* SexChangesEverything: Invoked three times in ''VisualNovel/DaughterForDessert'':

* A GettingCrapPastTheRadar PG version happens in ''VideoGame/TalesOfXillia2''. The spirit [[TheTease Muzet]] talks about her experiences with [[IntimateHealing direct tethering]], which involves a human [[DoesThisRemindYouOfAnything filing a spirit with their mana]]. When the usually [[TheStoic stoic]] [[TheComicallySerious Gaius]] realises the implications of what he's done with her, he is absolutely ''mortified'' and starts rambling to himself about how he has to take responsibility.

For some reason, happiness does not appear to be coming with the coupliness. Blame the RuleOfDrama. Traits they formerly laughed off about each other are suddenly causing long bickering sessions that can result in one party storming off while the other stands there and cries; stuff they used to enjoy together has become boring and immature, since they're a couple now and should do more couple-oriented things (this view is often posited by female characters, and usually leads to more bickering).

* In ''Series/DoctorWho'''s "The Lodger," after the Doctor gets Craig and Sophie to admit their feelings for one another, they decide to "totally ruin their friendship." In the sequel episode the following year, they have a little boy named Alfie, or as he likes to call himself "Stormageddon, Dark Lord of All."

This is a specific subtrope of the ResetButton, and the "loss of love when sex enters the picture" version of RomanceAndSexualitySeparation.

* In the fourth ''Literature/TheSisterhoodOfTheTravelingPants'', this happens between Tibby and Brian. They had become a couple at the end of the previous summer, but didn't have sex until the beginning of the next summer. After a mishap with a condom, Tibby believes she may be pregnant and promptly freaks out. They don't fight so much as she refuses to talk to him.

** And possibly because of the sheer frustration of Ross and Rachel's relationship when Monica and Chandler had sex, none of this happened. When they argued it was mostly about legitimate couples stuff and they resolved it more often than not by listening to each other and being mindful of the fact that they were different people who would occasionally differ on things. This was partly because they were extremely close prior hook-up but unlike Ross and Rachel weren't hiding hopes for 'more' and starry-eyed. Instead Monica and Chandler were well-aware of each other's faults but still best friends who openly admitted they loved each other. You sensed for them the step from platonic to romantic love was a natural one, as they had a stable basis for their relationship.

** Spike argues this InUniverse in Season 6. Buffy however continues to insist ItDoesntMeanAnything, a contributing factor to their DestructiveRomance.

[[folder: Video Games ]]

* After getting deflowered in the end of ''VideoGame/LeisureSuitLarry'' 7, Shamara undergoes a complete personality change at the beginning of LSL 8.

[[folder: Web Comics ]]

This is a specific subtrope of the ResetButton.

* In ''Film/{{Hellboy}},'' Liz and HB were friends who got along well in the first movie. In ''Film/HellboyIITheGoldenArmy'', they're at each others throats and arguing until Liz literally explodes.
** In her defense, [[spoiler:she finds out she's pregnant very early in the film, so her stress could be down to hormones and trying to deal with the fact.]]

* In ''VideoGame/MassEffect2'', Jack will offer you casual sex early on, but if you take her up on the offer, she will subsequently refuse to talk to you. If you choose to [[RomanceSidequest romance her]], no sex is involved at any point.

* A major part of ''WhenHarryMetSally''. Though they weren't fighting over petty things as much as rehashing things to figure out how they work as a couple. Still an example but not as petty as other versions.

-->-- '''[[TheProtagonist J.D.]]''', ''{{Scrubs}}''

* On ''{{Scrubs}}'', when J.D and Elliot hooked up the first time, the entire next episode (which was unusually long when originally aired, no less) was devoted to having them essentially tear each other apart until they called it quits.
* Ross and Rachel of ''{{Friends}}'': A. Ross and Rachel kiss. Everything'll be great now, right? Ross writes a list of Rachel and Julie, pros and cons. This infuriates Rachel, and she dumps him. B. Later on, they get together for real. The relationship lasts the better part of a year, but Ross gets jealous of Rachel's new job and her coworker Mark. Some misunderstandings and a sleepover with the hot copier girl, and they break up. C. Later on, Rachel says that she'll be with Ross again if he accepts full responsibility. He agrees not knowing what he was agreeing to. They break up again. D. They get drunk in Las Vegas and get married, then divorced. E. Rachel gets pregnant. Cue fighting about whether to get married or not. I've probably skipped a few steps in here, but you get the idea. The creators dangle the carrot in front of us and yank it away over and over again, knowing we'll fall for it every single time.

After a long battle with UnresolvedSexualTension, WillTheyOrWontThey, multiple [[MomentKiller moment killers]] and general [[ShipTease 'ship teasing]], it's finally time for two characters to settle into happy coupledom.

* Seems to have happened to Marten and Dora in ''QuestionableContent'', although not to the point of totally driving out affection. Mostly it just seems to have brought out Dora's [[GreenEyedMonster jealous streak]]. Everything else is as normal as it can be when everyone you hang with has [[DysfunctionJunction crippling neuroses]].

* In ''Series/BuffyTheVampireSlayer'', sleeping with Buffy triggers the loophole in Angel's curse and ''robs him of his soul,'' turning him from TheAtoner into a monster. As if the subtext wasn't obvious enough, Buffy uses the mundane version of this trope to explain away to her mother how she could have slept with someone now so evidently psychotic.
* Betty and Henry on ''UglyBetty'', resulting in ShippingBedDeath.
* In ''Series/StarTrekTheNextGeneration,'' Picard is sent back in time with a chance to alter a critical point in his life. Along the way, he winds up sleeping with someone who he'd previously only been friends with and finds he wound up destroying their relationship as a result.
