A common observation in fiction: Once you get a girlfriend, other girls just come naturally.

The lead male character may be [[NiceGuy nice, kind]], and fairly attractive. He may adopt stray kittens, help old ladies across the street, do charity work in Third World countries. It doesn't matter, because he's never, ''ever'' going to be able to find a girlfriend....at least, not until a girl swoops down out of nowhere and [[TheGlomp attaches herself limpet-like to his arm]].

Suddenly he has an embarrassment of riches. Girls who wouldn't even look at him before are now beating down his door. Old acquaintances he can't even remember will appear and claim to have loved him for years. He can walk down the street and have new characters pop up claiming LoveAtFirstSight.

This can also happen even when the girl is still only a LoveInterest, which makes it even harder for the guy to beat off the other girls and convince her that she's his One Twoo Wuv, ([[FirstGirlWins which she is.]]) It also makes it harder for him to beat off in general, but that's another story entirely.

As a part of the wish-fulfilment element that defines the HaremAnime genre, the MagneticGirlfriend will ''not'' be jealous of the other girls that enter the equation. This is because she is either too naive to notice their affections, so nice that she would rather be their friend than their rival, or that she trusts her boyfriend to not cheat and so doesn't feel threatened by the extra girls. Oddly enough, her upbeat and kind personality is usually enough to win over their friendship, but the race for the guy is most definitely still on.

Note that if the MagneticGirlfriend is somehow detached, her effect will often wear off. If the magnetic effect is unnecessary, the guy is a natural ChickMagnet.

Compare OperationJealousy where the same 'attraction of the unavailable' is at work.

TruthInTelevision. Sometimes, the experience of getting a girlfriend gives men newfound confidence that makes them more attractive to other women. Sometimes, the fact that a man isn't on the hunt anymore makes them more relaxed and natural and thus less awkward. Finally, the fact that he has a girlfriend signals to other women that there is ''something'' desirable about him, an effect which in RealLife is called "pre-selection" or "social proof." There's also a belief that after having sex, a man releases pheromones that make him more desirable (again going back to the proven desirable'' mentioned above.) This may or may not bode well for the relationship.

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* Keitaro and Naru in ''Manga/LoveHina''.
* Belldandy and Keiichi ''Manga/AhMyGoddess'', respectively. Keiichi's pseudo-[[TheRival rival]] is only vaguely interested in Bell because she ''isn't''. Sayoko is arguably less interested in Keiichi than annoyed at Belldandy stealing away most of the attention from her classmates, as well as the protective nature of Bell and Kei's wish causing problems for anyone intruding on them.
* ''Manga/AiYoriAoshi''.
* ''Manga/NagasareteAirantou'' almost fits this trope to a T. The magnetism, however, is due not to the guy getting a girl, but to the fact that the guy is ''the'' guy -the only human male on the island. HilarityEnsues.
* ''MidoriNoHibi'' takes this to extremes - Midori is not only both figuratively and ''literally'' attached to Seiji, but her appearance on his right arm sparks a run of luck where quite a few women (and one slightly nerdy boy) fall for Seiji. Justified as Seiji was an JerkAss before Midori started forcing him to change his ways. If it wasn't for Midori, Ayase would have been gang raped, Lucy would have lost her purse and be stuck in Japan, etc.
* A mild version happens in {{Seinen}} manga and Anime ''Manga/YumeDeAetara'' (aka ''If I See You In My Dreams''). The wimpy Masuo Fuguno falls in love with the beautiful Nagisa, and suddenly a lot of women began to insinuate/try to seduce/trip on him scantly dressed/fall in love with him. Masuo, being a man with no romance experience, doesn't know how to cope with this or convince Nagisa that [[AccidentalPervert everything is an misunderstanding]]; and Nagisa, being almost as inexperienced as him and a bit of {{Tsundere}}, doesn't believe him and gives the cold shoulder. Notorious because, even with this setup, ''doesn't'' become an harem series.
* A running gag in the early ''Manga/VideoGirlAi'' manga and anime is that Youta Moteuchi's name, if you mispronounce the kanji as "Motenai Yo Da," means "Dateless." He did everything in his power to be noticeable, even buying magazines for tips. Once he met [[spoiler: and lost]] Ai, however, everyone from his UnluckyChildhoodFriend, to the GirlNextDoor, to a former classmate who had a crush on him [[spoiler: as well as an amnesiac Ai,]] falls head over heels for him.
* Lala, Rito's [[MagicalGirlfriend Magical Alien Fiance]] (of sorts), from the ''ToLoveRu'' manga. Before he met her, he was pretty much just some average guy [[CannotSpitItOut who can't admit his crush]] on an old friend ([[TwiceShy who apparently also has a crush on him that he isn't aware of]]). After meeting Lala, however, a series of events is set off that sees him unwittingly gathering an UnwantedHarem.
* ''TenchiMuyo''. Poor naive Tenchi frees Ryoko from her prison, where she has been locked for 700 years. Within a matter of days five or six more show up and almost all of whom are capable of blowing up his house at minimum, the planet at maximum.
* Himari of ''{{Omamori Himari}}''. All the {{Cute Monster Girl}}s (and one {{Dark Magical Girl}}) seem to have come out of the woods right after Himari entered Yuuto's life, although that may have more to do with [[{{PubertySuperpower}} the awakening of his demon-hunting powers when he turned 16]].
* ''{{Negima}}'' has an...interesting take on this; when Negi asks to speak to Ku Fei after class, a bunch of the other girls automatically assume he likes her and begin making their own attempts to win him. Of course, after they all work themselves up over it, it turns out that he wanted learn martial arts from her.
** It also happens in a more traditional sense. Nodoka confesses to him, and explains to the other girls that she likes his maturity and determination. Cue numerous other girls beginning to be attracted to him for the same reasons. Up to and including ''[[RobotGirl a robot]]''.
* Touma in ''LightNovel/ACertainMagicalIndex'' is a subverted example. It's stated that his teacher and all of his classmates, and a great many other females, are attracted to him, or at least find him cute because of his bad luck, before Index comes along.
* Discussed in ''LightNovel/SpiceAndWolf''. A barmaid tells Lawrence that having a beautiful "companion" (who even went to the effort of marking him with her scent) makes him more desirable.
* ''Manga/RosarioToVampire'': NiceGuy Tsukune gets a girlfriend on his first day at [[AllGhoulsSchool Yokai Academy]], the [[SoBeautifulItsACurse incredibly gorgeous]] and [[OurVampiresAreDifferent friendly vampire]] girl Moka Akashiya. Its not long before several more girls fall for him: A [[BuxomIsBetter big-breasted]] [[HornyDevils succubus]], a [[CuteWitch young witch girl]] who [[EvenTheGirlsWantHer also has a crush on Moka]], a [[DefrostingIceQueen yuki-onna]] who's a StalkerWithACrush, and another, [[HotWitch older witch]] (though she's not too crazy over him like the others are).

[[folder:Literature]]
* When the usually-isolated Utahraptor packs of ''RaptorRed'' are brought together by a field of carrion-scented flowers, Raptor Red's consort, ''being'' a consort, attracts the attention of other raptor females, forcing Raptor Red to fight for him. The consort himself isn't exactly thrilled by this.

[[folder:Live Action TV]]
* This happens to JD in ''{{Scrubs}}''. In the course of an episode he goes from dateless, to having a girlfriend and back, while a random woman in a bar follows this to a tee.
* Also happens to Mike in ''Series/OffCentre''. It's actually lampshaded and later subverted when he then tries to cheat on his girlfriend. The girls that were all over him suddenly hate his guts.
* This happens to Dean in the season 6 premiere of ''Series/{{Supernatural}}'': he's wearing a wedding ring (although he's not married, he is shacking up with someone at the time) and a waitress at a bar gives him her phone number along with the check. Dean lampshades it to his buddy that he's in the bar with[[spoiler:, but [[SubvertedTrope it turns out]] it's really a demon trying to get him alone so she can kill him.]]
* ThirtyRock based a whole episode on this, and called the phenomenon "when it rains, it pours."
[[/folder]]

[[folder:Webcomics]]
* In the webcomic ''YuMeDream'', once everyone knows Fiona is a lesbian, [[spoiler:they kiss her or threaten her to stay away from "their girl"]].
* Kevin makes this observation in ''WapsiSquare'' [[http://wapsisquare.com/comic/justweird/ here.]]
* Nancy in ''Webcomic/OwMySanity'', for unusual (but perfectly logical) reasons.
* Tai of QuestionableContent has an [[http://www.questionablecontent.net/view.php?comic=1322 interesting theory]] on the phenomenom.
[[/folder]]

[[folder:Western Animation]]
* The episode "[[http://dcanimated.wikia.com/wiki/Terry%27s_Friend_Dates_a_Robot Terry's Friend Dates a Robot]]" of ''WesternAnimation/BatmanBeyond'' has a nerd who (successfully) attempts to emulate this effect by purchasing an illegal android girlfriend. He's instantly considered more popular, and girls who already have boyfriends offer to "double date" with him. Needless to say, things go bad by the end.
** That is an understatement, given her [[ClingyJealousGirl obsessive and jealous personality]] and the UnstoppableRage she flew in when he suggested they "see other people." Not even Batman could save the house.

[[folder:Theater]]
* The song "Temptation" from TheLastFiveYears:
--> ''"Everyone tells you that the minute you get married, every other woman in the in the world suddenly finds you attractive; well, that's not true. It only affects the kind of women you always wanted to sleep with, but who wouldn't give you the time of day before, and now they're banging down your door and falling to their knees, or at least that's what it feels like, because you can ''not'' touch them..."''
