Rather than requiring someone to pick one person out of several potential love interests, or adultery, all parties involved agree to be together and share cooperatively. This typically lacks any drama of the decision itself, but has a different form of drama in how people make arrangements with each other, manage jealousy and households, and deal with the disapproval of society as a whole.
Individuals who identify as polyamorous may consider themselves "Ethical Sluts". Not all ethical sluts are polyamorous, and not all people in polyamorous relationships have the "ethical slut" attitude. The difference between a polyamorist and a swinger is that a polyamorous person has broad-spectrum involvement in their partners' lives, including love. Swingers are largely there for the sex, often for the novelty of an unfamiliar partner.
- Exotic Extended Marriage, when polyamory/non-monogamy is normal, if not the norm, for a foreign/nonhuman culture rather than a fringe practice.
- Marry Them All, when a Love Triangle or Love Dodecahedron is resolved by coming to this conclusion.
If it's just hinted at, it's Threesome Subtext. If it's not canon but fans ship it, see One True Threesome. If it's just sex, not full-on relationships, see Three-Way Sex. If one partner receives preferential treatment over the others, then the former is Top Wife and the latter are a Supporting Harem.note
Not to be confused with Polyarmory. Polygamy is a subtype of polyamory, as it means more than one spouse, while with polyamory, marriage and dating both count. Though real life polyamorists try to disassociate these two as the word "polygamy" has some messy implications.
For more details and some Real Life tidbits, visit Useful Notes On Polyamory. Truth in Television, obviously, though how culturally accepted it is varies wildly depending on the place, time period, and social standing. Currently, polygamy is Banned in China (plus all Western countries), but still legal in some parts of Africa and Asia. note
The late New Tens has witnessed the growth of the Reverse-Harem (RH) genre in romance and urban-fantasy literature.
- The 100 Girlfriends Who Really, Really, Really, Really, Really Love You revolves entirely around the protagonist gaining 100 soulmates, all of whom love him and are perfectly willing to share him.
- Cross Marian may be a practitioner of this. He has many lovers. We met one—Anita, and heard of another, which was her mother. Both seemed to love him, and want to help him. They support the Dark Order just to do something for him. He is apparently a good lover, and he seems chivalrous in general when it comes to women. He hates the Order, and has been hiding from them for 4 years, but stayed because Lenalee asked him to, which exposed his Fatal Flaw. Earlier he protected Lenalee on the crumbling ark. Word of God states he likes "good women." Apparently, he cares for his lovers outside of sex, otherwise whether or not they're good women probably wouldn't matter. And he isn't unethical about it, as Word of God lists his dislikes as "dirty bastards." Allen states that Cross lives with, and off of, lovers in different places. So, apparently, it's not just Anita and her mother that care enough to do things for him. Anita and her mom were also prostitutes, but Cross stated the former as a good woman when he finds out she's been killed.
- Also, a scene in Jump SQ seems to hint at this. Allen visits Mother and Ba Ba's house, and he says underneath Cross' bed is filled with things he got from his lovers. We see, in his room in chapter 167, he has at least five pictures on his shelves, possibly pix of some of his lovers. So he apparently hangs on to things his lovers let him have.
- Dual! Parallel Trouble Adventure: An Alternate Universe of Tenchi Muyo from the same creator, Kazuki Yosuga likewise ends up with all four of his romantic interests in a 3rd new reality, created by combining the previous 2 parallel worlds. The twist? It was created by the will of the formerly Clingy Jealous Girl Mizuki S. when she realized that Kazuki loved all of them equally.
- Rokujo Chikage, Durarara!!'s resident Ethical Slut and Chivalrous Pervert, is happy to be with any girl that doesn't mind sharing. The series introduces him dating eight girls at once.
Girlfriend 1: Why are we dating such a playboy again?
Girlfriend 2: Because it's one of our weird hobbies.
- Proposed as a solution in Girl×Girl×Boy although it gets rejected in the end.
- In Gunota ga Mahou Sekai ni Tensei Shitara, Lute winds up married to two girls, and it's not his idea, but theirs. He loves them both equally, and despite the marriage being officially recognized in-universe, it is treated as rather odd by those who hear of it.
- The relationship drama Hare-Kon features a "one-man-multiple-women" situation as a growing practice for the female lead's district in Tokyo, and only there for the time being. Harem marriages, or "Hare-kons", are typically marriages of one guy and a maximum of four women, encouraged due to lowered birth rates. The protagonist Koharu finds herself in a four person Hare-kon, but the series picks apart how stressful the situation can be, the jealousy and infighting that crops up, and how all the members contribute to the family dynamic.
- High School D×D is based around this trope. Initially set up as a traditional Harem Series, it deviates from the norm because none of the girls care that the others like him too; in fact, several of them actively help the others get closer to Issei, culminating in the rest of the harem helping Issei and Rias become an Official Couple. At least two of them stated that they were waiting for this to happen before they went any further with Issei themselves. And for her part, Rias has no problem with polygamy as long as she's number one.
- The Ideal Sponger Life: Has an interesting case where the main character, Zenjiro, is happily married towards the Queen Aura, and would rather stay married to her than take on concubines. However, due to the politics revovling around Kings taking a wife and multiple concubines, he has no choice but to take on them other than Aura and her country would suffer from his actions despite his desire to be with her only. Even more that Aura herself is the one who (reluctantly) pushed this on him despite trying to honor his request due to her love for him, but he agrees to avoid trouble for her on the condition she's the Top Wife. He takes on from the Northern Continent Princess Freya and her bodyguard Victoria as a concubine in volume 12 of the series.
- If Her Flag Breaks: Not only do none of the girls (and one boy) in Souta's harem ever show signs of jealousy, when directly asked who will marry him or bear his children in the future, many of the girls (especially Akane) offer the honor to a girl that they feel would be better suited or would make cuter children. Even when they're all separated by the destruction of their virtual world at the end, they all rejoin Souta in Quest Dorm in the finale.
- Her Royal Majesty Iono from Iono the Fanatics somehow manages to be in a romantic relationship with an entire kingdom worth of Schoolgirl Lesbians. And satisfy them all. Unless, of course, she is traveling abroad, in which case her paramours start a civil war, with one fraction believing in her eventual return and the other striving to bring her back by force.
- This is basically the conclusion of the borderline hentai manga Kanojo De Ippai when all three main females agree to share the male protagonist since they all like him, and end up living under the same roof without much issue.
- In Kanojo Mo Kanojo, Naoya starts dating his childhood friend, Saki Saki, then receives an abrupt confession from Nagisa Minase. Unable to hurt Nagisa, or betray Saki, Naoya thinks up a "solution" to make both girls happy by dating both of them at the same time.
- Done with after the credits in the anime's Gecko Ending—Chizuru wins, and Nozomu is Put on a Bus but wait, she returns after the credits and they decide to share Kouta. Which kinda sucks for him, as both of them are extremely oversexed yōkai (Japanese demons), and he's mostly Asexual. Of course, he doesn't get a say in the matter.
- It's also done part way through the manga, where after Kouta tells Nozomu he loves Chizuru, she leaves then immediately comes back and declares herself his lover. Chizuru's reaction is basically "Gah, whatever, I'm still number one." However, while Kouta's opinion is not asked initially (like the anime) he later declares he loves them both and is going to be faithful to them both and no one else.
- Kiss and White Lily for My Dearest Girl has an arc centered around this in volume 6, where a girl named Amane believes that you dont have to restrict yourself to loving one person, while a girl named Ryô falls in love with her and Amanes girlfriend Nina has trouble accepting her peculiar vision. They all end up forming a relationship in the end.
- YasaKan has this as its central plot, with the story starting as a love triangle between middle-schooler Mayuki, who wants to get in the same high school as her beloved senpai Akira, who is in love with her own friend Rin, who is herself in love with Mayuki, for whom shes a private tutor. The drama of the first two volumes is about Rin and Akira wanting to form an exclusive bond with their respective crush, while Rin was scarred by her past experience of loving two girls and being unable to "choose" one. After some developments though, they end up accepting a shared relationship at the end of chapter 10.
- Maoyu, while not flat out stated that the three are romantically involved together, the fact that the Light Novels end with The Hero, The Demon Queen and Lady Knight deciding to retire and leave together, with no one else in tow, to live in some faraway place in peace, sure says something, especially since both girls had previously come into terms that they love The Hero.
- Marmalade Boy: Jin and Rumi Koishikawa, and Youji and Chiyako Matsura (later Jin and Chiyako Koishikawa, and Youji and Rumi Matsura) seem to hint at this. Swapping spouses is one thing; all moving into the same house together and spending all their free time together awfully suggestive.
- Mobile Suit Gundam: Iron-Blooded Orphans:
- Naze Turbine has a Cool Starship, which is entirely crewed by his harem. All of the women appear to be okay with the arrangement, to the point that children are communally raised. We are shown five very young kids on board the ship, each from different mothers, and it's mentioned that Naze has more, older children back on the space colony he calls home. The second season clears things up a bit, explaining that while Naze did legally marry all the women on his crew, it was more about recruiting talented, capable women and getting them away from the crappy menial jobs they were stuck in thanks to scumbags who looked down on them because of their gender. He also only slept with the women who came to him, not pursuing any of them who didn't actually want a physical relationship. Naze himself outright says that he actually views the girls more as daughters than wives, and when Lafter begins showing romantic interest in another man, he's fully supportive of it and glad she's found someone she truly loves.
- After meeting the Turbines, Atra gets the idea that maybe she and Kudelia could share Mikazuki instead of competing over him. In season 2, Atra first confesses to Mika, then gets Kudelia to join their relationship.
- Negima! Magister Negi Magi:
- It turns out that Nodoka views this as an acceptable solution to the Love Triangle between herself, her best friend Yue, and Negi, showing up in her ideal world. The sequel reveals that she and Yue actually went through with it (in the UQ Holder timeline anyways. In the timeline seen at the end of Negima he marries Chisame).
- Luna aka Shiori's own ideal world shows that she wouldn't mind having both Negi and Fate.
- In Nyaruko: Crawling with Love! Cuuko proposes one between her, Mahiro and Nyarko, after she warms up to Mahiro, suggesting "I bear Nyarko's child, the boy bears mine." Unsurprisingly, neither Nyarko nor Mahiro are really down with this idea.
- One Piece: The world nobles practice extensive marriage, but given that they can ignore laws it also doesn't suggest if this is legal or not. These relationships are hardly healthy however given that many of the wives are grabbed off the street and dismissed whenever the male world noble grows tired of them.
- Pokémon has Brock sing a song about how much he wants this with Jenny and Joy.
- Psyren has Ageha/Sakurako/Abyss.
- Used in Red River (1995), crossing with Twin Threesome Fantasy. Yuri's handmaidens Ryuhi and Shala both like Kail's advisor Kikkuri, and they bed him separately. They both get pregnant. Kikkuri had believed he was sleeping with one of the girls, but instead of "choosing" he marries them both. At the end of the story, the girls have given birth to twins! (Ryuhi has two boys, Shala has two girls). They all live more or less happily under the same rooftop.
- Rosario + Vampire, where the entire harem wants this situation except for the first girl, who doesn't want to share (though said girl is two for the price of one and might count just by herself). The boy hasn't made his views known.
- Sayonara, Zetsubou-Sensei has a rather complicated example of this. Nozomu loves the First Girl, Fuura Kafuka. However, it's revealed in the final chapters that she was Dead All Along. Her organs, however, went to the girls in Nozomu's class, causing him to see her in his students one at a time. (As his sister Rin puts it, he's in love with her corneas-in Abiru-then her lungs-in Komori-then her heart-in Chiri.) On paper, he's in an endless cycle of marriage and divorce between the girls. In Nozomu's eyes, he's married to Kafuka and Kafuka alone. To outsiders, it looks like this trope, especially since all the girls have children by him (that eerily look like Kafuka).
- Sekirei: When having multiple Sekirei, when they get winged is considered "marriage" for most. But for most Ashikabe's features them favoring one over the other with them hardly having healthy relationships for the sake of having multiple women in their lives. For the protagonist Minato however, he breaks away from this. As he ends up having 6 in his harem (1 being a child and the other being a man while the other 4 are beautiful and buxom women), he effectivally fits the Marry Them All trope upon the epiloque with him loving and treating everyone in his harem equal. Even more is that all his Sekirei all love him unconditionally and are happy to share him as their husband.
- Chocolat/Carrot/Tira was almost canon in Sorcerer Hunters, and some fans still would have preferred that to the manga's actual ending. Then again, Chocolat did end up with Carrot's kids
- Tenchi Muyo!: Seina slips into this trope at the end via a Marry Them All resolution, though it still has the feel of the former, and Word of God says Tenchi himself fits this trope. In both cases, it helps that they're in line for the throne of Jurai (Tenchi being the Crown Prince), a position that, as far as we can see, traditionally comes with multiple wives (the current one has two). It also helps that the Jurian equivalent of the Queen Mother fancies herself a matchmaker, is a master of The Plan, and seems to prefer this outcome. Word of God shows this also happens between Seina's oldest son and Ryoko and Ayeka's daughters, as well as Seina's second son and Ryo-ohki's three daughters, and Seina's youngest son and Mihoshi and Noike's daughters.
- The High School A.U. manga of Tengen Toppa Gurren Lagann features Simon/Nia/Dark Nia in its ending (Dark Nia in this version is a secondary persona/imaginary friend that Nia created from being denied any friends by her overprotective father).
- The last chapter of To Love-Ru hints that this might be a viable option for Rito; at the very least, Lala is enthusiastic about to the point that it seems to be her preferred option. In the sequel, To Love-Ru Darkness, one of the girls tries to open up this route (Lala approves), and is only hindered by Rito's belief in monogamy.
- Tsugumomo: The ability to share Kazuya is hinted at multiple times by the girls, especially since some of them are bisexual. Their main point of contention mostly seems to be who will be the first to "deflower" him and share other intimate "firsts" with him. But beyond that, there's little attempt to hoard him for themselves.
- Umi no Misaki ends with Nagi and his three girls in this agreement. The epilogue chapters show that the four of them are getting along perfectly well despite the oddity of their relationship.
- In Demon Knights, Jason Blood and Etrigan are two beings who were magically joined together by Merlin, and who are each married to Madame Xanadu. It sort of works because only one or the other can inhabit the human plane of existence at a given time; the one who isn't on the human plane ends up in Hell during that time.
- ElfQuest. Many of the elves end up "lifemating" with two others, and their relationships are generally loving and long-lasting (and in at least three cases, explicitly mentioned as a sane alternative to jealousy and rivalry). Problems tend to arise only with Recognition, a form of "love"/lust based entirely on involuntary instinct. Examples: Leetah/Cutter/Skywise, Skot/Krim/Pike, and Dewshine/Scouter/Tyleet.
- A DC Elseworlds story, "Superman/Wonder Woman: Whom Gods Destroy", written by Chris Claremont, is set in a world where Superman made his first public appearance in the 1930s, when he met Lois Lane. Cut to the present day, where Lois Lane and Lana Lang are in their seventies and are very close friends. Despite Superman's presence during WWII, the Nazis are still in power in Germany, due in part to the interference of Ares and several other Greek Gods. Another faction of Greek Gods, led by Artemis and Athena, grant Lois and Lana eternal youth and superpowers (Lana becomes the Oracle of Delphi and Lois becomes Wonder Woman; Diana had turned traitor and joined the Nazis in the interim), and they team with Superman to defeat Ares' faction. Part of Ares' plan is to separate Clark from Lois and Lana, since their powers somehow bind them together. When Lana explains to Superman, "Ares doesn't want the two of you together," (referring to Clark and Lois), Hecate, the Greek witch-goddess, corrects her, "No, the three of you." By the end of the four-issue arc, Clark, Lois and Lana are happily living together in his Fortress of Solitude (the now young Lois changed her name to Lois Lang) in a polyamorous relationship.
- The Incredible Hercules establishes that besides being The Casanova who beds any number of women he can, Hercules has several steady girlfriends all over the world. After his death at the end of the series, Venus and Namora find this out when they visit houses or businesses that Hercules has bought or built himself, each of which houses or employs a woman who loves Hercules and is shattered and heartbroken by his passing.
- In League of Extraordinary Gentlemen Century, Mina, Allan, and Orlando are in a somewhat complicated polyamorous relationship. It's complicated because Orlando's a Gender Bender, and Mina doesn't seem to enjoy his company so much when he's male.
- In the last issue of the Secret Six ongoing, Scandal Savage decides she can't choose between her girlfriends and proposes to both of them at once. It's implied that they did marry, as in later stories Knockout reaches for Scandal's hand and whispers "Wife...", and a villain taunted Scandal by threatening to harm her "wives".
- Strangers in Paradise: Francine, David, Katchoo, Casey, Freddie and even Tambi all alternate between being friends, enemies, sexual partners and various places in between, and also rotate living with each other as one or more of those options. After David reveals to Casey and Katchoo that he is dying, they all (well, most) decide for Katchoo, Casey and David to form a sexual relationship in order to produce a child and because they all do love each other, even though Katchoo only really loves Francine, David only really loves Katchoo, and who Casey really loves is more complicated than even the reader thinks at the time. Once David dies the series settles down into Katchoo-Francine and Casey-Tambi (!?!?!?!?!?), though even then David sticks with both pairs in spirit and via his child with Katchoo.
- At the very end of Superman: Red Son (an Elseworld), when Lex Luthor uses his genius to turn Earth into a utopia, it's said that the "triple" replaces the "couple" in human relationships.
- The Norns in The Wicked + The Divine are in a closed, triadic relationship, with Urdr/Cassandra submissive to Verdandi and Skuld.
- A common theme in erotic comic XXXenophile, created by Phil Foglio, (who later went on to do Girl Genius, which also has an entry on this page).
- In Jonathan Hickman's X-Men, Jean Grey, her husband Scott Summers, and teammate Wolverine are depicted as being in a polyamorous relationship. This was first hinted at with a map of the Summers household showing Logan as a permanent resident, with Jean's bedroom in the middle of her husband's and Logan's, with their rooms connected by hidden doors. Later comics would show Jean having explicitly romantic and sexual encounters with both Scott and Logan.
- In one Dream of the Rarebit Fiend strip, a man dreams that he has joined the Mormons and married ten women. He wakes up just as they're attacking him to get their share of his weekly paycheck.
- Played for laughs in The Marx Brothers' Animal Crackers, when Captain Spaulding jokingly proposes to two women at once.
Mrs. Rittenhouse: But that's bigamy.
Captain Spaulding: Yes, and it's big of me too. It's big of all of us. Let's be big for a change.
- Bandits has both the main characters falling for their hostage turned ally. When she is pressed to chose she deliberately chooses "not to chose," and is last seen happily with both of them in Mexico.
- Nearly happens in Bob & Carol & Ted & Alice. Just as it seems like this will happen, with all four of the principals in bed together, they change their minds.
- Love Songs: Julie and Ismaël resolve Ismaël's attraction to his coworker Alice by forming a ménage à trois which doesn't survive the first act: when Julie dies, Alice and Ismaël go their separate ways.
- Der Philosoph: Georg the academic is delighted to get a sexy girlfriend, Franziska, but is a little bit startled when Franziska's two hot roommates also start making overt sexual advances towards him. When he finally tells Franziska, she reveals the truth: the three of them are immortal beings that have taken an interest in Georg, and they're all perfectly willing to have sex with him. The ending finds all four of them in bed together.
- The play and film Design for Living revolves around the three-way relationship between two (male) best friends who are both in love with the same woman. They try this, but jealousy breaks them up and the woman marries someone else until she decides that she still loves her boys, and as they want her back, the three of them decide to give it another try.
- In Dodes'ka-den, two of the wives in the neighborhood amuse themselves by swapping husbands from time to time. The drunken husbands barely notice.
- DodgeBall: A True Underdog Story throws in a love triangle in the last 2 minutes—and promptly goes with this solution.
- In the 1999 TV movie Journey to the Center of the Earth, after arriving to the land beneath the crust, the adventurers encounter a village of humans. Their guide McNiff immediately takes a liking to the local women, who respond to the big man from above. He then sees men glaring at him and finds our they're the women's husbands. Apparently, they practice polygamy. He grins and takes two women to a shack to exchange cultural knowledge. The idea of limiting relationships to only two people seems ridiculous to the locals, one woman asking in disbelief if women from above really like monogamy.
- A Home at the End of the World has the main characters decide to form a family, only for it to eventually break down.
- Jules and Jim focuses on a three-way pairing, with an eye to determining whether it can possibly last. In and of itself, polyamory is deemed acceptable, but "pioneers must be humble and unselfish," and jealousy results in a Murder-Suicide.
- The Dutch movie Liever Verliefd ("Preferably In Love") has the main character marrying both of her love interests at the end.
- Mediterraneo: Two brothers, Italian soldiers in World War II manning a lookout post on a remote island, meet a sexy shepherdess. They spend the rest of the war having Three-Way Sex with her. Their commanding officer is puzzled when they volunteer for permanent duty on the mountaintop lookout post.
- Professor Marston and the Wonder Women explores the relationship between William Moulton Marston, Elizabeth Marston, and Olive Byrne, and its effect on the creation of the lie detector (which the Marstons invented) and Wonder Woman (which Mr. Marston created and wrote under the pseudonym William Moulton). See Real Life, below.
- A woman and two men try this in Paint Your Wagon. It sort of works for a while; one of the men eventually departs, not so much because of the triangle, but because the area's becoming too civilized for his taste.
- Sappho: Sappho clearly wants Phil and Helene to have a trio with her. She encourages them to get involved. However, while they have sex, both reject this in the end.
- In Scott Pilgrim vs. The World, Wallace Wells, Scott's gay roomate sleeps with Stacey Pilgrim's boyfriend Jimmy and another nameless guy later on. His boyfriend, "Other Scott" does not seem to mind as at one point they're all seen sleeping in the same bed together, as well as Scott.
- Ramona Flowers also dated both Katayanagi Twins at the same time.
- She's Gotta Have It revolves around the polyamorous life of the protagonist and its acceptance or not by people around her.
- Sweetwater: Josiah is a polygamist who has two wives, while still pretending he's only married to one.
- In Vicky Cristina Barcelona, Juan's ex-girlfriend shows up after Cristina is already living with him. Things go from awkward, to tense, to sexy, back to tense, to falling apart entirely.
- Strongly implied at the end of Viridiana. After Letting Her Hair Down, Viridiana, who is obviously very changed by her experiences, enters the bedroom and finds Jorge and his lover Ramona. She sits down at a table with them. Jorge, who has a deck of cards, starts dealing, looks at Viridiana, and says "When I first saw you, I knew that we would end up playing cards."
- Another one from Woody Allen. When Melodie's disapproving mother Marietta shows up in Whatever Works, she goes on to date two men that agree to share her.
- Brazilian erotic western comedy Um Pistoleiro Chamado Papaco has Linda, a woman with four husbands, all of which the gunslinging protagonist kills on a Showdown at High Noon.
- Subverted in American Horror Story: Asylum with Kit, Alma and Grace. They set up housekeeping together but it does not end well, especially for Grace.
- Londo Mollari on Babylon 5 has three wives and a mistress, but it's kind of an aversion since he would gladly toss the polyamory and his three wives out the window, and marry just the mistress he truly loves (his marriages were political). He sums it up rather bluntly:
Londo: Here. Look. These are my three wives: Pestilence, Famine, and Death. Do you think I married them for their personalities? Their personalities could shatter entire planets! Arranged marriages. Every one. But they worked out, they inspired me! Knowing that they were waiting at home for me is what keeps me here—75 light-years away!
- Big Love, being based around Fundamentalist Mormon polygyny, is both an example and a counterexample to this trope, especially since it's depicted that women are often wed as young teens, ergo matches are made outside of the realm of informed adult consent. However, the family of the main characters mostly came together as consenting adults, though Margene revealed in season 5 that she was only 16 when she married Bill. The age of consent in Utah is 18.
- In Black Sails:
- Captain Flint's back story shows that he was in a polyamorous relationship with both Miranda and Thomas Barlow back in England. Thomas' rumored death is what drove Flint and Miranda to Nassau and began Flint's days of piracy.
- Anne Bonny, Jack Rackham, and Max have a threeway relationship beginning in Season 2.
- In Cable Girls, Carlota, Sara and Miguel are a trio.
- In an episode of Boston Legal, two women come to Denise and ask her to defend their husband. He married each of them in a different state, and the three now live together and have children. They seem to be a sincerely happy family; one wife and the husband work, while the other wife stays home and takes care of the house and kids. Their children are well-adjusted and the spouses are all mutually affectionate and supportive. Unfortunately, someone found out and reported him for polygamy. The women argue that, while they did break the law, the law itself ought to be struck down; after all, it's a consensual relationship between three adults, and they're not hurting anyone. Denise agrees, but unfortunately loses; whether the law is fair or not, it's still the law. The DA agrees to drop the charges when the husband offers to divorce his wives, a situation none are really happy with, but it beats their children's father being in jail.
- Sister Clarice Willow on Caprica is married to multiple men and women, who are all married to each other. This is implied to be unusual but perfectly legal.
- Columbo: In episode "Murder, a Self-Portrait", killer-of-the-week Max lives with and is in a polyamorous relationship with his ex-wife Louise, his current wife Vanessa, and his girlfriend Julie. He kills Louise when she tries to leave him, although that is more because she knows a dark secret from his past.
- Doctor Who has invoked this on a few occasions:
- In "The Husbands of River Song" it's revealed that River Song became married to at least two other individuals (albeit one for the sake of a mission) while still considering herself to be married to the Doctor. The Doctor does not appear to be disturbed by this at all.
- The Doctor unambigiously falls in love with Clara Oswald over the course of her time on the show, leading to an Act of True Love scenario covering billions of years leading to an Anchored Ship at the end of Series 9. In the very next episode (the aforementioned "Husbands of River Song"), we learn this all happened while he was still married to River Song. Due to the Doctor having undergone a self-inflicted Mind Rape that caused him to lose the memory of being in love with Clara, however, it is unclear whether River is ever made aware of his relationship for Clara.
- Given the Timey-Wimey Ball nature of the show, it's difficult to say when, exactly, the Doctor was married to any of his wives (which include but are not limited to River Song, Queen Elizabeth, and Marilyn Monroe). And, of course, that doesn't cover any of the relationships he had which didn't result in marriage. Considering that he often crosses paths with his various love interests out of order, he could be said to be in all the relationships at the same time.
- Clara isn't immune to this either, as she attempts to balance relationships with both the Doctor and Danny Pink in Series 8, and in Series 9 while (per Word of God) enamoured with the Doctor, at some point she also enters into an off-screen love affair of some sort with Jane Austen. Clara's polyamoric tendencies are another ingredient in her becoming a Distaff Counterpart to the Doctor.
- The ability to be polyamorous is considered a defining character trait of Series 1 companion Captain Jack Harkness, who is shown as equally attracted to Rose Tyler and the Ninth Doctor. Although the series never follows this very far, when it is referenced neither Rose nor the Doctor appear too disturbed by it.
- In the Elementary episode "All My Exes Live in Essex" Holmes and Watson must solve the murder of a woman who was simultaneously married to two different men. And was also in an earlier 6-way group marriage with three other women and two men, before that one.
- The Following: The rather twisted Emma/Jacob/Paul Love Triangle seemingly resolves as this in episode 4.
- Phoebe finds out at the end of the third season that the mother who raised her isn't her biological mother; when she meets her bio mom in Montauk, she tells Phoebe that herself and her parents were "kind of a couple" together.
- In an early arc Chandler is in a relationship with a woman who's married and has another boyfriend. He's initially on board with the idea of just being together for the sex but quickly realises he wants more of a relationship. They break up after he learns she's started seeing a fourth guy.
- In another episode, Joey finds out that his father has a mistress. As it turns out, his mother already knew and is fine with it.
- In Gotham, mafia bosses Barbara Kean, Butch Gilzean, and Tabitha Galavan have become this as of mid-late season 3, with Tabitha being the center of the relationship. Although there are no Love Triangle strains between them, Barbara and Tabitha's personal politics combined with Barbara's thirst for power are putting a strain on their side of the relationship by the end of the season.
- Frank and Claire Underwood from House of Cards (US) are polyamorous and accepting of each other's partners as long as they can keep their relationships discreet and out of the public eye. This also applies to their bodyguard Edward Meechum, who is in love with and undyingly loyal to both Claire and Frank. The feeling is mutual. In season 4, Claire is worried that she'll have a difficult time keeping her relationship with Tom Yates hidden and feels that the timing of their relationship, so close to the failed assassination attempt on Frank's life, is problematic, so she resolves to break up with Tom. Frank on the other hand believes that Tom is good for Claire and that she really loves him. He essentially vetoes her decision which leads to a heartwarming pep talk that reveals his views on polyamory and his long-standing relationship with Claire:
Frank: He should stay on, because he can give you things that I can't. Look, Claire, we've been a great team. But one person—one person cannot give everything to another person. I can't travel with you. I don't keep you warm at night. I don't see you the way he sees you. It's not my permission to give, but you'll do what's right for you. But I want you to know, if you wanted, I know you'll be careful. And I'll be fine. I mean, if we're gonna go beyond marriage, let's go beyond it.

One day, he enters her place to find her in bed with two guys (all still clothed, for PG reasons), who she calmly explains are her husbands. Furthermore, she invites him to join them. He refuses and later finds out that his friends knew that polygamy is legal and perfectly acceptable in this world.
- Star Trek:
- Dr. Phlox of Star Trek: Enterprise comes from a poly civilization. He has three wives, each of whom has three husbands, who themselves have three wives each. In a way you can say that all the Denobulan are part of one giant marriage group. There's also indication that three ISN'T the limit, since Feezal, who already had three husbands, attempted to seduce Trip. Phlox felt that Trip should have gone for it, indicating that Denobulans also lack any concerns about marital fidelity.

- The Patrick Fiori song "4 mots sur un piano"—it's the prettiest song about a triad you'll ever hear.
Vous étiez ma vie comme la nuit et le jour
Vous deux, nouez, filiez mon parfait amour
Un matin vous mavez condamnée à choisir
Je ne vous aimais qu'à deux
Je vous laisse, adieu
Choisir serait nous trahir
- "I just can't see you and me and her without each other "

make me feel the same
I want you and I want him.

Of all the ways I've ever dated
It's never been so complicated
The chain can extend to eternity
'Cause my boyfriend's girlfriend isn't me
- "Millionaire Girlfriend" by Jonathan Coulton seems to suggest this, since it will be "my beloved and my millionaire girlfriend and I", until the last verse where it's revealed that he's just working to get power of attorney over all her assets.
- The David Crosby song "Triad", most famously recorded by Jefferson Airplane. Notably, contains multiple Shout Outs to Stranger in a Strange Land.
You both stand there
Your long hair flowin'
Your mind still growin'
Sayin' to me:
"What can we do now that we both love you?"
I love you too
I don't really see
Why can't we go on as three?
- Olivia Newton-John has the song "Culture Shock" where the (female) POV desires a three person relationship:

How can you love two people at the same time? Ooh ooh
Now I don't want to lose you, but I can't give him up
- Unknown Mortal Orchestra's concept album "Multi-Love" explores the relationship triad consisting of the singer, his wife, and another woman.
- "Can't Help But Fly (The Poly Song)" by Climbing Poetrees
- The Gaymous song "Let's Pretend We Don't Have Feelings" has a line implying this about the singer and the person they're flirting with (which makes sense considering the song's lengthy references to queer culture)
But that don't mean that I am your primary boo
- The Mechanisms' album High Noon Over Camelot is an adaptation of the Arthurian Legend. Among other such changes, Arthur, Lancelot, and Guienevere are now a mutually loving and faithful triad.
Lancelot: Guinevere, you're my stars. Arthur, you're my night.
- In A Gentleman's Guide to Love and Murder, Monty Navarro begins an affair with his childhood crush, Sibella Hallward, and later marries his distant cousin, Phoebe D'Ysquith. Upon his imprisonment, Phoebe questions Monty on the nature of his relationship with Sibella, after which the two women conspire to get Monty out of his murder charge and the two make an agreement to share him.
- The Noël Coward play Design for Living explores every possible combination of playwright Leo, artist Otto, and decorator Gilda before finally having them inform her husband Ernest that his services are no longer required, as the three of them intend to live in what Ernest decries as a "disgusting three-sided erotic hodgepodge."
- In Gilbert and Sullivan's Trial by Jury, someone proposes that the defendant (in a Breach of Promise of Marriage suit) "marry this lady today, and marry the other tomorrow".

- Cabaret has a song about it: "Two Ladies".
We switch partners daily
To play as we please
Twosies beats onesies,
But nothing beats threes!
- Ace Attorney: Angel Starr references having multiple boyfriends, even telling the judge that there's a slot open for him.
- In Cultist Simulator, two of the romanceable cultists, Victor and Rose, are already in a relationship with one another, and won't break it off if they start dating the player. Even so, they all come to an understanding that suit everyone.
- You can suggest this as a solution to a Love Triangle in Dragon Age: Origins but the more prudish Love Interest rejects the idea and breaks off the relationship. But there are fan mods that let you have a relationship with more than one Love Interest, and one of them is outright called Polyamory. If you then marry Alistair to Anora and make him sleep with Morrigan or marry her yourself, the love polygon gets rather complicated.
- Dragon Quest VIII: Morrie, owner of the Monster Arena, is quite clearly in relationships with all four of the bunny girls working there. That lucky son of a bitch!
- In the final route of Duel Savior Destiny (And also the original Justice, though much more blatantly) this seems to be the final solution to the romance. Crea takes center stage, though.
- The Elder Scrolls:
- Dibella, the Aedric Divine Goddess of Beauty who is also associated with the carnal and sexual aspects of love, holds no limit on the number of lovers one may have. Instead, she demands focus on the quality of the essence of love, not the quantity.
- Mara, the Aedric Divine Goddess of Love, is associated with the familial, matrimonial, and fertility aspects of love. Despite this, depending on the religious tradition in question, she is coupled with several other gods. She's sometimes depicted as one of Shor's wives, along with Kyne. The old Nord tradition also makes references to her being the handmaiden of Kyne, concubine of Shor. Other traditions have her variously the wife of Akatosh, Lorkhan, or both. Sometimes the concubine of both. Yokudan tradition has her, as Morwha, as the wife of Ruptga. However, she has four arms so that she can "grab more husbands".
- In Fallout 4, you can romance multiple companions if you choose to, since Word of God is that they don't sweat that sort of stuff in the post-apocalyptic wasteland. The catch is that if any previously-romanced companion is around when you flirt with someone else, you'll lose approval points with them, though not enough to jeopardize an existing relationship in itself. And if you've dismissed her to flirt behind her back, Piper Wright uniquely has a scene where you can find her talking with detective Nick Valentine about investigating your infidelity, though this has no effect on your relationship with her. Interestingly, if you're in a relationship with both Piper and Cait, swapping one out for the other results in unique, flirtatious dialog that suggests that the two of them might also hook up. No other romanceable companions act this way.
- Ryudo, Elena and Millenia, from Grandia II, though Elena and Millenia were, for most of the game, technically the same person.
- Hades allows Zagreus to pursue all of the game's romance options at the same time with no penalty. Not all that unusual for a Greek god, after all. If you intiate a relationship with Thanatos while already dating Megaera, he explains that they've spoken about it and not only is she okay with Zagreus being with them both, she was the one who talked Thanatos into acting on his own feelings.
- Jade Empire, allows you to do this if you keep insisting to Dawn Star and Silk Fox that you can't choose just one of them, to the point that if you do make a choice at the very last time they ask you to decide as opposed to maintaining your indecision, both will break it off with you, not wanting to hurt the other's feelings. After the game, though, you end up with only Silk Fox, Dawn Star going off to do her own thing. To make things even more amusing, at some point before the final decision, you might also find out that they're cousins.
- Lonely Wolf Treat: In Dreaming Treat, you can chose to have Treat take a bath with both Mochi and Moxie during an Erotic Dream.
- Mass Effect: You can suggest this as a solution to a Love Triangle, but the more prudish Love Interest rejects the idea and breaks off the relationship.
- Male player characters in Neverwinter Nights: Hordes of the Underdark can suggest that Aribeth and Nathyrra share him. It actually works.
- Overlord II where you collect three mistresses over the course of the game, are allowed to keep them, and chose any one to be your primary one at any point in the game. It's possible to get all of them to "get along" with and without innuendo.
- Pathfinder: Kingmaker:
- Octavia and Regongar are a bisexual couple with a great deal of trust in each other; romancing both at the same time is practically encouraged and even if you only express interest in one, the other doesn't mind sharing.
- Kalikke and Kanerah can be persuaded into this during the end-game if the player character expresses interest in both of them and they remain friendly with each other. As Kalikke is a Shrinking Violet, she practically has to be pushed into revealing her interest in the player character by Kanerah either way.
- Phantasmagoria 2 has bisexual hero Curtis wishing he could run off and live with his girlfriend Jocilyn and his doomed gay coworker Trevor, both of whom are in love with him. At one point Curtis was dating both Jocilyn and his BSDM loving coworker Therese, but only Therese was okay with the idea of their having an open relationship.
- Quest for Glory V: A glitch lets you propose to three love interests and no one objects. Though only one appears as the Hero's consort at the end.
- You can try it in Star Wars: The Old Republic, particularly with a male Sith Warrior that's corrupted and romancing Jaesa, but is still nice to Vette; Jaesa is open-minded on the idea of sharing, but Vette is squicked out. None of the other potential love interests will go for it. Though any romance option with the Imperial Agent and Vector is going to be a crowd scene since he's tied to a Kilik hive.
- Xenoblade Chronicles 2: Rex is in love with both Pyra and Mythra. While this is complicated by the fact that they are technically the same person, he treats them as different people and loves them both equally (and they love him back). At the end of the game, they are revived in two separate bodies, edging it towards a slightly more normal example. On the title screen after beating the game, Rex stands on a plain holding hands with Pyra and Mythra. After beating New Game+, Nia (who is also in love with Rex) jumps into the picture. She either holds hands with Rex and Pyra, or pushes him out of the way and takes the hands of both the other girls.
- World of Warcraft: Alexstraza, though widowed many times over, used to have several husband-equivalents at once.
- Cross Days: You can do this in another very hard to get ending with Makoto, Yuuki, and Kotonoha. Makoto describes it as Kotonoha being the girl he loves most and Yuuki being the boy he loves most. Except Kotonoha doesn't know the all important details. She is seemingly okay knowing she is not Makoto's only lover, happy enough knowing she is girl he loves most, but she wasn't told that "other woman" is actually a boy, and that Makoto loves him equally to her, in a perfect example of From a Certain Point of View. And if she ever found out she could possibly murder Yuuki with some form of deadly weapon as she does in other ending where she overhears them having sex, and while Makoto is planning on trying to get her some mental help, this is the best solution he can come up with in the meantime.
- In Long Live the Queen, this is one of the possible ways Elodie can pursue a romance with Brin. If Elodie has the opportunity to choose her fiance at the end of the game, Brin will suggest that she marry her brother Banion so that Elodie and Brin can spend more time together as sisters-in-law; Elodie ends up being close to both of them. And if Brin and Joslyn aren't already entangled with other matters, Brin will even marry him to doubly ensure a connection to Elodie as her stepmother. Elodie is much closer to Brin than to Banion in this scenario, though, but their respective husbands still seem happy with this arrangement. Depending on what else happens to all involved characters, there are further variations of whose kids are being raised by whom. Including the Banion+Elodie and Brin+Joslyn children all being raised together, making them pseudo-siblings on top of everything else.
- Monster Prom: It's heavily implied that, while not in a relationship like that, the player character is polyamorous and actually wouldn't mind to date all of the Love Interest characters. The achievement for getting all characters to prom is actually called "Polyamorous". There are some moments that the player character will also voice wanting to date more than one person, including stating to dream about both Polly and Damien, as well as going on a triple date with Damien and Miranda (during the "Dragon Heat" events). Even the Golden Ending goes along with this as it's about getting all of the main characters together for an orgy. The CG is of all of them waiting for you to join them in a hot tub.
- The "You Do You" Valentine's Day update in 2020 adds a route focusing on this kind of relationship, featuring the Interdimensional Prince and Dmitri.
- In Nekojishi this is the canon outcome. To the outside world Liao is dating Yan Shu-chi, but as seen in the DLC all three cats come to more-or-less share Liao.
- Rose Guns Days features what seems to be this between mafia boss Caleb, his underling Miguel and his mistress Amanda. While Miguel and Amanda quite clearly hate each other, the latter is in an official relationship with Caleb and the former has a lot of Ho Yay moments with him (which remain mere subtext in the VN but are more explictly romantic in the manga). Caleb, on the other hand, shows affection for both.
- One of the (very hard to get) endings in School Days has Sekai and Kotonoha do this to the protagonist Itou Makoto.
- The English Dating Sim Summer Session features a three-person relationship as one of the canon endings; indeed it's impossible to get that particular girl without sharing her with your roommate. It's unclear whether the two male characters are actually involved with each other or just sharing the girl in a V.
- In Amber's Magic Shop, a hybrid of Visual Novel and Time Management Game by Winter Wolves, there are two different kinds of polyamorous endings possible. In one the PC (the titular Amber) can be in a polygamous marriage with a man and a woman at the same time and in another she can be the girlfriend of a married woman with the full permission of the husband (but not being in a romantic relationship with him).
- In We Know the Devil, after each ending sees two of the kids hook up at the cost of the "third wheel" being pushed out of the friend group and possessed by the devil, the Golden Ending features Venus, Jupiter, and Neptune coming together after refusing to choose a scapegoat. Not only are all three girls together romantically, but all of them accept the Devil and reject God, bringing about "a new apple."
- In Heaven Will Be Mine, the Non-Linear Sequel to We Know The Devil, every ending sees all three of the protagonists end up together.
- The Flash Forward strips in the Space Arc of Arthur, King of Time and Space suggest that the Arthur/Guenevere/Lancelot triangle resolves this way in at least one timeline. Other strips hint that Arthur is well aware of the affair between his wife and his best friend in at least some of the other timelines, as well, but studiously ignores it.
- Cats N' Cameras: Main characters, Jim, Josephine and Sari are in what appears to be casual threesome. Jim and Jo are an established couple. Sari seems to be Friends with Benefits to both of them.
- Fans! has Rikk, Alisin and Rumy become a triple. This arc continued with the marriage surviving some storms to the point where thanks to alien medtech Alisin is currently carrying a baby Rumy and Rikk conceived.
- Sirkka in FreakAngels, who lives with a harem.
- Girl Genius: The Heterodyne Castle seems to prefer this as the ultimate solution for the Love Triangle between Agatha, Gil, and Tarvek. Comments by the Castle indicate that this was likely a common practice for previous Heterodynes, and plenty of other characters have suggested it too. The Ho Yay/Foe Yay between Gil and Tarvek doesn't really do much to rule out such a solution.
Violetta: Say—you wanna make a bet on who she'll pick?
von Zinzer: Sure! But, hey—she's the Heterodyne. Maybe she'll just keep 'em both.
- It's teased in some non-canon spin-offs, too.
Phil: Who thought haveing two boyfriends was a good idea?!
[cue Cheshire Cat Grins from Agatha, Zeetha and Kaja]
- It's teased in some non-canon spin-offs, too.
- Homestuck: The trolls have a romance system that's quite different from ours. They have four kinds of romantic relationships or "quadrants", only one of which corresponds to human romance norms. The ideal for a troll is to have one partner in each quadrant. As you can imagine, this makes for some very complicated situations.
- The Homestuck Epilogues: in the "Candy" epilogue, both Jane and Jade attempt a polyamorous relationship. Jane with Jake and Gamzee, Jade with Dave and Karkat. Neither of these end well for anyone involved.
- The Insecticomics has a lot of this, usually in the form of open relationships.
- The short-lived webcomic Jake the Rake.
- Kimchi Cuddles has become about philosophizing, but the earlier parts of the comics are about a group of poly friends.
- Karin-dou 4koma: Ran/Shizuki/Tamaryu, as per Ran and Shizuki's decision to resolve their rivalry over Tamaryu by having Shizuki be Tamaryu's wife, Tamaryu be Ran's wife, and Ran be Shizuki's wife. Ran explicitly says that the three of them are together a monogamous couple. Although Tamaryu isn't happy about the romantic aspect, they do get along quite well. When Eldelita attends a sleepover with them, she feels as awkward as someone invited to play and stay overnight at a newlywed's house.
- Maxine in Leftover Soup is part of a five-way. When a second woman entered the relationship she even forcefully reprogrammed her brain into bisexuality just so that she wouldn't be missing out on anything.
- Niels: The titular mob boss is in a relationship with a married couple, Duncan and Natalie, whose son Elliot sees Niels as a second father. They live together happily — Elliot's horror at once walking in on a three-way Primal Scene notwithstanding.
- Poly In Pictures depicts moments in the life of polyamorous, queer and neuroatypical people.
- Angela of Punch an' Pie believes in polyamory, but all this does is turn her into a Clingy Jealous Girl who is paranoid that her girlfriend is cheating on her with literally everyone she knows.
- Mentioned in Queen of Wands.
- Evidently a fairly common situation in the absurdly complex social circles at the university in Questionable Content.
- Sister Claire has two prominent poly relationships: Maman/Michele/Sylvia (with Maman the latercomer) and Hana/Hawk/Lark/Pidge (with Hana coming in much later).
- In Strangetown, Here We Come, the main trio eventually end up like this with Ripp and Johnny both going out with Ophelia, and before the fic died it was implied that Johnny and Ripp might start going out as well—Ripp was canonically interested, and Johnny at least had a whole lot of Ho Yay on his side.
- In Always Human, Sunati's parents Nisa and Prav are a Happily Married couple who also have a boyfriend, Vish.
- In The Accidental Space Spy, Datima males have more than one wife.
- While there are a few genuine relationships between the members of the main cast of Ennui GO! (Noah and Len, Hashim and Sarah, for instance), everyone that lives with Izzy has sex with everyone on a fairly regular basis. The twists are that Darcy is a lesbian and focuses on Izzy and Tanya (the cast page specifically describes their relationship as poly), and the men usually only have sex with the women, although Hashim and Hiro had sex once on a whim.
- In Rascals, the current dating situation with Quick, Raven, Chrissy, and Jazmin.
- Part of a side plot in Go Get a Roomie!: Allan, Evelyne and Steve are in a polyamorous relationship. Only Allan and Evelyne are engaged though, and in the beginning Evelyne makes it very clear that she doesn't have feelings for Steve and that Allan belongs to her while Steve is merely tolerated as a sex partner. Their relationship develops as the comic progresses, and when Evelyne gets pregnant and Steve tries to remove himself from the relationship altogether, she and Allen stop him, accepting him as an equal member of their partnership.
- Very common in Chakona Space
- The titular Chakats having a certain saying, "love doesn't divide, it multiplies."
- In addition, Foxtaurs are polygynous due to a 3:1 ratio of vixens to todds and todds are "obligated" to make themselves available for stud duty once every five years.
- Caitians (aliens based on lions) are even worse, with an 8:1 ratio. Each harem usually consists of up to six women.
- Stellar Foxtaurs, having been designed with the best traits of Chakats and Foxtaurs, tend to have similar views towards casual sex. Though mating habits vary with some breeds, Polars don't form permanent relationships while Deserts tend towards triads, and Starwalkers mate as a large group but carefully control breeding.
- On the Dream SMP, Quackity, Karl and Sapnap are engaged to each other in a polyamorous relationship. Eret used to be engaged to Karl and Quackity, but that relationship didn't end up working out.

- Parodied by Hardly Working in "My Two True Loves", in which Pat sings about his dream to have this sort of relationship.
Pat: It'll be just you and me! and her!
- The Jenkinsverse has a triad relationship forming between Allison Buehler, Julian Etsicitty, and Xiù Chang as of Deathworlders Chapter 24.
- Metamor City has the Psi Collective members live in families/cells, with (preferably) one male and several females. This is because they believe that a war with the "mundies" (unpowered humans) is inevitable and that they'll need to prepare by breeding as many psychics as possible, but there aren't many powerful males. At the end of Making the Cut they even considered Gender Flipping "surplus" males.
- The Polyamory Bear, a parody of a Purity Bear video.
- Mackenzie in Tales of MU falls into this situation pretty quickly. As things stand, she is the lover of Ian, Steff, and Amaranth, the former two also being Amaranth's lovers (but not with each other as well).
- Bladedancer, Gateway, and Chain Lightning have this in the Whateley Universe.
- In LA By Night, main character Annabelle has both a boyfriend named Mark and a girlfriend named Ellenore. (It's unclear whether they're also involved with each other, though they are at least shown to be good friends.)
- Bojack Horseman: Hollyhock was adopted by eight gay men in a polyamorous relationship, explaining her Overly Long Name.
- In the movie "The Beast With a Billion Backs", Fry briefly dates a girl named Colleen who is living with her four other boyfriends. The main plot is centered around Yivo, a massive, hermaphroditous alien who starts a relationship with every organic being in the universe. At the end of the movie, both relationships end, as Colleen goes back to Yivo's universe with shkler, closing the portal between the universes behind them, and the movie ends with the Aesop that "love doesn't share itself with the world".
- Old Man Waterfall states that he loves his seven wives, and his husband.
- In "Future Stock", Fry refers to traditional families like "the lesbian coven across the street".
- Steven Universe:
- While the title character's parents loved each other, it becomes apparent Rose had a much longer-term relationship with Pearl that didn't stop when she hooked up with Greg. "Mr. Greg" states that Rose loved them both and saw no reason to choose, and she'd even had several lovers simultaneous with Pearl over the course of history. However, Rose had a rather naive view of love, and wasn't really considering Pearl's feelings. She thought Rose's other lovers were simply ignorable, and when Greg got into a deeper relationship with her, Pearl still felt that she was "losing" Rose to him.
Greg: Well, you know Rose.
Greg and Pearl: She always did what she wanted.
- A Gem known as Fluorite is a fusion who consists of six gems. Her dialogue implies ("if we find the right Gem") that the relationship between all of the Gems that make her is romantic. Unlike with Rose, Pearl, and Greg, there's no sign of any resentment between them, and Fluorite even mentions a willingness to add another Gem if they are compatible.
- While the title character's parents loved each other, it becomes apparent Rose had a much longer-term relationship with Pearl that didn't stop when she hooked up with Greg. "Mr. Greg" states that Rose loved them both and saw no reason to choose, and she'd even had several lovers simultaneous with Pearl over the course of history. However, Rose had a rather naive view of love, and wasn't really considering Pearl's feelings. She thought Rose's other lovers were simply ignorable, and when Greg got into a deeper relationship with her, Pearl still felt that she was "losing" Rose to him.
- In a truly bizarre example, the My Little Pony: Friendship Is Magic episode "Hard to Say Anything" has Sweetie Belle pairing up Feather Bangs, who had just lost to Big Mac in a contest to win somepony's love, with the three fangirls who had been following him throughout the episode. It's not even a matter of "Pick one," she just encourages him to go with all three of them, and nopony acknowledges this as being out of the ordinary. Perhaps it's just another example of real-life horse behaviour leaking into pony society.
- She-Ra and the Princesses of Power: Show creator Noelle Stevenson confirmed after the series finale that former Horde cadets Kyle, Rogelio and Lonnie are in this kind of relationship on her Twitter account.
- The Simpsons: In "Holidays of Future Passed", it's shown that Lisa had two girlfriends in college.

- Thai antiques dealer Thao Wichai married the identical twin girls-next-door from his childhood hometown.
- Misha Collins (Castiel on Supernatural) had a threesome relationship with his wife and another woman for some time, as explained in her book. She describes how a night of cosmos with a friend led to them all in bed together, which led to her later realizing that she had fallen in love with her friend, while still remaining in love with her husband, and that both of them loved each other and her. It all worked out in the end.

- In September 2012, three people were married to each other in Brazil.
- As stated elsewhere on the wiki, it has been reported by the news-magazine The Independent, "polygamy is a right enshrined in South Africa's constitution." South African leader Jacob Zuma is a prominent example. In 2010, he married his fifth wife in a traditional ceremony at his remote homestead. In terms of history, the news-magazine also stated, "In 1998, the University of Wisconsin surveyed more than a thousand societies. Of these just 186 were monogamous. Some 453 had occasional polygyny and in 588 more it was quite common. Just four featured polyandry. Some anthropologists believe that polygamy has been the norm through human history. In 2003, New Scientist magazine suggested that, until 10,000 years ago, most children had been sired by comparatively few men. Variations in DNA, it said, showed that the distribution of X chromosomes suggested that a few men seem to have had greater input into the gene pool than the rest.

Travis himself mentioned that Joe made a lousy husband, who really only wanted him superficially, and whenever he did try to connect with him, he would blow him off. Eventually, John left Joe after he ran off with a zoo employee, and Travis' story ended tragically after he shot himself with a gun.
