* ''Series/{{Atypical}}'': In the first season, Casey seemed to be straight-up heterosexual, having sex with her boyfriend Evan. However, come the second season she started to question her sexuality with a girl, Izzie, whom she meets at her new school Clayton Prep. By the third season, she is torn apart by her attraction to both of them, but [[spoiler:ultimately goes with Izzie over Evan--that isn't to say she didn't break down crying when she broke up with Evan]].

Stories which prominently feature a GenderBender will often give the affected a pair of opposite sex love interests. These tend to follow a logic akin to TransEqualsGay, strongly connecting a relationship with their former sex to [[SecondLawOfGenderBending identifying with their current one]]. Some combination IfItsYouItsOkay and JumpingTheGenderBarrier is typically involved. However, if a character is a casual SexShifter, such a mix of different loves [[ShapeshiftersDoItForAChange could be considered with much less conflict]].

* In ''Manga/AfterSchoolNightmare'', protagonist Mashiro was born {{intersex}} but identifies as male and is torn between the girly and androphobic Kureha and the cold and dominant Sou. This love triangle represents Mashiro's conflicting feelings about his gender - he is happy to date Kureha as it puts him in a masculine position, but is uncomfortable with his attraction to Sou because [[TransEqualsGay he worries that it's proof that he's 'really' a girl]]. (Somehow, the idea that he might just not be straight doesn't come up.)

* ''Series/KillingEve'' presents a [[PsychoticLoveTriangle psychotic]] version between Eve, an apparently straight married woman, who becomes obsessed with bisexual serial killer / assassin, Villanelle. Eve's husband, Niko, is completely disgusted by the violence that Villanelle brings into their lives, and Eve's growing attraction to it, meaning that Eve has to choose between Villanelle and homicidal chaos or Nico and boring normality.
* ''Series/LostGirl'': Bo, a succubus fae, not only has strong feelings for Dyson, a male werewolf Fae, but for Lauren, a female human scientist working with the fae. Initially, Bo tries to keep her distance from Lauren, as she hasn't figured out how to fully control her drain-life-via-sex powers, and "feeds" of Dyson fairly regularly because fae have more life to give, so she can feed without killing him. As the series progresses and Bo learns to control her powers more (and various characters' dark secrets start coming out), the situation develops into a full-blown love triangle, with jealousy, betrayals, suspicion, and angst.
* ''Series/TheMurders'': This turns out to be the root of the rivalry between rappers Lil Rex and DB Kane. Lil Rex was publicly dating Ayanna, but he also had feelings for DB Kane. However, as both men were still in closet fearing backlash to their careers, no one but the three of them knew. This worked for a while, until Lil Rex accidentally got Ayanna pregnant, and feeling he had to step up broke it off with Kane. Heart broken and humiliated, Kane started a feud with Lil Rex. Following Lil Rex having a breakdown, Kane and Ayanna agreed that he needed both of them, and finally came out with the truth, deciding to see how {{polyamory}} worked for them.

(Somehow, the idea that he might just not be straight doesn't come up.)

* ''WesternAnimation/StevenUniverse'': The [[WholeEpisodeFlashback flashback episodes]] focused around Greg as a young twenty-something dating Rose depict a constant conflict between Pearl and Greg over Rose's affection, where the former is a big ClingyJealousGirl who tries to chase Greg away so she can have Rose to herself. The narration implies a major reason why Rose went for Greg over Pearl is because Greg was the first person to treat Rose like they were on the same level, while Pearl put Rose on a pedestal and idolized her.
