So Bob's got a crush on Alice. We've seen him looking at her longingly, or heard him talk of her beauty but Alice isn't all that keen on Bob. He may have asked her out and been turned down before, or she may be in a relationship. They may be together, and Bob's ready to take it to the next level, but Alice's waiting for the right time.
This trope comes in when something changes. Now Alice wants sex with Bob and she wants it now! Maybe she's drunk, drugged, or under some other influence. Maybe she's broken up and on the rebound, or wants to make another guy jealous. Bob's dream has come true!
Only Bob knows that it wouldn't be right. He politely (and often insistently) declines her offer, pointing out that it would be wrong to take advantage of her like this. He tells her this while she's coming onto him and likely in a near-predator manner.
Bob will then feel bad for possibly hurting a girl's feelings and may get some mocking from people he tells. Occasionally Alice will thank him for being so noble and drop hints that he's an OK guy. Sometimes they get it together after this little talk.
This is almost always a guy refusing a girl because, on TV, men refusing sex is unthinkable. Also note that if the character had slept with the intoxicated person, it might be considered rape, depending on the level of intoxication.
Not to be confused with the American campaign of the same name, part of the US Government's "war on drugs".
This was adapted into the anime episode Ah! Please don't look at me like that! in the first season. He doesn't know what caused the change, but still refrains; you gotta respect that. Future events have revealed his ability to resist may have to do with the Ultimate Force suppressing his sexual drive.
In Ranma ½, Ryouga forcefully rejects a female Ranma's amorous advances after the latter was bewitched by a "Fishing Rod of Love." Ryouga, being Ranma's rival (and, often, enemy) is thoroughly freaked out by this, and when push comes to shove, he even goes as far as to attempt to bury Ranma deep in the woods to get her to stop (but can't do it).
In Akikan!, Najimi, drunk off soda, is revealing her true feelings and asking Kakeru to do the deed with her, not caring that there are other people around. Kakeru is moral enough and declines.
Dee spends the majority of FAKE trying to coax Ryo into having sex with him, but when Ryo, emotionally shaken after meeting and being unable to shoot his parents' murderer, comes on to him, Dee backhands him and tells him not to tempt him into taking advantage of him in an emotionally vulnerable state. (He does subsequently try to find out if Ryo really does want it because it's him, but Bikky interrupts them before anything can happen.)
In Tytania, Lira comes on to Fan Hyulick in an attempt to keep him from leaving, as she needs his help to further her cause. Despite the fact that she makes great omelettes, he declines.
Toward the end of To Love-Ru manga, Yami gets a blast of Celine's pollen and asks Rito on a date, then tries to kiss him. While his refusal may've been at least partly for fear of what she'd do to him after sobering up, she interprets it as this trope. Notably, an issue or so later, she doesn't slash or clobber him for seeing her in a swimsuit.
There was an earlier incident where Lala accidentally gave almost everyone in her class a Love Potion. Naturally, Rito ended up having to fend off Haruna's advances.
In My Bride Is a Mermaid, a Love Potion results in Nagasumi having every girl in his school chasing after him. Then when he finally gets home and tries to take a bath, Maki, San, Lunar, Akeno, and Mawari all show up in swimsuits and start coming on to him simultaneously. He ultimately resists, although a side effect of the Love Potion means that San's dad and his own dad both beat the crap out of him.
In Maid-Sama!, when Misaki is hypnotized into acting as though she's drunk and starts trying to take off her clothes, Usui rolls her up in a blanket rather than taking advantage, in spite of having already made his interest in her very clear.
In Trigun: Badlands Rumble, Vash, being the Chivalrous Pervert that he is, could have taken advantage of Amelia when she was drunk, but instead offered to simply carry her home, much to her expressed dismay. It didn't help that she couldn't hold her booze and ended up throwing up on him on the walk back to her hotel room anyway.
In Infinite Stratos, Ichika acts this way partly because he's Oblivious to Love, but mostly because he's the only guy at an all-girls school note in this universe, only females can activate the Powered Armor suits, although somehow he is able to do it, and because of 5 Clingy Jealous Girls, a few with some slight Yandere tendencies, chasing after him and making sure none of the others get a ahead with him.
In Kono Naka ni Hitori, Imouto ga Iru!, Shougo just barely invokes this trope. In episode 3, both Miyabi and Konoe feed him various supplements to boost his virility, then they spend the night with him in his bed, to "train" him to only like girls after mistaking him for being Ho Yay with Mizutani.
Omamori Himari's Yuuto's other superpower must be his ability to not be swayed by the (extremely aggressive) advances of every Cute Monster Girl in his harem.
In the 4th Fairy TailOVA, the girls get drunk. Juvia comes on to Gray (though she would do that even if she wasn't drunk) and Lucy comes on to Natsu. Gray freaks out the whole time, Natsu freaks out for a bit but then carries Lucy to her room and puts her to bed.
Code Geass R2 has a Gender Flip. Lelouch has a Heroic BSODbecause Nunnally has become viceroy of Area 11 and stumbles upon Kallen, who idolized his alter ego and is tsundere to Lelouch himself. He approaches her, cups her check, and orders her to "comfort me". Not only she refuses because he's not himself, but she smacks him across the face.
In Kotoura-san, Manabe won't take advantage of Haruka even when he has a decent opening, despite his blatant perversion. This is with him, quite literally, trying to force himself to follow through on his intentions (with Haruka's grandfather's blessing no less); he can't bring himself to act anything less than honorably in Haruka's presence ("honorable" for a horny Manabe, anyway).
In Ayashi no Ceres, Aya offers herself to Yuuhi, looking for Sex for Solace for loosing Toya. Yuuhi gives in at first, to the point of making out and both getting naked. However, right before going too far, Yuuhi snaps out of it after seeing Aya being clearly on the brink of tears. He then kindly rejects her, claiming that he loves her too much to take advantage of the situation.
Y: The Last Man gives Yorick, the literal last man on Earth, plenty of opportunity to parlay his status into physical gratification. However, as he himself explains it, he would not feel right taking advantage of women like that.
In the Firefly fanfic Forward Jayne is rather (pleasantly) surprised when River suddenly starts trying to make out with him. However, he quickly realizes something is wrong, then douses her with ice water to snap her out of it. Shortly afterward, they learn that there's a psychic who has been influencing everyone around them, and that said psychic was deliberately pushing River and Jayne at each other because otherwise River would have been observant enough to recognize said psychic.
Happens sometimes to Raven in Teen Titans fanfiction due to one episode showing her emotions as distinct personas. When a certain one takes over...
A Brief History of Equestria: One side story has Hurricane comfort Clover on the death of her father by sleeping with her... strictly in the platonic sense, even stating he'd never think of taking advantage of her emotional state like that.
In Consequences Of Unoriginality, Emeris spends the first chapter under a curse that, among other things, forces the mares and sometimes stallions around him to throw themselves at him. Despite the resulting loneliness, he never takes advantage of it and manages to resist all of the more forceful attempts (eg, drugs, Fluttershy's stare), though sometimes merely through dumb luck.
The protagonist of Sophistication And Betrayal resists giving in to Fluttershy after a night of drinking, as it would only result in meaningless drunken sex.
This is a common plot device in fics that pair Lyn with Kent in the Fire Emblem fandom. Kent's straightlaced and lawful personality, mixed with his romantic feelings for Lyn (which are canon in the game), are supposed to make him keep any pushiness or selfish tendences aside in regards to a relationship with Lyn, and possibly "aid" them in a Hurt/Comfort scenario. Whether it works or not in the fics, eh, it's a case-by-case scenario.
"I want you inside me." "Go ahead - no, I can't. Sounds like you got at least at least two people in there already. Might be a little crowded."
This happens to the central couple in 10 Things I Hate About You, with the girl drunk after a party. Rather than think of the male lead in a new light after discovering he is too noble to take advantage of her, the female lead hates his guts for seeing her in a moment of weakness.
In The Cutting Edge the poor hero refuses the drunken Defrosting Ice Queen, she reacts very badly and yells at him, he goes off alone and depressed and gets very, very drunk, and then The Vamp turns up and lacks his nobility...
Superbad uses this, although having sex is the point of the teenager's plan. It does have him getting together with the girl at the end. It's also subverted somewhat, as Jules is completely sober, and Seth is very much drunk.
In The Bobo, Peter Sellers' character declines a drunken offer from Britt Ekland's courtesan character to take advantage of her, possibly because he'd made a wager that he could seduce her, but it had to be in her apartment where it could be confirmed.
There's Pinto in Animal House, who gallantly declines to take advantage of his 13-year-old date who has passed out (to the disgust of his Shoulder Devil).
In Machete, the hero declines a drunk Sartana's advances and merely sleeps with her in his arms. When she wakes up and realizes he didn't take advantage of her, she falls for him.
Eli in The Book of Eli, for obvious reasons, refuses Solara's solicitations. When she tells him that he needs to use her, lest her mother be beaten, Eli allows her to stay and report that she was... used.
After downing the wrong potion, one of Harry's lady friends is feeling rather grabby. Much worse is the fact that Dresden is naked, and they're stuck in a rather small protective barrier that would break should they do anything, and she'd rather grope and tell him to take her right there. There's a bit more than chivalry going on in the situation though; there's a large demon waiting outside the barrier, waiting for them to break the barrier. Look, It Makes Sense in Context, okay?
In the short story Last Call Harry has a chance to have a threesome with a magically-drunk and very willing Murphy and a goddess (Greek, since you asked). Not only does he violently resist, he also refrains from telling Murphy that she came on to him after the spell wears off.
All of Harry's interactions with Lara, the current, de-facto head of a species of succubi. Also, with Madeline Raith. It helps that he's protected by love.
Harry once worked on the set of a porn film. That's how he met Lara, incidentally. When asked if he had tapped that, Harry notes that he's still breathing, so he had to be this trope.
In regards to his apprentice, Molly. Her dad is one of Harry's two best friends.
The Summer and Winter Ladies, several times. The Winter Queen, Mab. Later subverted with Mab when Harry becomes her Knight.
Lasciel can appear to him as anyone, and do anything with him and it'll seem real.
Harry is surprised when Marcone makes Harry a platinum member of his "health club". Harry and Marcone both know that Harry is this trope in regards to Marcone's... "trainers", but Marcone was doing it so that Harry would be too distracted by the good treatment to blow up any of Marcone's buildings. Again.
The Drizzt Do'Urden novels feature a scene where, possessed by her sword (long story), Catti-brie rushes into Drizzt's room wearing a flimsy nightdress and glomps him. He spends a couple minutes with his brain and hormones going haywire and almost gives in... then he starts adding up certain incongruities and realizes it's not her. They don't get together for years afterward, but their mutual respect jumps several notches.
Lee from the 'Hero Series does this to herself'', at first starting to seduce Taro while high on music, then breaking it off. Then she comes back to get it on after she sobers up.
Kvothe from The Name of the Wind finds it best if he doesn't follow up on Denna's request to join her for a swim in the lake after she's been subject to denner resin.
In Linnea Sinclair's Gabriel's Ghost, Sully's high on some liquid courage and works up the nerve to kiss his long time crush. She resists because he's drunk; if he really wanted her surely he would have made a move when he was sober, therefore it's just the drugs and he'll regret it in the morning. Then he accidentally implies that he's looking for a one night stand, and she gets angry at the insult and walks away.
Dirk in the Second Sons trilogy proves to be Above the Influence when Tia accidentally gets really high on some very powerful aphrodisiac mushrooms.
Jake does this with Dark in the Spy High series. She's not drunk or on drugs, but he knows that she is just desperate for affection and encourages her to have more respect for herself.
Peter turns down a very drunk Leslie partway through the third Rivers of London book, Whispers Underground.
In Ringworld, Nessus uses the tasp on Halrloprillalar in order to enslave her to Louis Wu's will through over-stimulus of her pleasure center. Louis is disgusted by this, and refuses to take advantage of it. Instead, he helps her break the addiction.
Live Action TV
In the Smallville episode "Nicodemus", Lana Lang tries to seduce Clark under the influence of a mind-altering flower. He put up a fight and she ends up "only" kissing him.
The duplicate Dax created from Bashir's imagination in Star Trek: Deep Space Nine is rather...eager. The scene where Bashir is using his tricorder to try and figure out what is wrong with Dax while she is trying to seduce him is hysterical.
In the original series episode "Dagger of the Mind", Dr. Helen Noel flirts with Kirk, but he refuses to reciprocate. Later on, Kirk is brainwashed into thinking he's in love with her and she desperately tries to explain what happened, in fact seeming rather creeped out.
An episode of Malcolm in the Middle had Malcolm get drunk with a girl at a party at Thanksgiving. When the both of them end up well beyond tipsy, the girl propositions Malcolm, and then promptly collapses on the floor, barely able to hold her head up. Malcolm refuses and then ruins his family's Thanksgiving dinner by whining (still very drunk) about how he was too moral to take advantage of her (oh, also by vomiting in the turkey). The next time he sees her, the girl threatens to have her brother beat him up if he tells anyone about her propositioning him.
Stargate SG-1: "The Broca Divide". Let's just say "Carter," "sweet little tank-top number," and "de-evolution" and leave it at that.
In The Big Bang Theory, Leonard gets a kiss from Penny, whom he has been nerdily lusting over (while she's wearing a Cat Girl suit no less), but despite obviously enjoying the moment, he still rejects her on the basis that she just had an argument with her ex and was very drunk.
A few seasons later, a drunken Penny proposes to Leonard (they've been dating a while by this point), and he turns her down.
In "Bewitched, Bothered, and Bewildered", Xander is Above the Influence of every female in Sunnydale, particularly Buffy... well everyone except for Cordelia, who the spell was intended for. The spell was botched, and she ended up the only woman protected from the spell.
Oz is Above the Influence with Willow at more than one point. The first time Willow tries to get him to kiss her, he thinks she is trying to get at Cordelia and Xander and instead he wants to be the gentleman and wait. The second time is after he caught Willow cheating on him, and she tries to seduce him. He lets her down and says she doesn't have to prove anything to him, and rejects her obvious sexual advances.
Also happens with Giles and Jenny Calender at one point, but she's possessed by a demon at the time, so it soon escalates into a big fight.
Family Matters did an episode where Steve Urkel gets accidentally splashed with some pheromones and has to fight off aggressive advances from the normally-hostile Laura. At the end she doesn't seem to remember what happened, and the situation reverts to status quo.
In Friends, although Rachel wasn't technically drunk, her grief over her father's ill health left her feeling vulnerable enough to try and get Ross to console her. However, in spite of their fairly lengthy history, Ross declines, feeling that he shouldn't take advantage of her in her state of mind (later angrily muttering "I haven't had sex in six months, I should get a medal for that!"). However, in an unusual twist, she holds it against him, saying she'd been perfectly aware what she was doing, and just wanted to feel close to someone.
The subject of a hilarious exchange the night Chandler and Monica first had sex:
Chandler: How drunk are you right now?
Monica: Drunk enough that I want to do this. Not drunk enough that you should feel guilty about taking advantage.
Chandler: That's the perfect amount!
There's a very similar scene in the first season of ER. Carol shows up on ex-lover Doug's doorstep, despondent over being denied custody of an abandoned girl, because she tried to kill herself a year earlier. Between Doug's womanizing ways and the fact that it's been obvious from the first episode that he's still madly in love with her, it's painfully obvious that he wants to take advantage of the situation, especially when she begins to make advances to him. But he ultimately resists, knowing that she'll regret it afterwards, not just because of her distraught state of mind, but also, (a) she's engaged to someone else, (b) they've never hashed out the issues from their broken relationship.
Cheers had an episode where a depressed Rebecca gets roaring, sloppy drunk and comes on hard to Sam; notorious horndog Sammy, who's been lusting after her since day one, responds in the negative, and gives two reasons: "One, you've been drinking, and a gentleman has his principles. Two, you look kinda disgusting right now."
In Ashes to Ashes, Gene shows some character development by backing away from a drunk, needy, getting-that-speculative-look-in-her-eye Alex... who proceeds to get even more hammered and jump into bed with the next man who makes eye contact with her, but never mind that.
Averted in House, where Chase finds Cameron high on Meth and wastes no time sleeping with her. They end up married a few seasons later. The justification for this is the 'good girl' Cameron really wanted to bang Chase, and the drugs gave her the testicular fortitude to do it.
It also justified by the way the deed happens: It isn't a high Cameron randomly stumbling across Chase and offering him, but she actively takes the drug and tracks him down to his home to have sex with him.
On an episode of Skins, Michelle breaks up with her boyfriend and practically throws herself at Sid, who has had a crush on her since they were kids. Only he knows she's just doing it because she's upset and that she really loves Tony, who is his best friend, so he ends up refusing her.
Whiskey makes a solid attempt at seducing Topher, mostly in order to Mind Screw him, but he not only turns her down, he is royally creeped out by the whole thing. It likely had something to do with the fact that normally she loathes him.
Echo tries to seduce Paul as well, but he turns her down because he thinks it's because the Dollhouse mind screwed her.
A nasty use of Invoked Trope comes into play on the New Zealand soap Shortland Street, where a girl drunkenly comes on to her psychotic Stalker with a Crush, who murdered her brother, among other people, because said brother wouldn't have been cool with his schoolgirl sister dating his 30 something year old friend. The girl has had a crush on psycho for a long time, but he kinda screwed his chances up when he tried to strangle her for suspecting him of involvement in her brother's death. It's been a while since that happened, but she's still doubtful about a relationship with him. So he shows up, gets her drunk, then invokes this trope when she goes to kiss him. Cue the poor girl deciding that he must be a decent guy, and they get together the next day. It don't work out.
iCarly: The episode ''iSaved Your Life'. After risking his life to push Carly out of the way of a truck, Carly is lovestruck and they enter a relationship. Soon, Freddie realizes that Carly is potentially only in love with him because he saved her life, so he tells Carly they should wait a while, and see if she still has feelings for him later.
In the Firefly episode "Our Mrs Reynolds", Wash manages to resist Saffron's attempts to seduce him. Mal conducts himself quite admirably until she shows up naked in his bed, and most of the crew berates him for "taking advantage" of her... that is, kissing her. He appeared to be in the process of backing out on her when the drugs kicked in.
On Lois and Clark while everyone is under the influence of a Love Potion (except Clark himself because he's an alien) Clark spends a good part of the episode fending off a lovestruck Lois (and at this point in the series, she was still in her Loves My Alter Ego phase).
She also comes close to figuring out his secret identity while trying to seduce him. When she takes off his glasses, she suddenly tells him he looks an awful lot like Superman. Luckily, she doesn't remember much after the potion wears off.
On The Big C, at a party, some of Adam's friends invite him to participate in a gang rape of a drunk girl, but he declines.
On Eureka, Sheriff Carter refuses Allison's advances when she's under the influence of a plant spore that removes inhibitions.
The canon explanation for Degrassi The Next Generation's season finale, though there's really no evidence Sean even knew Ashley was on drugs.
Played With in both directions in How I Met Your Mother, when Robin, after her nasty breakup with Don, tells Ted that she's pretty sure that she'll try to have revenge sex with him in the near future. Ted swears that he'll be Above The Influence, prompting Robin to laugh and explain just how utterly ruthlessly she will stalk and seduce him and have no qualms about exploiting him the first time she catches him in a moment of weakness. However, when she does try this a couple weeks later, the rumors of her wiles turn out to be greatly exaggerated.
Person of Interest: Not with sex, but when Finch was high on Ecstasy (long story) and in a talkative mood, Reese opted out of it knowing that the very private Finch would probably regret it in the morning.
On Copper Corcoran saves Annie from the man who killed and raped her sister and wanted to rape Annie as well. She wants to thank him for all of this by having sex with him. He declines because Annie is only ten years old. Annie had a horribly messed up childhood and Corcoran spends the next year trying to somehow give her a normal childhood while constantly shooting down her sexual advances.
In an episode of Moonlight, Beth gets a sample of a drug called Black Crystal made out of vampire blood. The vampire who makes the drug entices her to try the drug, which will give her the rush of what it means to be a vampire and live in the night, pointing at Beth's beautiful face and how, pretty soon, it'll start to grow old. In a moment of weakness, Beth takes the drug and, later, arrives to Mick's place trying to seduce him. However, it seems she's not trying to seduce him for sex but in order for him to turn her. Mick hold her under the shower but refuses to bite, knowing that this is the drug talking but also himself wishing to be human again.
In one episode of The Drew Carey Show, Kate's mother tries to convince her to dump her current boyfriend, Jay, in favor of Drew. Her meddling results in Kate and Jay going through a rough patch, and Kate, thinking that Jay's about to dump her, gets weepy and drunk and ends up trying to hit on Drew. Even though Drew has loved Kate ever since they were kids, he can't bring himself to take advantage of her under the circumstances.
In Game of Thrones, Tyrion Lannister is wedded to Sansa Stark in a arranged marriage by Tywin. Neither are happy with the predictament as not only is he twenty or more years older than her but their families are at war with the other. On the night of their wedding Tyrion who's been getting drunk all night sees Sansa start to undress and get it over with when Tyrion who's often seen in the pleasure of naked women tells her to stop and that he won't do it and that she won't be harmed by him
"What Kind of Man Would I Be" by Mint Condition is about a man who has a conversation with an old flame who is feeling unhappy with her current lover. Although they are attracted to each other, he tells her that they would both lose too much if they had sex.
"Finger Weg" (Hands Off!) by the rock band ASP: the singer rejects crude attempts to be manipulated by a woman ("Wrap up your flesh, I'm still not hooked. You stand there looking for applause - just get dressed and Hands Off! You think, I know how he's wired. I'm fed up with your tricks, the signals you're sending.")
In Mass Effect 2, you can't complete Jack's romance subplot unless you prove to be above the influence (after all, she won't open up if she thinks you're only interested in her for sex).
Likewise in Baldur's Gate 2 with Aerie, who will break up with the player for having sex with her prematurely. Normally, the ME2-plot would be somewhat of a recycling, but since Aerie and Jack more or less are polar opposites...
In Odin Sphere, the only thing Oswald really wants is for someone - anyone - to love him, to the point that he only agrees to kill a dragon for King Odin after Odin offers him his daughter Gwendolyn's hand in marriage as a reward. But when Oswald is told that Gwendolyn is under a spell that will make her love the man who wakes her, he flatly refuses to do so and instead goes out on a mission to find a way to undo it.
During Kyou's route in CLANNAD, Ryou takes a joke Tomoya makes a little too seriously and pretty explicitly offers to sleep with him. However, he declines as he feels it wouldn't be right since he doesn't really love her. Not that he really admits that part yet, instead reasoning that it's far too early in their relationship for something like that.
At one point in Hanako's route, she gets quite drunk and becomes very clingy with Hisao. He gets very uncomfortable and tries to put her to bed as quickly as possible before either of them does something they'll regret. He even lampshades how wrong the idea of taking advantage of the poor girl is.
Something similar happens with Rin after she takes just a little too much cold medicine (active ingredient: codeine). When Hisao visits her, she's only in her shirt and panties and gives him a kiss, but he puts her in bed as well and she forgets about it in the morning.
In Shizune's route, a neither drunk nor high-on-meds but very emotionally unstable Misha asks Hisao to "comfort" her. Whether he is or not above the influence this time, unlike the others, depends on the player's decision. If he's not, it leads to the Bad End.
True Love Junai Monogatari has two instances of this, in which the MC will have to be above it if he wants to get the girl. Namely, he must not kiss Ryouko after a fight with her brother and manager (the correct option is walking her home) and/or he must give Yumi-sensei a hug instead of pushing her on her bed. (In a subversion, the second one leads to sex anyway.)
It's explained early on in Erfworld that lower-ranking units will do whatever their superiors tell them to do. It's also implied (and later stated) that while the beings of Erfworld don't reproduce sexually, they do have sexual relations. Parson puts two and two together, and realizes that as a high-ranking strategist he can have his pick of women, without them ever objecting or even conceiving of rejecting his affections—and immediately after thinking of this as "awesome," it hits him hard that this is essentially rape, and he reconsiders (he does spend a lot of time with female soldiers, but apparently he's trying to romance them).
Maggie is surprised that he hasn't taken advantage. The reason he tells her is that the scale difference (they're all at most a quarter his size and half his height) squicks him out and brings up the issue of causing physical injury.
In Bittersweet Candy Bowl's chapter "Another Shoulder", Lucy goes to Paulo after getting shut down hard by Mike. Paulo just barely resists taking advantage of her throwing herself at him, though a later chapter, "Another Path", explores the possibilities of what would have happened if he hadn't.
Angus in Questionable Content refuses Marigold's advances toward him while she was drunk, although she truly did have feelings for him.
Also Claire and Marten in more recent comics. The feelings are there, but when they realize they're both drunk, they decide to wait.
Subverted in Dumbing of Age, where Danny refuses a girl's advances in the spirit of this trope, and is later told off by Ethical Slut Joe because there was no influence, and assuming a woman doesn't know when she wants sex wasn't the respectful option at all.
