for another year. Said obsession with the Devil Z prevents him from hooking up with them.
Nozumu Itoshiki of Sayonara, Zetsubou-Sensei, the certifiably suicidally depressed teacher whose fashion sense is stuck in the 19th century and whose personal goal is self-annihilation, somehow manages to get almost every girl in his class to fall in love with him by accident (or at the least make him the subject of their various fetishes and insanities, which is just as good... right?)
He manages to charm almost every female who encounters him, really. Even several who meet him with their only initial assumption being, "Evil, inherently heartless killing machine." Even the ones who don't fall for him want to adopt him; his elderly landlady treats him like a surrogate son, and at least one teenage girl decided she wanted him to be her big brother. About the only exception is Season 2's Mina Hazuki... a Psycho Lesbian who Does Not Like Men.
Kitano looks like this. The girls who very like him are a kind, but violent Action Girl, a stoic, but aggressive Dark Action Girl, a stalking Camera Fiend, and a half-American-half-Japanese first-year middle-school girl.
Paptimus Scirocco of Zeta Gundam fame. It's implied he uses Psychic Powers to subtley manipulate women. A particularily dangerous example, he has managed to weaponize this ability, convincing his lovers to fight & die for the sake of his nebulous goals & it's even implied his ultimate goal may be to use this power on a global scale.
Tsukune Aono from Rosario + Vampire. Any female monster who comes within smelling distance of him will want him for her own. This might be because his human blood is highly attractive to any monster, so the women just interpret it as sex appeal. Although his Nice Guy attitude and bishonen appearance are clearly contributing factors. In some chapters it's been shown that human girls find him attractive as well (possibly even his cousin).
Guts from Berserk. Not at all obvious in the Golden Age, which has as a plot point his slowly building relationship with Casca. Rather, it happens to him afterwards, where he seems to have more of a knack for having girls several generations his junior fall for him. Farnese (who is a generation younger than him) falls in love with and practically worships the ground he walks on. And then there's Schierke, who is more than a generation younger than him, and has a huge crush on him. It's implied that Jill (who looks to be around the same age as Schierke), an abused village girl, developed a huge crush on him as well (to the point where she repeatedly kept begging for him to allow her to permanently follow and come with him). And along with (much) younger girls, he also seems to be a demon magnet, and not just because of the Brand of Sacrifice he bears. There's Slan, the only female member of the Godhand, who is very attracted to him in an evil and sadistic way. Rosine, a fairy-like Apostle, flirts with and mentions how attractive he is (despite her almost Single-Target Sexuality obsession with Jill). And getting into Even the Guys Want Him, Griffith, who would become the latest member of the Godhand, had a Yandere obsession with him.
By the end of Girls Bravo the male lead Yukinari has about four girls after him, or who expressed interest in him at one time or another.
Yuuji from Shakugan no Shana. No only does he have two main Love Interests, he was also involved in...ehh...questionable actions with a female villain, is desired by another female Crimson Denizen for being the vessel of her lover, and becomes actually part of a Love Square due to a third girl clinging to him later on. And he still stays Oblivious to Love for a total of 2 Seasons.
Pokémon's Ash Ketchum. Many girls (human andPokémon) have developed feelings for Ash and he's too clueless to notice any of them.
Fuyuki Hinata of Keroro Gunso has attracted a lot of female attention for a twelve-year-old boy. Girls who have a thing for him include schizo billionaire heiress Momoka, School Newspaper Newshound Chiruyo, a mermaid, a princess on the moon (just go with it) and Alicia Southerncross, an Emotionless Girl with a shape-shifting space entity who happens to be her adopted father on her head.
Touya and Yukito of Cardcaptor Sakura both have large female followings at their school. Unfortunately for the ladies, they're also the series' official Yaoi Guys.
Lancer from Fate/Zero has this as a literal superpower, per his legend - any woman (without sufficient magical resistance, that is) who looks at his face is charmed to fall in love with him. The latest woman to fall for him had enough magical resistance. Even without his superpower, he's really charming.
Ayumu Narumi from Spiral attracts the attention of Hiyono and Rio thanks to his amazing cooking skills. After he meets Hizumi he goes on to find himself being confessed to nearly every day by girls who had been attracted to him but intimidated by his demeanor and the fact that he hung out with Hiyono all the time.
Agito from Air Gear attracts female nurses and doctors without even trying. He winds up in an early chapter, surrounded by a crowd of them.
Tadase from Shugo Chara!. He has half the female population of his school after him, and he is in 6th grade.
Compared to some of the protagonists of harem anime, Van of GUN×SWORD is only modestly successful, since he's only got three women chasing after him most of the time. However, he has the ability to attract women instantly. In episode 10, he receives a proposal of marriage from a successful businesswoman who wanted his assistance as an armor rider; in episode 21, he memorably gets a come on in the middle of battle from an enemy who finds him "adorable."
Ryuuji from Toradora!, despite having the Face of a Thug, manages to get all three main female characters in the series to fall in love with him. Even background girls start showing interest when the discover he's very clean, cooks, and sews quite well.
Black Butler: Sebastian — in the anime, at least. Sebastian has been shown to be attractive to Ciel's aunt, three nuns (one of which he has sex with for information one screen no less), and an angel.
In Katekyo Hitman Reborn!, way back at the beginning of the series, there's all those fangirls in the school dying to give Gokudera and Yamamoto chocolates.
And in chapter 364 when Dino introduces himself as Tsuna's English teacher quite a few of the girls and one guy blush over how dreamy he is.
Ali/Alan of the Sailor Moon anime suddenly gets a lot of fangirls when he transferred to Usagi/Serena's school.
Pandora Hearts: Gil in the anime, who was almost attacked by a hoard of frothing horny schoolgirls while in Lutwidge Academy.
To a lesser extent in the manga, too. Retrace 49 has a horde of noble females swarming around him and Vincent. We already knew Vincent was this as well, but this time we see them well-dressed at a noble party. All the girls are happy, inside and outside the universe.
Karakuridouji Ultimo: Murayama. He is so bishonen that school girls run and push desks over to see him and release heart marks while fawning over him.
Vampire Knight: Kaname. He already has Yuki, Ruka, Sara, and countless screaming Day Class girls who want him. Plus all those Nobles practically shoving their daughters at him at the Aido family's soiree.
Princess Mononoke's Ashitaka manages to effortlessly draw the affection of Irontown's entire female population. Even the married ones.
Speed Racer: Speed. Which naturally causes the occasional fit of jealousy on the part of his girlfriend.
Rin Tsuchimi of SHUFFLE!. By the end of Essence+ there is no girl shown on screen and has a name that isn't in love with him.
Tomoe and Kurama in Kamisama Kiss. The girls in Nanami's class almost start a war over who gets to sit near them.
Keima from The World God Only Knows puts a bit of a unique twist on it. First, he's actually highly unpopular. Second, he wants girls to leave him alone. Third, he's an InvokedChick Magnet because if he doesn't do it his head will be cut off. Therefore, he has to use tricks from romance games in order to quickly win over girls to free them from spirits possessing them. They are, in short, loving only what he wants them to see though rarely outright lying in the process. That said, it's hinted that a handful of girls would like him anyway since even if he's a nerd, he still has a reputation for mental strength and nonconformity.
Kamo, the male lead in Nejimaki Kagyu attracts a lot of female admirers the moment they look upon him. A problem he has to contend with when some of the female body of the school he teaches at use some rather violent means to gain his attention or try to take out any competition.
Both Yako and Mei from Yurara. Mei enjoys the attention and gladly flirts with any girl who talks to him, while Yako's fanclub prefer to admire him from afar, as he is decidedly less sociable.
Issei Hyodo in High School Dx D has amassed a harem, and quite a lot of girls (and even some guys) do want him. This is especially after he builds some muscle in which his entire class all have a crush on him despite knowing he's one of the three biggest perverts in his class. Humans, devils, an angel, and even a gorilla spirit are attracted to him.
Archie Andrews from the Archie Comics, for some reason. Thoroughly deconstructed when Betty brings over some photos of Archie. Veronica points out he's actually kind of ugly. This leads into them realizing he's selfish, boorish, and is generally bad, and they should both dump him. Beat. "You first." "No, you first." They glumly conclude that Archie is some sort of Kavorka Man.
And speaking of Archie Comics, Sonic the Hedgehog has attracted several potential love interests such as Princess Sally, Amy Rose, and Mina Mongoose.
Ryan Choi, The All-New Atom, finds himself utterly baffled by the way the women of Ivy Town find him attractive — including at least one supervillainess. He has to be reassured by Wonder Woman herself that there's nothing supernatural about it.
Daredevil... the Murdock mojo runs strong enough to leave even Spider-Man envious.
Longshot of the X-Men. This may well be a function of his (literal) supernatural luck, but there are other explanations.
Cyclops has had at least six different girlfriends, and that's just counting his mainstream version. Psylocke also once tried it on with him. In particular, he seems to be irresistible to telepaths. His younger self has only been in the future for a few months, and has still managed to catch the eye of at least five girls, then again he does display Cyke's Adorkable 100% of the time so it's really not a surprise.
Nightcrawler, sweet merciful crap. The guy has a list of girlfriends as long as his tail and all while he's short, blue, and fuzzy. Then again chicks dig the fuzzy.
Chicks dig the fuzzy indeed, as Beast can also count for this trope. During his tenure with the Avengers, it was not rare to see groups of women all over him whenever he went out, more than one expressing interest in running her fingers through his fur.
In one story, Supergirl spontaneously made out with him. She hastily apologized to Starfire, only for her to say she understood.
The apple didn't far fall from the adoptive tree, as Bruce Wayne has never had a problem with the ladies. Well, technically he has, but it's more of a "getting them to go away" problem than a "getting them to come by in the first place" problem.
His animated version even hooked up with Lois Lane. Even the Joker had to express his admiration for that one.
Former Robin and current Red Robin, Tim Drake, is no slouch either. While he's only ever been in a committed relationship with Stephanie (Batgirl), Darla Aquista (the Warlock's Daughter), Hong Kong gangster possibly undercover cop Lynx, Cassandra Sandsmark aka Wondergirl (though they ultimately decided they were Better as Friends), and possibly Cassandra Cain (she wasn't really herself at the time, being drugged up and crazy) have all been attracted to Tim at one time or another. Even Lady Shiva was a bit too touchy-feely with him when they first met than was really necessary.
Spider-Man as well. His lovers' gallery is probably exceeded only by Batman, and in Batman's case most of the relationships are merely used to maintain his playboy image. In fact, the Human Torch "snaps" when he learns that his best bud Spider-Man is actually Peter Parker, who he was extremely envious of for his ability to attract women. Johnny even labeled Peter's ability the "Parker Luck", much to Spidey's amusement, who uses the same term to describe his bad luck. If you still needs proof, take a look at the 'Love Interest' section of this page. He even nabbed Hercules' former wife!
Clark Kent/Superman. He's attracted: Lana Lang, Lori Lemaris (a mermaid!), Lois Lane, Cat Grant, Wonder Woman, Maxima, Amazing Grace, The Queen Of Fables, La Encantadora, Supergirl!, Ice (Guy Gardner's main squeeze), Obsession (Dana Dearden), a Latina cop, an alien insect queen that had taken Lana's form, and Lyla (a purple-haired chick from Kandor).
Conner Kent has attracted Supergirl, Knockout, Tana Moon, Roxy Leech, Wonder Girl (Cassandra Sandsmark) and Batgirl (Cassandra Cain). Chris Kent was dating Thara Ak-Var, and girls chased him wherever he went. Like father, like sons.
In the New 52, Superboy has Ship Tease moments with Caitlin Fairchild, Rose Wilson, and Cassandra Sandsmark. At one point, a random woman dumps her boyfriend and tries to chat him up.
The Hulk, surprisingly enough. A lot of women, both human and non human, seem to fall for him. To date he has been married at least three times (two now dead and one partially insane) and bedded many more. Bruce Banner on the other hand...
One of the main running gags for Ivar Anni-Padda in Valiant's Timewalker series. Whether he's walking down the street minding his own business, running for his life from the villain of the month or falling from the top of a skyscraper, all anybody can say about it is "Gorgeous!"
Doug Ramsey/Cypher of the New Mutants. He dated pre-bodyswapPsylocke as well as teammate Wolfsbane, but has also managed to earn himself quite the following of female villains.
The title character of the Den finds that he is this: a strapping, hung and nude hunk whom every female character throws herself at him.
Kyon, the titular character in Kyon Big Damn Hero. Being a brilliant martial artist as well as breaking up an illegal voyeuristic photography ring probably has something to do with it.
Koizumi too. All he has to do is walk into Kyon's class, and all the girls just stop what they're doing and stare.
Paul attracts his share of women (and men), but for one or another reason he never actually wants or gets any.
After Ringo defeats Mung, he is mobbed by the Warrior Women and has so much sex that the next day he's “little better than a smear on the ground.”
In The Tainted Grimoire, Luso has three girls who definitely likes him. They are Kanin, Anna and Maria.
Earth and Sky: Pipsqueak, who is described as "sma-hoking hot", and is eye candy for every mare in his age group. This is especially frustrating for Apple Bloom, before and after they hook up.
Despite his cold, cynical personality, Takeru from the Tamers Forever Series is still rather attractive to the ladies.
Spike in the Ponies Of Olympus series. In addition to Rarity finally realizing she returns his feelings, Wavedancer and Scales both develop crushes on him, and it's implied Scootaloo has a small one on him as well.
Emeth in Warriors of the World, to the point that both teenagers and women gasp and whisper when he passes by. He is markedly uncomfortable with the younger generation fawning over him, but uses his good looks and ladies' man skills to get information.
Kitsune no Ken: Fist of the Fox: Uchiha Sasuke is the most popular boy at Konoha High School, drooled over and idolized by most of the girls...not like he cares.
In Dauntless, Lelouch is this even more so than he was in canon. Once he is outed as a prince, he is quickly voted as "Most Eligible Bachelor" and has crazed fangirls trying to sneak into his residence. Gets downplayed after his arranged marriage. Jeremiah Gottwald is a lesser example when he attends a party at Ashford Academy in his and Suzaku's honor. He is very disturbed by the teenage girls' attraction to him.
Disney's Peter Pan has Tinker Bell, Wendy, Tiger Lily and a gang of mermaids all over him and easily jealous.
Films — Live-Action
Pootie Tang: For the viewers, he's a Kavorka Man, but none of the women in the film can (or want to) resist him. He rejects their affections until being tricked into losing his magical belt.
The title character in Austin Powers: International Man of Mystery. He also has allied female agents falling for him in the other movies.
In Captain America: The First Avenger, Howard Stark is the straightforward ladies' man, as shown in his first appearance. Post-procedure Steve was able to catch the attention of Peggy, the foxy secretary and a starstruck blond due to a combination of his stage celebrity, Greek God physique, courage and AdorkableNice Guy attitude.
James Hunt in biopic Rush2013, who allegedly slept with over 5,000 women in his lifetime.
Nawat Crow in Tamora Pierce's Song of the Lioness. His innocence is compounded by the fact that...well, he's a transformed crow and, in the beginning, misinterpreted kissing as mate-feeding and thought that a reasonable way to substantially increase the number of available warriors was to continuously mate and have nestlings. The fact that he's adorable doesn't hurt either.
In Simon Hawke's The Reluctant Sorcerer trilogy, women far and wide find the main character endearing to no end, because his nature strikes them smack-dab in their maternal instinct.
FitzChivalry Farseer by the time of Fool's Errand has become one. He's more a Deconstruction, however, because far from being too innocent or even-handed to take advantage of it, he's too emotionally crippled to sustain any kind of romantic relationship, not to mention being too hung up on his lost love from the first trilogy. When he tries, he ends up sabotaging the relationship pretty severely.
Holger Carlsen, the displaced-to-a-magical-world hero of Poul Anderson's Three Hearts and Three Lions, is bemused to find himself the object of eager affection from Morgan le Fay, an Elven enchantress, and a wholesome Swan May. Apparently he never had this much success with women in our world, which the narrator attributes to his having too much concern about hurting their feelings. This is at least partly due to a pair of enchantments placed on him at birth by The Fair Folk: to have the "gift of pleasing" and the "sensibility to return the affection he inspires."
Sir Berit and Sir Bevier, from David Eddings' Tamuli trilogy. Subverted in Bevier's case: he's well aware of his attraction to women but his religious scruples (he's aiming to convert from knight to priest at some point) mean he refuses to act on it. Berit is utterly naive, still completely loyal to the ideal of his vows and completely unaware of the effect he has.
Benjamin Avery, hero of The Pyrates. Every single woman in the book pursues him, from the pirate queen to the jungle princess, but he only has eyes for the admiral's daughter. For her he's not prepared to move beyond kissing until they're married.
Paladin of Souls presents Arhys dy Lutiz, who is blessed by the Father of Winter (god of leadership, justice, fatherhood, what engenders fatherhood, and so forth) to an almost embarrassing degree. The chain of events leading to his "condition" started when the sorceress sent to seduce his unmarried bastard half brother got a good look at him.
Isaac Asimov's Azazel series have a story about a man who was made that by the titular demon (he redesigned his body chemistry to produce a lot of pheromones). Unfortunately, all the girls are extremely jealous... and he ends up with the strongest one (that is, all muscle and brothers to match - 7 to 8 feet tall).
Mikael Blomkvist in Stieg Larsson's "Millennium Trilogy". The amount of women falling over themselves to sleep with this financial journalist is incredible, and one can't help but feel there is a certain amount of wish-fulfillment going on on the author's part. In The Girl With the Dragon Tattoo he is already having a long-term affair with his business partner Erika. Upon moving out to Hedeby island he is quickly seduced by Cecilia Vanger, whom he has an ongoing relationship with throughout the book. Then Lisbeth comes to town as his research partner and ends up falling in love with the guy. In the sequel, The Girl Who Played With Fire, Blomkvist is sleeping with Harriet, the woman he had believed to be dead for 90% of the first book.
Cedric "Pretty Boy" Diggory, to the annoyance of the other boys (especially Harry when Cedric asks Cho out first).
Thomas Raith of The Dresden Files, supernaturally so. He tries to hold down a job like a normal person... and keeps losing his job when women throw themselves at him. He eventually solves it, in a rather hilarious but effective way. Harry Dresden himself subverts this trope. He has a surprising amount of offers over the course of his adventures, but most of them are from evil, usually supernatural women (or magical beings taking the form of women) who would use the opportunity to murder him or weaken him. Harry knows this, and it is why he's essentially sworn off having relationships. Human women may be attracted to him in that way, but there aren't enough vanilla humans in the series to make that assumption.
Laharl in the Disgaea Novels. It seems he was able to attract multiple girls, including, Etna, Flonne, Jade, and Sakura
Georgina and Dorothea in Sorcery and Cecelia. The former is just that good-looking. The latter has a spell cast on her to make her irresistible to all men (and she hates it).
Jerin Whistler of A Brother's Price is a young man approaching the age of marriage in a world where such creatures are rare and treasured and guarded so as to protect them from "husband raids". When he goes out with his sisters to protect him he gets a lot of stares. In this world well-to-do women will see very few men; maybe their father and grandfather, if they're lucky their brother or husband, if they're very lucky their son, so any man with both eyes and all his teeth would be seen as exotic and attractive, but it's later confirmed that Jerin really is good looking even with other males to compare him to. A lot of people go after him over the course of the book, and it's a decided cause of stress and anguish, especially when he's kidnapped.
In Smallville, Clark Kent is this to ridiculous levels (and not without reason, judging from the squeeingfangirls). From main characters like Chloe, Lana, Lois and Tess, to minor characters like Zatanna, Maxima, Alicia, Kyla, not a single girl has not drooled over him, in most cases repeatedly.
It's a series-long Running Gag that he's a chick magnet for demons, attracting them at a supernatural (hah) rate. By the end, every single girl he's ever been interested in or been interested in him is some sort of demon or using demon powers (though retroactively in Cordelia's case).
Captain Jack Harkness is the poster boy for Extreme Omnisexual, which is good for him considering men and women of numerous species want a piece of him.
Auggie Anderson from Covert Affairs. It's played with a couple of times. One typical example:
Auggie is boarding a plane to Istanbul to attend a jazz festival and talking to Annie on the phone.
Annie: ...How, exactly, does a blind man navigate a huge music festival in a foreign city? Auggie: I know Istanbul better than some Turks, and for anything I don't know, I can always make a friend.
They're interrupted by a stewardess on the plane, who goes from slightly annoyed to blatantly hitting on Auggie within about ten seconds. Auggie doesn't seem to mind! After he gets back to the phone conversation;
Annie: ...Made a friend already, huh.
Stefan from The Vampire Diaries never has a shortage of girls looking his way. Neither does his brother Damon, but Stefan gets noticeably more attention than him from the females because he's much nicer than him.
Even though House is a miserable bastard nearing his fifties, nearly every woman on the show looks at him like they want to take him into a supply closet and jump his bones. His eyes can't be that pretty, can they?
On Cheers, Carla's ex-husband Eddie Tortelli has the odd ability to attract women to him, even though he rude and isn't all-too good looking. (In fact, at the end of one episode where Diane tells him off by claiming he has no such powers, he proves her wrong by simply breathing into her ear and making her swoon.) He can't seem to hold onto them, however. Not only did Carla divorce him for being a two-timer and a deadbeat father, but his second wife Loretta did too (but she came back to him later). Carla later tells her son's fiancé that this is common of Tortelli men, but she still marries him.
Spencer Shay, with Sasha, Miss Ackerman, Mrs. Benson (in an alternate universe), an art teacher, Gibby's mom, a female juggler, an 80 year old man, the woman who inherited Galini's pie shop, and more.
Freddie, with Valerie, Shannon, Rona (alternate universe), Melanie, Shelby Marx, Magic Malika, Jamie, Ariana, Leslie, Sabrina, Patrice, three random girls at a party ("iPity the Nevel") and the female fandom in "iStart a Fanwar", without mentioning that he dated both female leads of the show.
Don Draper, in Mad Men, can't go anywhere without being hit on by some girl or another. Unlike most examples, though, Don is perfectly willing to sleep with them, despite being married.
Will from Glee, having his wife Terri and guidance counselor Emma. Add to that, Rachel, Suzy Pepper, Shelby, April, and Holly.
Also, Puck. He's portrayed as a womanizer since day one, and when he opens a pool business he finds himself sleeping with various single moms she works for. And he has no shortage of girls his age either: there's Quinn (mother of his baby), Rachel (with who he hooked up twice, the second time while she's with Finn), Santana (dated and had sex multiple times before she comes out), Brittany (both admitted having sex with each other before the series begin), Mercedes (they date during an episode of season 1, and there's also quite a bit of Ship Tease later on), Lauren (his girlfriend in season 2), Kitty (who he dates during most of season 4) and Shelby (his baby's adoptive mom, with who he has sex with on season 3).
Benton Fraser of Due South, to the continual frustration of everyone around him.
Though usually a Handsome Lech who did this intentionally, Face on The A-Team could attract a woman even when he was focusing on something else. For instance, there was the time he had to hide from Col. Decker in a woman's changing stall:
Woman (to Face): I like your face. Face: Uh, you mean...I have an honest face? Woman: No, but I like it. *leans in towards him* Face: *goes with it and gets laid offscreen in a changing stall*
Wally Cleaver was never too concerned about girls, but the girls all seemed to consider him the hottest catch in school.
Davy Jones in The Monkees. One episode has the guys playing Spin The Bottle, with the bottle's mouth homing in on him every time. When he goes into another room, the bottle flies off the table and sticks to the door...
John Crichton of Farscape so so much. In addition to his main love interest Aeryn, there was Gilina, Chiana, Jenavian, Jool... any female character to show up in the show instantly falls for Crichton or at least gets ship-teased with him pretty intensely.
Beck from Victorious though he's totally commited to long-time girlfriend Jade.
Person of Interest: Lampshaded by a snarking Finch in "No Good Deed" when Reese fails to charm a receptionist into letting him in a building:
"I'm surprised, Mr. Reese, that nice young lady seemed somehow impervious to your charm."
Daniel Jackson of Stargate SG-1 had a new woman attracted to him nearly every single time they went to a new planet, including from several different species, and had more love interests than any other SG-1 member (all of whom died); hell, he was even raped by a Goa'uld once. It is very telling that when a Kull Warrior (actually Vala in disguise) calls him attractive, he doesn't doubt it at all.
Fonzie from Happy Days. Played with big time in the famous outtake where a prank was played by having all the *guys* crowd around him when he snapped his fingers instead of the girls.
Duncan MacLeod in Highlander...his frequent bedding of female guest stars was lampshaded in the parody song on one of the commercial outtake tapes. "He'll chop a head and land in bed with this week's guest star..."
The subject of the Carl Perkins song "Everybody's Trying To Be My Baby", quite fittingly covered by George Harrison of The Beatles.
Went out last night, half-past four, fifteen women knockin' on my door...
Went out last night, I didn't stay late, 'fore I got home I had nineteen dates...
Adonis of Greek Mythology. So handsome that two goddesses fell in love with him at first sight. Aphrodite took a shine to him when he was born and Persephone fell for him when he was about thirteen. It didn't end well for Adonis — when he eventually chose Aphrodite, a furious Persephone told Aphrodite's former lover Ares about Aphrodite's new beau. Ares turned into a boar and attacked Adonis while he was out hunting. Since Ares is a jerk, he killed Adonis by goring him in the crotch.
Diarmid O'Dyna of Celtic Mythology (who was Lancer in the aforementioned Fate/Zero) had this as an actual magical ability — any woman who looked at his face would instantly fall in love with him. One of these was a woman who caught sight of him at her own wedding party. Her husband-to-be didn't take it very well.
In Popeye, Because of his silver tongue, Wimpy certainly didn't have a hard time wooing the ladies, and would definitely try if he heard they had access to hamburgers. He even had an occasional relationship with Popeye's arch enemy, the Sea Hag.
In Big Bang Bar, the animated display for "Get Lucky" shows a four-eyed alien who's suddenly peppered with kisses by various females.
The Miz in the WWE used to call himself a Chick Magnet, to the point where one of his T-shirts includes a chick (read: baby bird) being drawn to a horseshoe red-and-white magnet, just in case some people didn't get the gist of his gimmick.
Daniel Bryan seems to be this in WWE, drawing the WWE Divas to him without even trying (or acting upon it). In one instance, he's got the Bella twins hanging on each arm.
Many protagonists of RPGs, in particular the Final Fantasy series, display this trope, with half of the female cast falling for them on sight. Final Fantasy IX plays with this by casting a childlike wannabe ladies' man as the protagonist.
Link in The Legend of Zelda: Ocarina of Time has Malon, Saria (before Link grew up), and Zora Princess Ruto all wanting him, and possibly Nabooru. The only major good-guy female character who didn't express some form of affection toward him was Impa (and maybe Zelda herself, but that's a whole other can of worms), who was more of a mentor figure than anything else. Not bad for someone who never speaks, and is essentially a 9 year old in a 16 year old's body.
In Twilight Princess, not only does he get Midna and Ilia, but the girl who runs the fishing hole seemed to have a definite thing for him. Then there's the group of fangirls he gains by making it through the clawshot minigame in Hyrule Town.
Talking to a certain chicken as a wolf in Ordon reveals that even animals have a thing for Link. There is truly no escape.
Minato, the main character of Persona 3. Minato starts off all his relationships with girls as just friends, but they quickly move things along and, whether he likes it or not, he becomes their boyfriend. His "harem" included the popular girl, the rich girl, the nerdy girl, the bookworm, the tomboy, a little girl who proposes to him, a robot, a transdimensional elevator attendant, and is essentially the subject of the affections of his teacher.
Similarly, Akihiko, who as the "cool upperclassman" type is frequently swarmed by fangirls at school. Unlike the protagonist, however, Akihiko is mostly annoyed by the attention and proves to be shy and awkward when trying to approach girls directly, to his detriment.
Tatsuya from Persona 2 is explicitly shown to be a chick magnet. Almost all the female cast wants him, major or minor characters. Even some of the guys want him.
Souji/Yu of Persona 4 is just as popular as Minato with girls (maybe even more popular). And unlike Persona 3, you can just be friends, and still max out your relationship.
In Suikoden IV, the hero also recruits an awful lot of women, and at least two cliques of three get together to gush and giggle over him. One of said cliques even declares themselves his personal bodyguards.
Random women hitting on Flik is something of a running gag. In the first game, one character only joins the group on the condition that he'll go on a date with her, and in the second he gets several more fangirls; one even has a Unite Attack with him where she breaks out in a Luminescent Blush.
Despite being a mecha otaku with no knowledge on romance with women nor interest in them, Ryusei Date from Shin Super Robot Wars has managed to make no less than three girls seriously fall for him in the Original Generation series. In the scene where the Londo Bell meets Ryusei Date during the Space Route in Shin, he manages to make Kouji Kabuto jealous of Sayaka Yumi for once instead of the reverse. This is considerably more than most other characters with the exception of Masaki, who is himself a Chick Magnet.
Clank, Ratchet's Robot Buddy from the Ratchet & Clank series has a strange habit of attracting various women, both robotic and organic. This starts with Edwina the RoboShack owner and the HelpDesk Girl in the first game, then a pink robot fangirl spends the next game chasing him over the galaxy in the next game, then in the third game, he gets to play a James bond-esque secret agent surrounded by adoring women, has pop star seductress Courtney Gears move in on him, in the fourth game, he begins a relationship with a robot called Venus (who is never seen again), in the Secret Agent Clank spinoff, all women in the game are in love with him. Meanwhile, the only definite love interest Ratchet has ever had is Sasha (Talwyn from the Future series seems to be on her way to becoming one, too, though).
Despite his nerdiness, occasionally Guybrush Threepwood falls into this. Elaine seems to initially fall for him just after hearing his name from the lookout. The ghost bride in the Goodsoup crypt starts coming onto him immediately (granted, she's been waiting a LONG time for a man). He's oblivious that Morgan seems to have feelings for him beyond typical fangirlishness. And the Vacaylian merfolk practically throw themselves at him...to his extreme discomfort, as he can't tellwhatgender they are.
Roland, the protagonist of Luminous Arc 2, weaponizes his chick magnet status by using some of the superpowers of any woman he can kiss, though he's always a little embarrassed.
The Shadow Broker's records suggests the Illusive Man is trying to be a bigger Chick Magnet than Shepard.
Guy from Tales of the Abyss. Unfortunately he also suffers from severe gynophobia and thus ends up freaking himself out every time he accidentally manages to charm a girl to take interest in him.
Flynn from Tales of Vesperia has women throwing themselves to him for as long as his childhood friend can remember. The party's Chivalrous Pervert takes him to pick up girls only to find that girls swarm over Flynn, ignoring him.
Golden Sun's Isaac has a good hint of this, having Ship Tease moments with Jenna, Mia, Feizhi, Jill (the girl who'd been transformed into a tree), and an unnamed little girl in Altin (who offers him a kiss in thanks for driving away the statue monsters).
Eternal Sonata'has Jazz, who has Claves (The mole, killed off, but can later be resurrected.) as his lover, Falsetto as the envious childhood friend, and Viola, a member of the party who falls for him as they continue their journey but can't bring herself to admit her feelings out loud to him.
The main character of Duel Savior Destiny, Taiga, is really rather popular with girls, a fact he exploits to no end. Before the story properly begins he's having a bit of trouble getting dates. That is, getting enough dates since he's working on a plan to get a hundred girlfriends at once, which is only becoming difficult because of the rumors his clingy little sister spreads.
In Chronophantasma, the Spectacles of Eros are back on Ragna's temples (literally) - this time we get Noel, Makoto, Tsubaki, Nirvana, Ignis, Bullet, Litchi, and Kokonoe in on the fun! Celica, too, but she genuinely loves him... which invokes yet another orgy of violence on poor Ragna.
To a much, much greater extent, JinKisaragi. As shown in the manga, BlazBlue: Remix Heart, he is extremely popular with girls in his Academy days. And in-game, Tsubaki, Rachel, and Makoto have expressed interests in him.
Kagura Mutsuki looks to be this, too. One of his winposes has a shapely Fox Beastkin fall RIGHT INTO HIS ARMS- And she's quite pleased about it.
The Fairies who give you Fairy Dust for the dispel potion you need to complete Quest for Glory I tease one of their number for having a crush on you (she denies it, of course). He can also flirt with the Centaur farmer's daughter.
Dinarzad the Money Changer from Quest for Glory II flirts with him heavily. And if the Hero is a Thief, so does the entire Raseir harem.
Quest for Glory III brings us the Leopardwoman Johari, with whom the Hero can share a kiss (though she agrees to marry Yesufu at the end of the game) and the Welcome Woman who runs the local inn in Tarna flirts very heavily with you, even though she's married. Some of her comments are among the most suggestive of any woman in the series.
Erana falls in love with him through her dreams if he sleeps in her garden or next to her staff. That's right, the Hero is such a Chick Magnet he doesn't even need to be on the same plane of existence for them to fall for him.
The Rusalka practically throws herself on him as well. Granted, she's a Rusalka and that's kind of what they do, but if you take the time to learn about her problems and befriend her you can trigger a Heel-Face Turn of sorts, where she admits to genuinely finding you attractive. Unfortunately, only a Paladin can complete the quest and free her to rest in peace.
And of course, there's Katrina. Originally planning to seduce and use him as a tool to further her own ends, she didn't count on actually falling in love with him, triggering a Heel-Face Turn and the first step in her redemption. Although it does lead to Redemption Equals Death until she gets better in Quest for Glory V.
Also from Quest for Glory IV, it's implied that Magda, leader of the Gypsies, finds the Hero quite attractive, though admits she's much too old for him.
Quest for Glory V manages to top them all: Erana, Katrina, Elsa von Spielberg, and Nawar (see Quest for Glory II above) are all courtable love interests. Additionally, the Hero also gets a lot of flirting from Nawar's fellow ex-harem girl Budar, Gnome Anne also shows a bit of an attraction to the Hero, and even Rakeesh admits he would consider marrying him if he weren't already married.
Adol Christin of the Ys series tends to get a good deal of female attention. One expects a wave of red-haired kids to cause trouble throughout Europa in a couple decades.
Miles Edgeworth in Ace Attorney, according to Gumshoe. His response to this is one of shock: "D-do I really inspire that sort of frothing desire in the female masses?!"
Hiroki in Canvas 2 has seven heroines, an optional sex encounter and numerous students after him. And he's completely unaware.
Yuuto in Eien no Aselia was popular at his school before ending up in Phantasmorgia, and after that he ends up winning the affections of essentially every named female in the cast.
Okazaki Tomoya of CLANNAD. Ends up with six girls in love with him, and denies that any of them are.
Riki of Little Busters is a marginal example at best: while he's surrounded by girls who like him, only one claims to have had a crush on him from before the beginning of her route, so at best there are only ever two after him at once. Instead, it's just that he's a nice guy and, as a character speculates, because he's cute and so attracts people who want to look after him.
Conversely, Kengo and Kyousuke are said to be quite popular with girls, but since neither of them are all that interested in all that it's something of an Informed Ability.
Yuuichi Aizawa from Kanon is often considered the one true capable harem leader; all 5 girls fall in love with him and he even gains the trust of the 3 supporting ones. He does not think of himself as a magnet, nor purposely tries to attract girls, nor ever notices how popular he is with the opposite sex.
Hisao Nakai of Katawa Shoujo has five very good looking women as potential love interest within only three days of arriving at Yamaku. Its a pity that he is there because of his cogential arrythmia.
Souji in Suika to the extent that random girls walking up to him on the street and kissing him is not that strange an occurrence for him.
Tsukihime: All hail Shiki! Wielder of the Tohno gland! Any female character, and any potential female protagonist, ever. The number of females Shiki hasn't charmed to some extent can be counted on one hand.
Emiya Shirou from Fate/stay night. He starts the game with at least four girls crushing at or potentially interested in him to some degree or other (Sakura being the most obvious, plus Rin, Ayako and possibly even Taiga), and as the Grail War goes on both Saber and Rider. Though she probably doesn't quite fall for him, even Ilya at least seems to find him charming or interesting in some way (though if it's mostly in the 'big brother' sense), and Caster (a declared man hater) expressed respect for him. And Issei seems to be gay for him too, just to top it off.
In Fate/kaleid liner PRISMA☆ILLYA Shirou has the unnoticed favours of Illyasviel von Einzbern, her Dark Secret Identity Kuro (think Illya in Archer fashion), their best friend Miyu and Rin Tohsaka, Sakura Matou and Luvia Edelfeldt. Also, he seems to have a questionably good relationship with Cool Big Sis Sella.
Rin in Tick Tack is noted by both Sage and Ai to be rather good at getting close to women, apparently due to the way he can give romantic seeming lines without intending to and has no apparent ulterior motives. This allows him to get close to them while Itsuki completely fails at flirting.
The Tokimeki Memorial series has a few of them, with the good-looking and popular Takumi Oosawa, Tooru Sawatari, and Jun Ebisutani in the first game's saga, and Teru Saeki, Katsumi Shiba, and Shota Amachi in Girl's Side 2.
In the original Tokimeki Memorial this is Rei Ijuin's gimmick. On Valentine's Day he has to bring a truck to school to fit all the chocolates he receives. He's actually A Sweet Polly Oliver and a winnable girl in the game.
From Funny Farm, Flink's ability to turn women (and gay men) on is inexplicable, given that he's an anthropomorphic pig. Furthermore, he's not doing anything other than standing there and talking (or just standing), and most of the time doesn't think anything of the fact that they're hanging off him. He's The Fool, but he also might be a truly asexual Chick Magnet.
"A gravitational force that draws nearly all women in his direction"
Thunderbird, in the Whateley Universe. He's gotten all the way into his sophomore year at Whateley Academy without noticing that all the girls on his training team, that girl who is always on his case about something, and that girl he thinks of as a 'little sister' are all crushing on him. Now he has Chaka after him too.
Ultra Fast Pony. Applejack mentions that her brother Big Macintosh's party was a big hit. There's a brief flashback to Big Mac atop a pile of lovestruck mares, all screaming with happiness.
Avatar: The Last Airbender has two such characters. Sokka has had four girls swooning during the series, only liking two of them back (the first didn't end well), and not even being aware of one. Zuko is also in a relationship, but this doesn't stop him from attracting two girls he has met, plus a few additional ones when he went shirtless.
In Futurama episode "The Butterjunk Effect," Fry gets sprayed with pheromones from a male alien Butterfly and becomes irresistibly attractive to women who take the "performance enhancer" known as "nectar," since it causes them to emit female butterfly pheromones. It's so strong even Amy—who is technically married to Kif—tried to have sex with him.
Despite being a Handsome Lech, Pepe LePew typically sent the female cats he fell in love with running for the hills, partly because of his skunk smell and partly because he just comes on too damn strong. On the other hand, when his odor is neutralized (on one occasion, the female cat's nose became clogged after an allergic reaction, which made her lose her sense of smell) or he gets black paint on his back which covers his white stripe (the female cats typically have white stripes painted on their backs, which makes them look like skunks), the female cats fall head-over-heels in love with him and the whole formula is gender flipped as they fall madly in love with Pepe and begin chasing him.
Mark Chang in his human disguise. His saying that any affection from him would cause him extreme pain, not knowing he's serious the girls just sigh dreamily.
Trent, Justin and Alejandro from the Total Drama series.
While any crushes in The Magic School Bus are only hinted at, geeky guy Arnold seems to get Ship Teased with other female characters the most, including Phoebe, Wanda, Dorothy Ann, and a one-shot character named Tiffany.
A lot of princesses from Adventure Time have shown romantic interest in Finn, but being the Last of His Kind means all of the girls are either dogs, elephants, slugs, cloud-like lumps, etc. The only femalehe is genuinely interested in doesn't reciprocate. Fortunately, after three seasons of being unlucky in love, he meets Flame Princess, who does feel the same way.
Rex from Generator Rex has so far attracted the attention of at least four girls that were significant to the plot in one way or another.
Ben 10: Max Tennyson. Bonus points in that at least two of 'em (Xylene and Verdona, the latter of whom is Ben and Gwen's grandmother) were extraterrestrials. Even better, he's still got it even as an oldman. And it's implied that that's not even the full story!
Ben himself wasn't one in the original series, but the sequels, especially Ultimate Alien and Omniverse, allow him to get some as well. By now, he has attracted the attention of Julie Yamamoto (until they decide to move down to "just friends" in Omniverse after ironing out an unintentional break-up on Ben's part between UA and Omiverse), Eunice, Elena Validus, Jennifer Nocturne (though for publicity), Ester, Princess Attea, and even ended up accidental fiancé to a Tetramand princess. It seems he has more luck attracting aliens than he does human girls, like his grampa (Rook even asks how many girls Ben has in his life during "Rules of Engagement", to which Ben replies he has no clue). Oddly enough, Kai Green, the one girl Ben went out of his way to try to impress and woo, had no interest in Ben whatsoever until he slowly started mutating into Benwolf/Blitzwolfer, and that was only because she wanted to tame him. (Unless you take into account the "Ben 10,000"/"Ken 10" alternate universe seen in the original series, as Word of God states that the Kai of that timeline is Ben's wife and Ken's mother.) And even that is starting to reverse as of "An American Benwolf in London", as while Kai still prefers Blitzwolfer, she gets flustered when people imply she and Ben are a couple and gives Ben a kiss on the cheek as they part ways.
Ben is stunned to find out that Rook was one of these on his home world.
Bob from ReBoot. He attracts Dot, Mouse, and Hexadecimal along with other minor female characters.
Much to the surprise of everyone, Dizzy Devil from Tiny Toon Adventures had a knack for attracting beautiful women, even when he wasn't trying.
Corey Riffin from Grojband, as a result of being popular.
Frank Sinatra. Looney Tunes featuring of him frequently had the members of his audience fainting, sighing "Oh Frankie!" in ecstasy, going into seizures, or screaming. They always chased after him in huge crowds once he was done performing. More or less the same things happened to The Beatles.
It has been claimed that poet/artist/songwriter/Renaissance ManShel Silverstein had to beat the ladies off with sticks. Not a perfect example, as he wasn't at all "innocent" about it.
Doug Walker. Even at his second ever con, he had women telling him they want to take him home and keep him. He's grown to use both this and Even the Guys Want Him to his advantage, but the amount of marriage proposals he gets seems to make him uncomfortable.
Anime and Manga
The title character of Miyuki-chan in Wonderland attracts the attention of everyone in the worlds she stumbles in, since they're all inhabited by girls only.
Futari wa Pretty Cure: Honoka is noted to get love letters from boys all the time, and poor Nagisa is chagrined that she gets them from the girls all the time.
Hayate the Combat Butler: Hinagiku. Apparently everyone in the school likes her. Lampshaded several times, and once by the title of a chapter, "Are you a magnet or something?"
Yuria, Kenshiro's one true love from Fist of the North Star, is sought after by a significant portion of the cast for one reason or another; most memorably by Shin, but even big scary Raoh fell for her hard.
Akane Tendo is wanted by Ranma, Ryoga, Kuno, the entire school, etc. It isn't until it's confirmed that Ranma is Akane's fiancée that the school gives up on trying to woo her.
Also, Ranma'sfemale form. Those who don't know she is a he pursue her. Those who do openly ogle.
Natsuru from Kämpfer only starts attracting females after his gender-bending transformations; even the ones interested in his male form weren't interested before. Though more girls want the female Natsuru, the male version gets this reputation amplified when rumor goes around that he has a secret affair with the female Natsuru.
Kyoko from Maison Ikkoku. Like Yusaku, she's a less exaggerated example of this trope due to the nature of the story.
Celty of Durarara!! has had people fall in love with her headless body (it is a very nice body), as well as with her severed head.
Mikan of To Love-Ru also seems to be a Dude Magnet, and is continually being asked out by the boys in her class. Unfortunately for the guys, she's a Bro-con in denial. It seems the Yuuki family is God's gift to the opposite sex.
Chiba from Wandering Son is a Dude Magnet. Few straight boys her age in the series have not taken a liking to her at one time or another.
Momo from Peach Girl has about four guys after her at one time or another.
Like her brother, Natusumi Hinata of Keroro Gunso has quite a following. Only it seems to be of the same gender. From her swooning all girl fanclub at school, to Koyuki, she's a real draw for chicks. The only male that seems to have any interest in her, is Giroro.
THE iDOLM@STER - More of a Fangirl Magnet, but otherwise fits Makoto to a T.
Miki is pretty skilled at attracting the guys without trying. This is actually part of what leads to her Brilliant, but Lazy attitude.
Sena Kashiwazaki from Boku wa Tomodachi ga Sukunai is often followed around by a gaggle of guys tripping over themselves to do favors for her. She couldn't care less about them, though — she's only interested in the one guy who stood up to her.
Ghost Talkers Daydream: Misaki has at least three different guys crushing on her between: Kadotake, Mitsuru, who's been stalking her ever since she turned him down as a client, and Kobayashi, who's one of her office co-workers. Plus, she's one of the most frequently requested Doms at the Roppongi S&M Club, and a magazine company once asked her to offer a pair of her panties as the first place prize for one of their contests!
Jessica Drew's Spider-Woman, thanks to her power which has a side effect of attracting men.
Marvel Star Wars: Zeltrons are drawn to◊ Leia Organa just as they are to her brother, and for the same reasons - she's heroic, famous, and Force-Sensitive.
Supergirl has to deal with guys literally falling off buildings so she'll rescue them - and hopefully give them her phone number afterward.
Fred was a bit like this in Angel. It took her forever to notice that both Gunn and Wesley liked her, plus Amy Acker apparently got quite a lot of attention on set as well. Characters who have been attracted to or Ship Teased with Fred or Ilyria are Angel, Angelus, Wesley, Gunn, Spike, Knox, Connor, and Willow.
Annie in Being Human. Tully and Gilbert from Season 1; the Love Triangle with Hugh and Saul in Season 2; and now Mitchell in Season 3.
In one episode of How I Met Your Mother, "The Window", Ted recalls his longtime crush Maggie whom he never got to date because, as he describes her, she is "catnip for men".
This puts off Robin, who considers herself the alpha female in this department. "Your friend may be one of those magnets that can hold up a picture of your kids on the fridge, but I'm one of those magnets that can pick up cars in a junkyard!"
Spencer Carlin from South of Nowhere is possibly the best example of a lesbian chick magnet. She has no problem attracting girls without any effort
Friends: Rachel and Phoebe both pick up numerous guys with ease.
Samantha Carter from Stargate SG-1 is almost as much of an example as Daniel, with multiple love interests and explicit and implicit interest from dozens of men, including an Ancient and a Replicator.
In one episode of Seinfeld, Elaine becomes a Shiksa Goddess and has every Jewish man she meets fall in love with her, including a boy at a bar mitzvah, his father, their rabbi, and even Jerry.
Asellus of SaGa Frontier is a rare video game example of this (still attracting girls, not guys), and there's a in-story reason for it to boot. She has the blood of the Charm Lord in her, which makes her half-mystic, but also gives her the Charm Lord's Innate abilities of seduction and attraction to females. If you see the Easter Egg, you'll understand more.
Surprisingly, Tali gets almost as much attention from the guys as female Shepard. She's one of only two recurring squadmates who can end up with a love interest who isn't Shepard (namely, Garrus, the other squadmate), and she draws positive attention from Joker, Kenneth, Kal'Reegar, and even Javik in a way.
The female protagonist of Persona 3Portable. Junpei (the only male in SEES she cannot have a romantic relationship with) notes that a number of guys he talks to are interested in her. At least two of her Social Links develop feelings for her, although she can't have a relationship with them, another one calls her beautiful, and she is able to (optionally; the game developers have realized that it is possible for boys and girls to just be friends) romance Akihiko (himself a Chick Magnet), Ken, Ryoji, and Shinjiro who is implied to have fallen for her whether the player chooses to become lovers with him or not. Then there's Theo and Aigis...
Kaine from A Profile, which is funny considering he's not even the protagonist. He actually gets more attention from girls than Masayuki does. But if it wasn't for the fact that Masayuki hangs around with Miou, a suspected prostitute, he would get even more attention.
DiDi of Ménage à 3 has nigh-supernatural sex appeal (and not just because of her astonishingfigure), to and beyond the point of being Blessed with Suck; as a result, she not only has so many boyfriends she can't keep count, she frequently distracts every male in line of sight.
Parker Kovak IS this trope! Men, women, infants, robots, computers, and more have all had at least some romatic interest in her.
The Lance Nine Trillion in his sole episode of Time Squad is a literal example of a dude magnet. This is also true of his human coworker, J.T. Laser, but only Lance actually attracts his adoring fanboy (the Larry 3000, in this case) magnetically.
An episode of Aqua Teen Hunger Force has Shake buying a literal Chick Magnet. It ends up feminizing those in its aura.
