I never thought I'd die this way... But I'd always really hoped!
"O'Grady, he was eighty, though his bride was just a pup, He died upon the honeymoon when she got his Irish up"
— Da Vinci's Notebook, Another Irish Drinking Song
When a character dies in the very act of sexual intercourse, to the shock, embarrassment, or mortification of the still-living partner. In many cases, the cause of death is a heart attack or stroke — which is generally Played for Laughs. If the moment was particularly heated, the character may also Go Out with a Smile.
Alternatively, someone may be killed through other means during sex. If it's murder, then the killer may do it to get their jollies, or because that's when the victim is particularly vulnerable.
One type of Death by Sex. Contrast Mate or Die, where the character must have sex to live.
Not to be confused with a person blowingthemselves up, or with people deciding to make their demisea memorable one. Also not the same as Coming and Going; although that also juxtaposes sex and death, the people involved don't have to be the same people.
Truth in Television for some people, although the chances of someone having a heart attack from getting too excited during sex are very slim. (Unless he's a smoker or diabetic.)note As told in Don't Put That in There! And 69 Other Sex Myths Debunked by Dr. Aaron E. Carroll and Dr. Rachel C. Vreeman Also true for some animal species.

Anime and Manga
In the Battle Royale manga, Mitsuko Souma forces herself on already-dying Yuichiro Takiguchi, because she thinks it will "make him better." She stabs him to death out of frustration when it doesn't. This is not played for laughs. At all.
In Blood+, Diva's rape of Riku is implied to have either directly caused his death (through the... fluid transference) or directly preceded her killing him by giving him her blood.
In episode 2 of Kaiba, a woman has intense sex with Kaiba's body, into which she has copied her memories. The ominously heightening experience, coupled with thoughts of her father, results in an explosion, covering the entire room with what appears to be green blood.
Happens in extremely graphic fashion near the beginning of Urotsukidouji.
In the Ninja Scroll movie, the ninja Kagero is the poison tester for a feudal lord, because her body is immune to poison. Unfortunately, her body is also filled with poison, and thus sex, or even physical contact, with any man will kill him.
Subverted in that the antidote to the hero's poisoned state is to have sex with her.
In a Shout-Out to the above, Basilisk has Kagerou, a female ninja "blessed" with the ninja skill of having her breath turn into instant-death poison when she's aroused. The results of this are seen a bunch of times, too. You'd think it obvious that raping a ninja lady is not a good idea. Too bad the guy who DOES rape her is... well, immortal.
Basilisk also had Okoi, a ninja who pulled her opponents blood out of their bodies via skin contact. Guess what her favorite method of getting close enough is.
Similarly yet again, this is the point of the Poison Princesses. Their poison-exporting kingdom uses them to get rid of troublesome political opponents.
A PG variant of this appeared in Mahou Sensei Negima!, after the World Tree causes Nodoka's request for a kiss from Negi to turn him into a kissing-obsessed Determinator. Asuna is quick to point out that if he actually kissed anyone in that state, they could die due to suffocation. When Negi finally ends up kissing her, she actually faints before the magic wears off and he turns back to normal.
In the second chapter of Franken Fran, Fran heals a crippled girl by making her part insect. When she goes to a love hotel with her new boyfriend after her convalescence is over, she instinctively eats her mate.
The very first demon we meet in Berserk takes the form of a beautiful naked woman who lures men into sex with her so that she can transform into her true form and eat them alive. She is killed by Guts in the very first scene of the manga when she tries this on him and gets her brains blown out the back of her head with his Arm Cannon. But during the Eclipse, we get to see this Apostle in action when she eats Corkus alive.
The M.O. of an assassin in an early Lupin III chapter.
In Bleach, Bambietta Basterbine will sometimes call a subordinate to her room for sex, but she was a nasty habit of killing them. Her friends complain, but she doesn't care.
At one point in the yaoi manga Under Grand HotelSwordfish has sex with Sen to the point where Sen would have died if Swordfish wasn't stopped by guards.
The "Little Deaths" storyline of Powers focuses on the police investigation of a philandering Captain Ersatz of Superman, who died at the climax of sex with one of his (many) lovers. In a rather tragic twist on the matter, his secret identity was married and his secret wife, upon being bombarded with the news of how her husband lost his life, killed herself.
In "God Is Dead", new goddess, the crimson-skinned goat-legged Gaia distractedly announces to her female acolytes "Yes, yes, tell my followers I love them. Now...I need a man." in the next issue, a man is on her bed and she is seen sliding onto the bed with him. Elsewhere in her fortress 2 women are talking, and the man's screams are heard. One woman looks up and casually says "The goddess will require new bedsheets." After events elsewhere, cut back to the entrance to Gaia's bedchambers, as 2 women are carrying the old bedsheets between them with the unfortunate man's dismembered limbs sticking out.
In The Sandman, a minor Running Gag is the thought of going out "between two nubile virgins, crushed by an elephant at the moment of ecstasy." In Death's story in the anthology "Endless Nights", someone actually pulls this off (ringing a bell to cue the elephant, if you were wondering). And lives to tell about it, thanks to some Alchemical Phlebotinum that sticks a small island in a sort of "Groundhog Day" Loop.
In WANTED, the Professor mentions killing his arch-nemesis by giving his lady friend a radioactive condom.
Common in the Ramba comic series. Two particularly disturbing incidences (from the same two-part story) are a woman being raped to death by a man with a blade attached to his penis, and a woman being drowned in semen.
The Host of The Darkness dies if they conceive a child, and the Darkness will make sure he does if he ever has sex. There are loopholes, however.
Cinder, one of the members of Deathstroke's new "Titans" team of killers, is first seen having sex with one of them that sucks out your Life Energy. It doesn't help that her current form is based on the protagonist's subconscious ideal of the perfect woman, so he's obsessed with her at the same time as he's trying to track her down and kill her.
"Check me on this, please ... Aphrodite killed at least fifty rebel gods, and incapacitated not less than 250 others for, well, we can assume several days at least, one of whom is Zeus himself ... in a bedroom-Olympiad that ran over two days?"
In the comedic essay-fic, Equestria: A History Revealed, this is apparently the way the Equinus Republic fell, in an induced mass orgy between the ponies of parliament that devolved the nation into chaos. The author even makes a pun about it.
And so the Equinus Republic went out not with a whimper, but with a bang. Several of them probably.
Kuso Miso Technique's Abe Takakazu in this fan video kills a guard by raping him. Which doesn't make much sense until later when it's shown all gay men have lightsaber swords for penises.
In the Touhou doujin Though the Wind Criesa man who lost his entire family in the drought blames Suwako for it. He then proceeds to rape her as she is going through quite a severe Heroic BSOD and does no resistance. However during this, something snaps inside of her and she kills the man during the act.
In the movie, Trouble Shooters: Trapped Beneath The Earth, a hotel is sunk underneath the ground when an earthquake opens a giant sinkhole.

"Now THAT is how I'd like to die."
In the 1981 Made-for-TV MovieThe Star Maker, Rock Hudson (as Danny Youngblood) drops dead in bed while having sex with a very young (possibly underaged) girl. Ed McMahon (as Lou Parker) makes jokes about it at his funeral.
In Species II, most women who sleep with the man infected with alien DNA die from a five minute pregnancy that bursts their stomachs. Curiously, a woman similarly infected died the same way, instead of healing.
In the low-budget Clay Pigeons, Vince Vaughn gets revenge on Joaquin Phoenix's behalf by murdering his ex-girlfriend during sex... with Elvis playing in the background.
Happened to Goldie Hawn's character's husband at the beginning of the film Private Benjamin.
At the funeral: "What were his last words?" "I'm coming."
Basic Instinct opens with a woman murdering her partner during sex. With an ice-pick. Ouch.
The detectives actually share a BIG laugh over this trope, when they find out it's what happened:
"Looks like he got off before he got offed!"
The Madonna vehicle Body of Evidence opens with a wealthy man dying from a heart-attack caused by indulging in cocaine and the stress brought about by having extremely passionate sex with his younger girlfriend. The resulting court case asks the penetrating (pun definitely intended) question of whether "sex was the murder weapon".
Done for laughs in the Thanksgiving segment of Grindhouse.
The political scandal in The Birdcage is the result of this. "Louise, I'm the Vice President of the Coalition for Moral Order! My co-founder has just died in the bed of an underage black whore!"
In Se7en, the Lust victim suffers a particularly gruesome form of this, via bladed dildo.
In The Distinguished Gentleman, Eddie Murphy's character runs for Congress because he has the same name as the Congressman from his home district, who has a heart attack while boffing his secretary at a party.
In the porn-spoof FleshGordon, the evil emperor Wang fires a Sex Ray at Earth from his planet Porno, causing humans to go mad with lust. People including pilots who should be at the controls of their airplane instead.
"We're going down!"
"Oh, yes, please!"
In an unintentionally funny scene in Malcolm X an old friend of his is shown to have died of a heart attack during sex, while still on top of the girl who's now screaming her head off.
In Barbarella, a Mad Scientist tries to kill the title character with the "Excessive Machine" that gives lethally powerful orgasms. Barbarella not only survives, she overloads the machine. She is then vocally disappointed to learn that the machine is broken.
The Hidden (1987). While possessing the body of a stripper, Puppeteer Parasite-like alien screws a man to death in the parking lot. It's a bit unclear exactly how this is done.
Cherish in Cecil B. Demented. The FBI must have some crack snipers if they can hit someone between the eyes, when they're bouncing up and down like that.
A killer prostitute in Kiss of the Dragon asks her victim things like "Do you want to go to heaven?" and "Are you ready to go to heaven?" as she's riding him to (his) orgasm. He asks her to take him there. Mortality ensues.
In Internal Affairs II, the capo "Gandhi" gets suffocated with a plastic bag by a "masseuse" when he's expecting a different kind of "happy ending".
In Spies Like Us, Chevy Chase even says the line. Perfectly subverted in that everyone in the group of spies and Soviets gets to have sex with someone, and then they figure out how to disarm the nuclear missile and avert world obliteration.
In 11:14, Aaron and Cheri are having sex in a cemetery when part of a damaged stone monument breaks off and falls on his head.
In the screwball comedy Sibling Rivalry (1990), The one-night stand of Marjorie Turner (Kirstie Alley) dies during a wild rumpus. This lands Marjorie in a fine mess.
The 2011 film The Victim begins with a stripper played by Danielle Harris dying of accidental head trauma while being raped in the woods.
In Patriot Games, one Irish assassin is a redheaded beauty who chokes her target during sex at the beginning of the movie.
Very Bad Things: The death of a stripper while having rough sex with one of the guests at a bachelor party is what kicks of the Plethora of Mistakes that drives the plot. This is one of the more believable instances: she doesn't die because of some perfect storm scenario involving an unusual medical condition, she dies because they're doing it in the shower and she hits her head hard on the plumbing.
Cabin Fever features a moment where the diva is convinced that there is no escape from the deadly disease going around. Rather than actually trying to flee the infected area, like most of her friends, she resigns herself to her fate and decides to spend her last minutes gettin' her freak on. Grabbing the nearest available man, she gets naked in the blink of an eye and rides the dude to her last moaning madness. She was in such a wild mood the guy didn't even have time to put on a rubber. Pity for him that it turned out she had the disease while they were doing the deed bareback. You could say he went out ''from'' a bang.
In a German sex horror film called Rossa Venezia, the killings are touched off by a wife coming home to find her hunting-crazy husband in bed with a pretty young thing riding his lap. As quietly as she can, she picks up his elephant gun and lets her have it in the back of her head. Just so happens they were climaxing at the same time too, making this a twofer for the unlucky gal. She then proceeds to flip the hell out and rampage across Germany Mrs. Vorhees style, killing anyone she sees 'doing the deed' or just having done it. For less of a bang but still a bang, she executes a couple of other women with electrified dildos.
Dave. The president suffers what apparently would have been a fatal stroke were it not for all the life-sustaining measures taken—a later scene when his wife meets with his doctor make it clear that that there's no chance for recovery and that he's only being kept alive by machines—while shagging his secretary. This kicks off the whole plot, with White House staffers secretly replacing him with Dave, a look-alike.
Done literally in one of the latter Wishmaster films, when one of the characters wishes for "killer sex".
In Wishmaster 2 a prisoner wishes his lawyer would go "fuck himself". Wish granted.
In Revenge in the House of Usher: Zombie 5, the resurrected wife of the Mad Scientist has a very odd way of getting her revenge on the villainous Doctor Orloff as his last act on Earth: she threatens to make love to him. He reacts with horror.
Scott Pilgrim Vs The World has an unusual take on this trope. In the Scott/Ramona vs Roxie fight, Scott defeats Roxie by poking her in the back of the knee after Ramona tells him that it's her weak spot. Roxie immediately has what is unmistakably an orgasm, and bursts into a giant pile of coins.
In Infernal Affairs II, a high-ranking Triad member is suffocated with a plastic bag by an assassin posing as a prostitute, while they're having sex.
An old joke, somewhat NSFW: Two people are having sex in the back of a car when the man suddenly has a heart attack whilst still joined with his partner. The woman freaks but can't get him off her; she nevertheless manages to summon help, who get the emergency services to come out. They determine that the only way to get him out of there is to take the roof off the car. The fire department saws the roof off the car and manages to get the guy out, and as the paramedics are taking him away a police officer tries to comfort the woman, who is sobbing hysterically. She says "Don't worry, your husband's going to be fine." The woman replies "Fuck him, he's not my husband. It's my husband's car, though." Ba-dum-tish.
Another joke: An ambulance is called early one Sunday morning to the home of an elderly couple, the paramedics find them both naked in bed - him dead, her weeping. When the paramedics ask what happened she explained: "Well my husband had a weak heart, but we both still wanted to have a sex life. So we'd only have sex once a week, timing our thrusts to the sound of the church bells to keep it slow.... if only that fucking ice cream van hadn't come along!"
Three nonagenarians are chatting.
Abe: I see old Zachary died last night. That's how I'd like to go - suddenly in bed while I sleep.
Bob: You're right about suddenly, but that is way too boring. I want to die in a spectacular high speed car crash.
Charlie: You both have it partly right. I want to die suddenly, spectacularly and in bed.
Abe: How does that work?
Charlie: I want to be shot dead by a jealous husband.
Tomorrow in the Battle Think On Me (originally Mañana en la Batalla Piensa en Mí), the book by Spanish author Javier Marías, is about a man whose lover dies in his arms while having sex.

Roulette, from Wild Cards, has the superhuman ability to fatally poison men having sex with her, and she is manipulated by the Big Bad into being a hitwoman for supers.
In Storm Front, begins with Harry being called in to help investigate the deaths of two people who took this to the extreme - magic caused both of their hearts to explode messily out of their chests mid-coitus. Justified as Harry theorizes that the strong emotions during sex amplified the magic attack.
Also, White Court vampires (who are succubi and incubi) can kill with sex, especially if they're seriously injured and need to feed intensely.
Lord Raith was such a boss White Court that he used to use this power as an opener at parties by ''kissing'' someone to death, something that takes most of his kind the duration of sex, so minutes instead of seconds. Then Margaret LeFay McCoy neutered his demon and linked that curse to her bloodline, so as long as Harry and Thomas are around, Papa Raith can't Feed, and therefore can't do this. He also can't be a superbadass vampire, like his kind can on occasion, because he can't restock the reserves that he would draw on by being a badass.
Also, also, in White Night, when Molly gets to re-experience someone's 'out with a bang moment' thanks to a White Court vampire. This makes things very awkward for Butters and Dresden, who were watching, expecting pain and despair rather than an orgasm.
Butters: Is she above age?
Dresden: Um, yes.
Butters: Good. Now I don't feel quite so Nabokovian.
[Cue comments about needing to get out more.]
In Cold Days, Harry reveals that he considered asking Lara Raith for this if Kincaid refused to kill him.
"I mean, hey, if you’re going to go, there are worse ways to do it than to be taken out by the freaking queen of the world’s succubi."
After witnessing a... rather unpleasant death, Injun Joe remarks that he'd rather go in his sleep. Harry, on the other hand...
Harry: I want to be stepped on by an elephant while having sex with identical triplet cheerleaders.
A strange aversion in the third Vlad Taltos book, when the main character decides (for no good reason) to have sex with the female assassin who just killed him (he got better, evidently); later, thinking back, he notes that he was wondering whether she would kill him before they finished.
In Harry Turtledove's Timeline-191 series, Lucien Galtier dies, after a long and eventful life, of a heart attack during the act. This event provides the transition to his son-in-law, the new viewpoint character, who helps his wife, Lucien's daughter, deal with her grief via gallows humor.
In Turtledove's Darkness Series books, an officer decides to tie up and rape a hot spy for no particular reason and sends his soldiers out of the tent. She manages to get to a razor and slit his throat (though it is implied to be after he finishes) before cutting her bonds and escaping.
Setup for Chuck Palahniuk's Snuff: An aging porn star is shooting a world-record gangbang and may or may not die at the end of it. A lot of the book is other characters arguing about whether this result is intentional and/or inevitable. The actual ending manages to be much more embarrassing.
In the beginning of the Star Trek: New Frontier series, the Vulcan Selar is consummating her Pon farr with her mate when he dies. This merely delays the Pon farr for a little while. She eventually consummates with Burgoyne, the hermaphrodite engineer.
A particularly disgusting variation of this occurred in John Connolly's short story The Cancer Cowboy Rides.Buddy Carson seduces a drunken waitress and has sex with her; however, on the second round, the waitress begins to feel the effects of Buddy's unique gift- fast-acting cancer transmitted by touch: tumours, black blood, and a slow and agonising death that Buddy watches eagerly.
In Larry Niven'sRingworld, one of the humanoid species is a race of "vampires" that use cranked-to-eleven pheromones to draw in victims of the opposite sex from other species, with almost invariably fatal results.
Gene Wolfe's "There are Doors" had an alternate Earth where humans have a very different reproductive cycle; after sex women store men's semen in their body for the rest of their life, and can use it to have as many children as they wish. Men die, as their immune system shuts down.
It's all but stated outright Kitiara from the Dragonlance books has killed men while or after having sex with them.
"How's the Nightlife on Cissalda", a Harlan Ellison story about the human race ending because people were too busy having sex with aliens to eat
"Man of Steel, Woman of Kleenex", an article by Larry Niven explaining—in VERY close detail—exactly why Superman could never have a Superboy and why this trope would be the likely outcome of any mating with Lois Lane or other non-Kryptonian females.
"With kryptonian muscles behind it, Kal-El's semen would emerge with the muzzle velocity of a machine gun bullet."
(This appears to have been totally ignored by the modern-day DC Comics which have established Clark and Lois as a married couple who, presumably, have a non-lethal sex life.)
In Angels and Demons, the assassin's final atrocity was to be making the leading lady give him head and slitting her throat as he came. Foiled, thank God.
Discussed in Zolang er leven is by Renate Dorrestein. A widower realises that there was nothing he could have done to prevent his wife's death, but he could have been making love to her instead of fighting.
In Dan Brown's Digital Fortress, an obese man hires a prostitute. Because they came into possession of an item that the hitman was tracking down, they were murdered while in the act, as the hitman's instructions were to kill anyone who had even seen it.
In the book Snap Shot by A.J. Quinell, the Mossad agent Misha Wigoda is killed this way by the SDECE's agent Janine Lesage at the end of his interrogation. This was because, even though he was on Valium they couldn't extract any useful information from him until they discovered the lust Janine was producing in him. They used this to extract the information they wanted from him. Janine always wanted to kill a man while having sex as she had heard that when that happens the victim gets a monumental erection.
In The Kingkiller Chronicle, every man that Felurian meets dies of exhaustion after having sex with her. The rare few that survive emerge with their minds shattered beyond repair. Kvothe is legendary for being the only man to ever survive with his mind and body intact.
The Jennifer Morgue has Ramona Random, a CIA agent with a succubus bound to her soul who usually kills by these means. It leads to a nasty predicament where one of her targets has a heart attack during sex, and she needs the little death to go with the big one or the awakened succubus will eat her soul as well.
In Time Scout, someone conjectures that sex with Margo would kill you. His interlocutor implies that it would be worth it.
In Michael Ely's Twilight of the Mind, a Sid Meier’s Alpha CentauriExpanded Universe novel, the daughter of the imprisoned Sheng-ji Yang kills her husband, the new chairman of the Hive, by placing a poisoned device in her vagina and getting him to forget his distrust of her long enough to seduce him. As soon as he penetrates, he gets injected with a fast-acting poison, while her guards take care of his guards. Thus she becomes the new Chairman Yang.
In the Forgotten Realms novel Daughter of the Drow by Elaine Cunningham, female-on-male murder during sex is called "the spider's kiss" among the drow (in reference to their spider goddess Lolth, among other spidery things in their culture). The title character, wizard/cleric Liriel Baenre, actually subverts it, however, as she instead knocks her lover unconscious to save him from a group of Vhaeraun worshipers.
In The Albino Knife, Marcus Jefferson Wall has his consciousness transferred into a cloned mastodon, which then suffers a stroke while having sex with an elephant. It Makes Sense in Context. (This is a subversion, as the scientists who transferred him manage to pull him back out in time. Marcus is undamaged.)
Roger Zelazny's Roadmarks featured a woman who specialized in killing her partner at "the moment" so he was coming and going at the same time.
The Sano Ichiro book The Perfumed Sleeve, Sano's rival Makino dies during a threesome; his partners flee in panic, and his manservant finds his body and tried to "clean things up" so it looks like his master died with dignity.

The Soft Ones in Isaac Asimov's The Gods Themselves reproduce by "melting", an extended period of time in which they physically merge with their other two partners. Afterwards, one of them gives birth. The children's sexes always occur in a specified order, and all the members of the triad die after the birth of the third child. Subverted because we eventually discover (along with the viewpoint Soft Ones themselves) that they don't actually die, they permanently merge and become a "Hard One", which up until now the Soft Ones and the reader have been led to believe is a different race. This also occurs temporarily during the other meldings, though the Soft Ones retain no memories of this.
Averted, sort of, by Cheryl in John Ross' Unintended Consequences. She's about to be retired as a mob boss' toy, so he gives her to one of his lieutenants who's infamous for getting bitey with his playmates. Fortunately for Cheryl, when the big moment comes, he doesn't notice the rock maple hairsticks that she uses to lobotomize him, and the thrill of escape helps her get off.
In the Star Wars Expanded Universe, it's revealed that the H'nemthe have evolved (naturally or socially, it's not clear) this trait due to their 20 males to 1 female gender ratio. The females, who are otherwise vegetarians, eviscerate their partners after sex with their razor-edged tongue and they sincerely believe this is actually the greatest expression of love between the sexes. One of the short stories in Tales from the Mos Eisley Cantina revolves around an alien Corrupt Bureaucrat named Feltipern Trevaag wooing and having sex with the alien identified in the movies only as "Yamnose", here revealed to be a female H'nemthe named M'iiyoom Onith. When the inevitable happens, the folks who clean up the mess consider Trevaag to have truly been Too Dumb to Live, not only for trying to sleep with a female H'nemthe, but for not realizing the GeniusBilingual Bonus in her name; "M'iiyoom" is the H'nemthe word for "Nightlily", a beautiful but carnivorous flower that uses its sweet scent to attract prey.
What happens to any Mortal who has — or tries to have — sex with a Caster or Incubus in The Caster Chronicles. It's doubtful how far anyone would actually get; just a heavy make-out session with Lena nearly kills Ethan in Beautiful Creatures. He would have died, had it not been for Ryan's intervention.
In A Song of Ice and Fire, Sansa meets Lady Myranda Royce, a widow her own age whose middle-aged husband expired the first time they had sex.
Myranda: He died on top of me. In me, if truth be told. You do know what goes on in a marriage bed, I hope?
Sansa: That must have been dreadful, my lady. Him dying. There, I mean, whilst...whilst he was...
Myranda: Fucking me? It was disconcerting, certainly. Not to mention discourteous.
Also discussed by Tyrion, who, when asked how he wishes to die, replies, "At the age of 80, in my own bed, with a girl's mouth around my cock."
While it doesn't need to be fatal, Melisandre is implied to drain the life out of people she has sex with and use it to fuel her magic. After doing so twice with Stannis she says she can't do it again, lest she kill him.
For a nonlethal variation, the novelization of Star Trek: The Motion Picture gives this as one of the reasons Deltans who enter Starfleet swear an oath of celibacy. Because Deltan sex involves a merging of minds as well as bodies, a non-Deltan who sleeps with one risks insanity by doing so. Captain Willard Decker enters into a relationship with Lieutenant Ilia knowing full-well the risk.
In David Eddings's Tamuli, the emperor of the Tamul empire is required to marry a woman of each subject kingdom at the same time, (there are 9 subject kingdoms) and then consummate with all of them that night. After mentioning this, Emperor Sarabian recalls that his grandfather had not survived the night.
In Rainbow Six, part of the villains' testing of their lethal-if-not-vaccinated biological agent involves getting uninfected captives to have sex with infected ones while both sides are drugged. True to form, said virus can be spread by intercourse.
Live Action TV
Hill Street Blues: When Michael Conrad died in 1983 (due to a urethral cancer), his character, Sgt. Phillip Esterhaus also died. How did he die? Suffering a massive heart attack while making love with his girlfriend, Grace Gardner. (Several episodes that had been completed prior to Conrad's death were aired in late 1983-early 1984, prior to the airing of "Grace Under Pressure," although his last appearances had him only appearing "at roll call.")
On an episode of M*A*S*H, a visiting general goes out this way with Major Houlihan... Hilarity Ensues as the general's aide de camp spends the second half of the episode trying to find a battle into which he can bring the general's corpse. The idea, of course, is that instead of going out with a bang, the general — in the public eye — will Go Out With a *BANG*.
In this episode, the main suspect, a very overweight woman, accidentally suffocates her partner when she passes out drunk on top of him. The woman actually told the police that she smothered him with a pillow, because she said she would rather confess to murder than suffer through the jokes that would be made about her because of the true nature of the victim's death. Believe it or not, the show handled this with a degree of sensitivity.
Picket Fences did a similar story, but without the sex: an obese woman didn't want to admit that she'd rolled over in her sleep and smothered her husband by accident, so she claimed to have done it deliberately.
The third season episode "Clyde Bruckman's Final Repose" had the titular psychic suggesting that this would be Mulder's death: "You know, there are worse ways to go, but I can't think of a more undignified one than auto-erotic asphyxiation."
In the same episode Clyde also predicted he himself would die in bed with Scully. This ended up being true, as he died in bed, and Scully was in the room. He was in bed, and with Scully, but not in bed with Scully Ironically, he dies in a way similar to how he predicted Mulder would die, but the way he asphyxiates himself is likely suicide.
Ha'Gel from Earth: Final Conflict. Very similar method of death for his victims. Of course, he was desperate, as he seemed to be the Last of His Kind. He essentially rapes both Sandoval and Beckett to produce Liam, the hero of seasons 2&3. Liam doesn't seem to acknowledge his alien parent any more than he absolutely has to.
Supposedly fated to be Lister's death long after the events of Red Dwarf. "He chokes to death, aged 181, trying to remove a bra with his teeth." The source of this information does not have a stellar record, however.
He does seem to have a penchant for that kind of thing, though... in the episode "Timeslides" he gains a Portal to the Past and tweaks things a little, so that he does not go on Red Dwarf and instead dies in a plane accident, aged 98. He was having sex with his fourteenth wife and lost control of the plane.
The Angel episode "Lonely Hearts" had a parasitic demon that kept a constant stream of hosts by emerging from the current one and, er, "penetrating" a partner during sex, killing them and coming to rest in their body. Not during, after. While cuddling.
Parodied on Seinfeld, where one episode includes Kramer passing out (while not during sex, the situation seemed headed that way). The woman he passes out on top of contacts her relative (brother?) who has mob connections, and Kramer wakes up in the East River.
In the Star Trek: Deep Space Nine episode "Let He Who Is Without Sin...", Dax's previous host Curzon is stated to have died having sex. (With Vanessa Williams, so, justified.) However, this directly conflicts with Jadzia's Orb vision of her symbiont implantation in the pilot (where Curzon is very much alive), and with her account of Curzon dying in a hospital bed in "Blood Oath" (where he is said to have died in a hospital bed a day or so after Dax's removal).
The One-Gender Race of Taresians in Star Trek: Voyager create male Taresians to mate with by implanting viruses into other humanoid species to lure them to their planet, making them believe that they were long-lost children.

The concept of this trope gave rise to this classic observation on the British show Mock the Week: "There are those who say there is no good way to die. These people have obviously never heard the phrase drug-and-sex-fueled heart attack".

Subverted and then played straight in an episode of Chicago Hope. A man has a very bad blockage in his heart and shows up to get surgery. It turns out the doctor is an old flame of his. He doesn't tell her about his heart condition, instead acting like the only reason he's come to town is to see her. (Which isn't entirely a lie. It was really both reasons). They end up having sex and he has a heart attack during it. He actually lives for awhile afterwards since the doctor took the necessary steps to preserve his life and got him into surgery immediately. But while in recovery, his wife shows up.

Another cheater was inadvertently given nine times the recommended dose of Viagra - his wife snuck him three, he took three before he went to see his mistress, and she slipped him three. Needless to say, it was fatal.
A couple likes to do it out in the open. They have sex on top of an old and malfunctioning electrical transformer. The dude had just gotten a "Prince Albert" cock piercing, and once it touches the transformer... BZZZZZZT! He gets electrocuted to death. (The girl lives, but only because her feet weren't touching the ground, thus not completing the circuit.)

The Tick kills off the Immortal (a Superman-expy) with a heart attack while under Captain Liberty. Given the... erm, frizzy part of her hair in the following scenes (and the paired scorchmarks in her ceiling), it's evident he wasn't in full control of his heat vision during the act...
Rose: Oh, there was something wild about him that night. Although I did think it was strange when he started yelling, "Rose, I'm going! I'm going!"
And this also apparently happened with one of her boyfriends, though it was more likely after the deed, not during.
Happens in almost every episode of Silk Stalkings. Sometimes more than once. One example stands out in "Where There's a Will": a wealthy man is murdered by his younger partner when she handcuffs him to the bed and forces him to take a sexual performance enhancement drug that aggravates his heart condition. The man starts begging her to stop when he realizes what's happening, but she ignores him and continues to ride him while he's suffering a fatal heart attack.
Happens in one of the later episodes of Twin Peaks as a hot 20-something gets married to a 70+ year old who happens to be the Mayor's brother.

("All he was wearing when they found him was a pair of socks and a big grin..." he mutters.)

(He spends most of the episode trying to convince himself that he has to.)
On Mr. Belvedere, George is distressed to learn that one of his friends died this way, and is subsequently very reluctant to make love with Martha. She finally manages to seduce him by telling him, "At least you'll go out with a smile." He suddenly remembers that his friend did indeed have this expression on his face and they fall out of sight.

Bill Hicks had a bit where he talks about his ex-girlfriend, and how he fantasizes that one day, she'll be having sex with her morbidly obese, abusive husband, and he'll die mid-coitus, right on top of her, slowly crushing her to death, and bile and blood and tobacco-laced saliva will spew out of his mouth into her face, and just before she drowns, she turns her head to the TV, "...and I'm gonna be on it!"
In his third Evening With... DVD, Kevin Smith talks about the requirements for being canonized, and says it helps dying in the name of God, which means you could be in the middle of coitus, and suddenly clutch your chest and cry out "Jesus!" and you'd be "Saint Nutsdeep, Patron Saint of Dying While Fucking".
Richard Pryor claimed that this is how his father checked out; "My father came and went at the same time".

That ain't enough time. Everyone clogging up the road; you ain't getting no-place! Me, I know a woman I been wanting to be with for ten years.. I would RUN over to her house; I'd say "baby (pant) we got fifteen, (pant) fifteen minutes!" And hope I get a nut just as the bomb go off!"
In Warhammer 40,000 this is apparently the only way to have sex, especially when Slaanesh is involved, and especially when the Dark Eldar are involved.

In the Rogue Like game NetHack, there are incubi and succubi who might have sex with you (incubi for female characters, succubi for male characters). When this happens, there is a chance that "You feel exhausted", and you lose some hitpoints. If you die because of this, it's considered "overexertion". There is also a chance of leveldrain. Unless you wear proper "protection", then it's just HP loss.
Subverted in Phantom of Inferno, where Drei informs the badly wounded main character that she wants to go out like this as commandos approach the building they're in.

Some asari of the Mass Effect universe have a rare genetic defect that kills their partners during sex. These asari, known as Ardat-Yakshi, grow smarter, stronger and deadlier with each encounter, and it is an addiction to them, such that upon diagnosis, the Ardat-Yakshi is given the choice of living in isolation or being executed. In Mass Effect 2, Samara's loyalty mission has you going after an active one of these by the name of Morinth, who uses her condition much like a serial killer, and has been doing this for 400 years. You can choose to recruit her on your team, and get it on with her — with predictable results.
Subverted in the same game with Jack; Mordin warns Shepard late in the game that this is a possibility if you're pursuing a romance with Jack. He hypothesizes that Jack might lose control of her already unstable biotic powers and accidentally kill Shepard mid-coitus. If you do consummate the relationship, however, nothing of the sort actually occurs.
A similar aversion also occurs with Tali, except in this case Mordin is afraid that she'll be the one to die due to her species' degraded immune system. However, Tali's smart enough to take the right precautions and comes out of it with nothing more than a nasty cold. And even then, she admits that it was totally Worth It.
Sengoku Rance has the Ninjas themselves. Hell, Suzume has a few like poison on her breasts, a drug that would burst whenever someone came inside her, and so on.
Similar to the Mass Effect example above, in Fate/stay night the Makiri lust worms do this to women. Basically (to quote the game), "The worms will transform when attacking a woman, so that they are only able to violate her nerves. They will spread their tentacles all over her body and devour her spirit. The lust worms will wet the woman's skin with their mucus, excite and destroy her central nerves of pleasure, and satisfy their hunger. It must be their instincts, as the worms seem to love the woman's womb. They do not eat female flesh, but seek the organs within them. They give the woman huge enough orgasms to fry her brain, and they go into her body to devour her placenta. Unwilling to eat human flesh, the worms have only one way to get what they desire. As a result, the woman's mind and body are completely violated and destroyed." And these worms are basically penises with More Teeth than the Osmond Family.
Katawa Shoujo treats this seriously because it is a very real danger for the hero, who has a weak heart that can fail from too much excitement and/or physical exertion. Usually he's able to keep calm enough to avoid any problems, but at least one h-scene is cut short due to him coming extremely close to having a heart attack.

F.E.A.R. 2: Project Origin's ending changes the context of several life-threatening scenes throughout the previous game, making this implication clear.

Natsuki of Sexy Losers dies of exhaustion from too much sex.
Magarce from Tally Road experiences this trope almostliterally. If it were not such a shocking and gratuitously furry image, the latter would almost be a perfect trope-illustration- except that she's not actually dead, just 'out'. One can only assume she has an (ahem) Made of Iron.
The protagonist of a risqué webcomic Bad Bunnynote Best remembered for "offscreen turducken porn" joke. The site disappeared after the author died. is a rabbit in love with a dog twice his size.

As shown by the image above, three skeletons of previous victims are seen nearby with crushed pelvises and very satisfied expressions.
Zapp: What are you, gay?!
This would appear to be based on a joke that goes something like this:
Two men exploring a jungle are captured by a native tribe. The two men are given a choice: Death, or Unga-Bunga. The first man chooses Unga-Bunga and is immediately raped by all the men of the tribe. After that, the second man chooses death. The tribe leader declares: "DEATH BY UNGA-BUNGA!"
