Sometimes a character really ''does'' want to [[JustFriends just be friends]] with another; at least as far as conscious decisions go, but the sexual attraction and sexual thoughts persist.

Maybe something about the friend, whether appearance or personality or whatever else, just seems sexy. Perhaps the character is just so dirty-minded by their very nature that they just have sexual thoughts anyway. Whatever the case, the lust conflicts with the friendship, no matter how hard they try to conceal the former.

Compare AND contrast with IDontWantToRuinOurFriendship. The difference lies in the reaction of the character feeling the romantic/sexual feelings (and, in many cases, the former relationship between the two): if they're creeped out by their sudden attraction to the person they had always considered a brother/sister, it's this trope; if they're worried that admitting their feelings to someone with whom they've been Just Friends will cause drama or change a group dynamic, it's IDontWantToRuinOurFriendship.

Compare StupidSexyFlanders, as it reflects on a similar conflict between the sexual thoughts one has and consciously thinking one shouldn't have such sexual thoughts. ([[CaptainObvious And yes, this is snowcloned from it]].) Compare and contrast FriendsWithBenefits, one solution to this problem if it's mutual.

TruthInTelevision, of course. After all, it's considered normal to lust after someone you don't know, as opposed to a close friend (that you ''do'' know).

!! Examples:

[[foldercontrol]]

[[folder: Anime and Manga ]]

* In {{Yuri}} series SasamekiKoto, Sumika Murasame [[YoureNotMyType is stuck being]] JustFriends with LipstickLesbian Ushio Kazama (not this trope), but as the story goes on, we find out that [[spoiler: Ushio has fallen for Sumika at some point but is extremely uncomfortable being attracted to a close friend]] (this trope).
* From ''{{Touch}}'': Tatsuya: ''"One day, we became aware that one of the three of us was a girl."'' Thus began the {{childhood friend romance}} {{love triangle}}. Oh, and a good deal of baseball too.
* In ''LightNovel/InfiniteStratos'', this is VIRTUALLY [[UnluckyEverydude Ichika]]'s relationship with all the members of his UnwantedHarem: he has shown some interest in all of them, ranging from cuteness (Rin, Laura, Char), to fascination of beauty (Cecilia, Houki on certain instances) all the way to outright sexual curiosity (Houki, probably Char). However, [[ChasteHero he has not decided to choose from among them]] [[DoomMagnet due to his circumstances.]] Unfortunately, [[ClingyJealousGirl the girls themselves]] seem to misinterpret his actions as [[CluelessChickMagnet that of being a very dense oaf.]]
** Hilariously, [[spoiler:[[TheAce Tatenashi]], [[EnsembleDarkhorse who has all the charm required of the trope]]]], [[EpicFail is disregarded as girlfriend material]] because [[MarySue "She's just too good"]].

[[folder: Fanfic]]

* While Carol and Harry are pretty firm about being JustFriends in ''Fanfic/ChildOfTheStorm'', there are persistent mild shippy undertones to their friendship, and it's implied that while Harry's fairly new to the whole sexual attraction thing (he's thirteen when the story starts), he wouldn't mind if they got a RelationshipUpgrade. As it is, however, he seems equally happy with being JustFriends, since Carol has about two actual guy friends who aren't trying to get in her pants and very few friends full stop.

[[folder: Film ]]

* Billy Crystal's character in ''WhenHarryMetSally'' epitomizes this trope, and it plays a major part in the plot of the film itself.

[[/folder]]

[[folder: Literature]]

* A lesbian example of the trope occurs in ''Killswitch'', the third book in the CassandraKresnov trilogy by Joel Shepherd. The titular android's bisexual best friend admits to having fallen in love with Cassandra, but the latter is straight and the friend doesn't want to affect their working and non-working relationships.
* This is part of the relationship between [[TheDresdenFiles Harry Dresden]] and [[TheEmpath Molly]] [[SheIsAllGrownUp Carpenter]]. He doesn't reciprocate her [[HotForTeacher feelings]] towards him (and feels it would be creepy to do so, given that he's known Molly since she was a child), but still finds her attractive. [[InnocentCohabitation Awkwardness]] [[TrueCompanions ensues]]. Something similar exists between Harry and Karrin Murphy, as they have been close colleagues since the first book and gradually getting closer in other ways, while both are aware that the complications of a relationship would be dangerous for both of them.
* At the beginning of ''Literature/DoraWilkSeries'', Dora tries to keep things friendly between her and Miron, but both have rather sexual thoughts of one another. The problem here is mostly that Dora, as a succubus expy, is used to people lusting after her because of her powers and thus thinks that her relationship wih Miron would be result of magic rather than actual attraction. [[spoiler:They do get together in book 3]].

[[folder: Live Action TV ]]

* ''Series/BuffyTheVampireSlayer'':
** This was pretty much how Xander felt about Buffy after he got past being outright attracted to her and too inept to say so.
** Willow finally gets together with Xander. When they're both with other people.
* On ''Series/{{NCIS Los Angeles}}'': It's a quick moment, but it's there. When Kensi is compelled to do a quick change in clothes in the middle of an undercover op, Callen's eyes widen. [[HeartwarmingMoment And he politely looks away.]]
* For a brief period Series/{{Angel}}'s feelings towards Cordelia are this, with him sort of horrified that he does feel something romantic for her when previously they were like family. By the time he gets over it there's other issues preventing them getting together... not that there [[CantHaveSexEver weren't already]].
* In ''Series/{{Community}}'', Jeff and Annie often fall into this territory. They're pretty much the OfficialCouple by this point, but the age difference and [[LikeBrotherAndSister nature of the relationship so far]] has made them both feel somewhat squicky about the idea of hooking up, despite how much they both seem to want to hook up.
* All three of the male roommates on ''NewGirl'' have had moments like this with their female roommate Jess. This is especially the case for Nick, who has some serious UnresolvedSexualTension with her.
* In ''Series/DoctorWho'', the Eleventh Doctor and Clara have problems with this towards each other, due to some minor UnresolvedSexualTension between both of them. (They both insist on only being friends, as much as they like each other.) The trope is more prominent on the Doctor's side and usually PlayedForLaughs, while Clara off-handedly mentions once (while alone) that she has to keep herself in check and not develop a crush on him. Later, though she's not attracted to the older-looking Twelfth Doctor, she still makes a cheeky compliment about [[GrandpaWhatMassiveHotnessYouHave his handsome looks and charismatic voice]], [[GrumpyBear much to his annoyance]].

[[folder: Visual Novels ]]

* In ''VisualNovel/LittleBusters'', if you choose to stay with the guys rather than go with the girls on their sleepover, they end up conversing about love and when Riki is evasive, Masato jokes that he has a crush on Kyousuke. If you choose to lie, Riki admits mentally that he does, but denies it because [[IDontWantToRuinOurFriendship he doesn't want to ruin their friendship.]] Then when he asks Kyousuke who he likes, Kyousuke replies 'right now, Riki is my number one', causing Riki to [[LuminescentBlush blush heavily]]. However, he berates himself for thinking that way, stating that indecent thoughts like that are desecrating their friendship. Immediately afterwards Kyousuke asks him [[ThatCameOutWrong 'Wanna do it?']] Referring, of course, to playing tabletop baseball.
-->'''Riki''': ''Uooooh, what a misunderstanding I just had!! It's a desecration of our friendship... God of friendship, forgive me...''
* In ''{{Morenatsu}}'', it's revealed that [[spoiler: Shin feels this way about you]], which makes his self-conscious issues even more frustrating for him.

[[folder: Web Comics ]]

* In ''Webcomic/AllNewIssues'', [[http://www.allnewissuescomic.com/comic/85-getting-closer/ Todd and Robyn look like they're almost going to kiss]], and then this trope kicks in.
* In ''Webcomic/{{Sunstone}}'', Anne reading Lisa's bibliography of [[InkSuitActor self-starring]] kinky erotica served as a good way to explore her interest in BDSM, but also, to Anne's annoyance, a good way to explore an interest in Lisa.

[[folder: Western Animation ]]

%%* Brian for Lois in ''WesternAnimation/FamilyGuy''.
* Linda to Francine in ''WesternAnimation/AmericanDad''. What makes this more tragic is Linda is unaware that Francine is bi and doesn't seem to consider lesbian affairs as cheating.
* ''WesternAnimation/StarVsTheForcesOfEvil'': Despite canonically having crushes on other people, both Star and Marco have each shown an awkward physical attraction to the other at some point.
