Det. Danny Reagan: Yeah, why?
Sabrina: Let me ask you something. What does she got that I don't have?
This trope is when a character who is married becomes immune to seduction because their marriage is a happy one and/or they have a strong sense of honor/propriety. It is often a sign of maturity as well as a show of being a good spouse. Many people are envious of their faithful and happy relationship. Sometimes paired with a lech to show the dichotomy. Count on this guy to be the one who keeps a cool head when the lech would fall apart.
Truth in Television: Even in this era of more relaxed sexual morals, a lot of people still take marriage vows seriously and will rebuff any attempts by third parties to seduce them. Equally, someone who is genuinely happily married will likely be getting adequate quantities of reasonable sex, which helps to blunt the effectiveness of seduction attempts; they won't be desperate.
Similar to Celibate Hero, as the character certainly recognizes the hints, but simply feels no urge to reciprocate due to being in a relationship. Sister Trope to Sorry, I'm Gay. Often overlaps with One True Love. Someone using a Wedding Ring Defense is trying to invoke this trope. Contrast I'm a Man; I Can't Help It, All Men Are Perverts, and Your Cheating Heart.
- Futari Ecchi has Makoto and Yura, being the story of how they get married as 25 year old virgins and figure out sex together while growing as a couple. Yura is just so pure that she would never think of sleeping with anyone but Makoto. Makoto has strong perverted tendencies which include pornography and ogling other women, which sometimes extends to having an Imagine Spot where he sleeps with someone besides Yura... but at the same time he's Oblivious to Love regarding any woman besides Yura actually wanting to get with him in reality, and he would never willingly betray Yura because he loves her and wouldn't want to make her cry. He only gets into a couple of close calls because he's a bit of a pushover and sometimes gets roped into situations because he can't say no. He actually became such an unintentional Chick Magnet after getting married that various women try to seduce him, including his co-worker Makie, a girl at a beach resort, and the young new receptionist at his company who also fell for him, but he has preserved his virtue nonetheless. Word of God says that Makoto and Yura will never cheat on each other.
- In Fushigi Yuugi, Miaka and Tamahome (or better said, his reincarnation Taka) get married later in the story and invoke the trope. It tuns out to be a problem since a later antagonist, Mayo Sakaki, is a girl with one hell' of a crush on him...
- Old joke: A man wakes up with a killer hangover. Fearing his wife's reaction, he crawls into the kitchen where he finds an enormous hand-made breakfast waiting on the table, with his wife gone to work and his son waiting for him. When he asks his son what this is for, the son replies "Well last night, you puked all over the doorstep, you crapped yourself and you tripped into Mom's favorite vase." "But why's she being so nice to me?" "Well, when she was trying to get you out of your dirty pants you shoved her away and screamed 'Fuck off, I'm married!'"

But the man's wife is relieved to see that he has absolutely no interest in a sexual encounter, and instead he has killed the alien and is dissecting her on the coffee table.
- Dark Victory plays with this, regarding Two-Face. Harvey Dent still regards himself as married to Gilda, but his Two-Face identity isn't, so he invokes and ignores this trope whenever it's convenient. For example, he fights off Poison Ivy's pheromones by remembering his love for Gilda. He also has an affair with another woman, the new DA, Janice Porter, but when he decides he no longer needs her:
Porter: Tell them, Harvey! Tell them that I love you and you love—
Two-Face: Harvey Dent is a married man, Porter. Don't ever forget that.
- In What About Witch Queen?, while not married to Kristoff yet, Anna doesn't even think about any men other than him, even when there's a naked sailor in a bathtub right next to her.

- Shrek and Fiona. This is especially shown in Shrek 2. Both clearly love each other dearly and have no interest in anyone else. When beautiful women hit on Shrek when turns into a handsome human, he informs them he already has a true love. With Fiona, her father learns this after attempting to force Fiona to be with Charming and has a Heel–Face Turn, realizing he can't force Fiona to fall in love with Prince Charming so he decides to go back on his promise to Fairy Godmother.

He is presented with a female human who has been raised by them (these are aliens who don't wear clothes), and when she asks if he would mate with her if given the chance, one of the reasons he gives for not wanting to is that he is married. Since the aliens also don't practice marriage, this doesn't really explain much to her, especially since she has already had sexual relations with a teenager who claimed he had a girlfriend back on Earth.
- Invoked by John of Rhodes in the Belisarius Series when he says he is not really such a Casanova as rumored because he looks carefully to see who is seduceable and Antonia is completely unseducable, being Happily Married to Belisarius.
- Played with in Against the Tide of Years, when Marian Alston and Swindapa, a married lesbian couple, visit a war chief and are offered a woman as part of the Sacred Hospitality. Alston, who takes marriage very seriously, has absolutely no interest in the girl, but Swindapa, who comes from a culture in which polygamy is the norm, is intrigued, even though she doesn't take advantage. This is somewhat par for the course in their relationship; throughout the book, Swindapa is rather shameless about her wandering eye, even though she never does anything more than look and occasionally enthuse.
"I promised to be monogamous, not blind."
- The Wheel of Time:
- Mat Cauthon is a ladies man bordering on Pornomancer territory. Late in the series, he becomes married to the Seanchan empress Because Destiny Says So. Even though it's effectively an Arranged Marriage that looks like it will be completely sexless, he is scrupulous about honoring his vows, turning down several opportunities to get some on the side. (Fortunately for him, They Do eventually, though with hilarious Do You Want to Copulate? overtones on her part.)
- Perrin is able to shrug off powerful mind control that should make him utterly loyal to a particular villainess, by remembering that he loves his wife.
- In I, Jedi, crime boss Leonia Tavira tries to seduce Corran Horn, who's gone undercover in her Space Pirate gang to find his wife Mirax. He is massively tempted, briefly tries to rationalize it, then decides it's the Dark Side of the Force talking.

- In Twilight, the bond between vampire mates is totally permanent, so much so that even the Volturi's Mind Control powers can't break it apart.

- In Mikhail Akhmanov's Trevelyan's Mission series, the titular character loves the ladies, and his job as an Alien Among Us in primitive humanoid cultures typically requires him to use any means of achieving his goals, which, to his delight, often involves sex. Later in the series, however, he meets an Amazonian Beauty and proposes marriage by the end of the novel (after knowing her for a few days). Being from a conservative planet, she insists on an exclusive marriage, and he agrees, even promising to avoid sex when on a mission. In the following novel, a female from a race of beautiful Human Aliens with far more relaxed views on relationships and love tries to seduce him, not comprehending why he refuses her. He understands that she has no way of knowing about human marriages but still punishes her for her actions. Instead of stopping completely, she then shifts her focus to his wife, suggesting a polygynous relationship, pointing out that it's not uncommon on Earth only to receive a reply that, as a woman of T'har, she has old-fashioned views on marriage.
- In Captain French, or the Quest for Paradise, the titular character has been married many times over his extremely long life (all of humanity is The Ageless). While no one expects "until death do us part" to still hold up, given that people no longer have a natural end to their lives, French still obeys the vows he gives in each marriage until it ends. At one point, a woman tries to seduce French at a party using an aphrodisiac perfume. He nearly succumbs to it and to the fact that her Buxom Is Better breasts literally pop out of her blouse, but manages to snap out in time and use his cigar to keep the woman at bay. He then take his wife to their hotel and "relieves the pressure" from the aphrodisiac to the point where she half-jokingly calls him an animal in the morning. He also teaches a man, who asks him for advice in seducing French's wife, while offering to introduce him to several local girls, by giving him the exact wrong advice and watching his wife angrily hit the guy. Sure, he understands that the guy didn't think he was doing anything wrong by the mores of this planet, but still...
- Subverted in The Handmaid's Tale. The protagonist, Offred, was married before the dystopia started, but reasons that being a Handmaid isn't adultery, since it's necessary for survival. However, consensual sex with the family's attractive servant is definitely adultery, so she rejects him despite being extremely tempted. However, later she has to have sex with him for the chance of surviving...but winds up doing it many more times, anyway. (For what it's worth, she was "the other woman" while her husband was married to somebody else.)
- Spenser is often propositioned, but he is committed to Susan (despite being "not exactly married").
- Jamie Lannister in A Song of Ice and Fire is not married (because he legally cannot for various reasons), but has been committed to Cersei for his entire life despite being a Chick Magnet whose handsomeness is renowned through the Seven Kingdoms. He notes wryly that despite the 'immorality' of their relationship this makes him one of the only faithful men in Westeros. He is rather disillusioned by learning that Cersei doesn't reciprocate.
- Firefly: In "Our Mrs. Reynolds", Wash resists Saffron's advances due to this. Saffron just loses her temper and clocks him on the head. His wife is suitably impressed and pleased. (In the previous scene, the unmarried Mal didn't stand a chance, and Inara only avoided being ensnared because she has the same training as Saffron and recognized the approach.)
Wash: Wuh duh ma huh tah duh fong kwong duh wai shung,trans. do I wish I was somebody else right now. Somebody not... married, not madly in love with a beautiful woman who can kill me with her pinkie!
