Whenever a character with the Powers of a GodTM hooks up with a mere mortal, there is nearly always a bit of lurking Fridge Logic which may or may not get addressed in the show itself, especially not if the show is aimed at kids. Expect fanfic to address it, quite a bit. Namely, that there is a very wide gap between one partner's physical strength and the resilience of the other's flesh, which can be an important factor during particularly, hmm, intimate encounters between the two.
Regardless of the trope title, any gender combo can be involved, though the Steel/Kleenex problem generally comes up in pairings where the 'steel' member is male. "Man of Kleenex, Woman of Steel" is somewhat less common, though it has lately received more consideration.
The trope also seems to assume sex is mainly or only involves a (traditional, heterosexual) missionary position, versus the couple being more, well, imaginative about positions, activities, etc. (and thus finding ways around such problems).
- Dragon Ball: People have wondered how three ultra-powerful Saiyans (Goku, Vegeta, and eventually Gohan) manage to have kids with three human women (Chi-Chi, Bulma, and eventually Videl). Of course, it's not like they had any other options for choosing mates, as no female Saiyans survived.
- However, the characters in Dragon Ball Z have to power up before they can use their full power. Even prior to the Cell Games, which is when Goten was conceived, Goku was able to master the basic Super Saiyan form to the point where he could control his strength in said form at all times. Basically, if they have to power up to become stronger, they can probably power down until they are at average human strength, and even if they do not power down for 'intimate moments', they also seem to have a great deal of control over their power level. As in, they can pick up an apple without crushing it, or open a door without taking it off the hinges, etc...
- The fact that they can suppress their power levels, probably means they can choose to be weaker than they normally are.
- Another factor is that most of the love interests are unusually strong as well. Even Bulma is tougher than average; Chichi and Videl have martial arts training, and 18 is a superpowered gynoid. While their powers may not compare to the godlike levels of a Super Saiyan, it can at least allow them to survive occasional lapses in control, such as the time that Goku accidentally threw Chichi into the stratosphere.
- Project A-ko: The long-dead fansite Anime Marriage Prospects discussed this in regards to title character A-Ko Magami, saying this (paraphrased): "Six words: Vaginal muscles that can crush steel. Have fun."
- Dance in the Vampire Bund has a mental illness example. The only way for a lycanthrope father to guarantee his son will also be a lycanthrope is to have sex with his wife while transformed. Sannin's mother was driven insane by the experience coupled with the sight of the newborn "hairy, inhuman thing". Akira's mother didn't get off much better. Though she wasn't driven insane, she did end up wheelchair-bound after delivering a second werewolf son.
- Surprisingly, this comes up in Shakugan no Shana. Luckily, there's an unrestricted spell that temporarily grant its target strength equal to a flame haze.
- In Kamisama Kiss Nanami, an Ordinary High-School Student, ends up falling for Tomoe, a Little Bit Beastly Kitsune. In addition to Super Toughness, Tomoe also sports quite a few magical powers such as shapeshifting and control over fire. He becomes more and more concerned about Nanami's safety as the story goes on, saying things like "I've got to be careful not to get her broken."
- InuYasha: Kagome is a normal human teenage girl, while Inuyasha is a half demon who can lift boulders with one finger and take a sword through the chest without receiving any permanent injuries. He also has razor sharp claws on his fingers that cannot be retracted. While they never do get significantly intimate in the anime or manga, it's not hard to imagine how this could cause some problems farther down the line as their relationship progresses.
- Uchi no Musume ni Te o Dasu na!:
- Clara is a demigoddess, which grants her Herculean strength, stamina, and durability... along with a nigh insatiable libido.
- Her girlfriend, Mei, is a teenage human with power over soul latex. They've had sex several times; including one instance where Clara banged Meinote several times in succession, without letting her rest, 'til Mei finally passed out from the pleasure and sheer exhaustion. So it's a wonder how Clara's managed to do it without ripping her apart.
- Immediately following the aforementioned incident, Clara flew to N.U.D.E's HQ and proceeded to ravish the entire staff; including her three best friends: Risa, Kisara, and Jun. By the time Athena arrived to answer their distress call, Risa was bodering on delirium from Clara having done the same thing to her:
Risa: (dazed) "Please... no more. If you thrust it inside me anymore... I'll go crazy. Please, forgive... Clara." (faints)
- Superman and Lois Lane, as discussed in the Trope Namer essay.
- Lois and Clark have been shown to have sex, even on panel (though non-explicit, of course). It's generally just assumed that Superman has enough muscular control that he can basically turn his powers off, save invulnerability, even during orgasm. Since he doesn't accidentally destroy the Earth every time he sneezes, this theory has at least a little Fridge Logic behind it.
- John Byrne's Superman & Batman: Generations offers a logical solution: Superman crafted a pendant that mimics red sun radiation, which Lois wore during her pregnancy to keep the super-powered fetus from kicking a hole in Lois' belly while she's pregnant. After their daughter Kara started developing powers, she was given the pendant to keep them in check until she was old enough for Dad to teach her how to use them. Presumably, Supes wore the pendant when he was intimate with Lois.
- Inverted with Kara and her boyfriend/fiancé Bruce Wayne Jr. (Batman III), but while it's shown that they do have an active love-life there's no mention of it causing any problems or of any necessary countermeasures like the red sun pendant.
- Some imaginary stories showed the couple getting a place in Kandor, with its highly advanced medical science, and Lois staying there while pregnant and having the kid (or kids).
- In an alternate timeline in Armageddon 2001, Lois Lane does carry Superman's child, but one kick from the child causes internal bleeding in the mother, ultimately resulting in Lois' death.
- Also inverted with one of Superman's enemies, Maxima. Her primary motivation in most continuities is to get with Superman or some similarly powerful man because most other men are too weak to survive a few rounds. (In the animated series, she was overjoyed when Lobo turned up a few moments after Superman made his farewells to her.)
- Invoked almost word for word in Superman: Earth One Volume Two, when Pa Kent has "the talk" with Clark and tells him that since he's different from normal people... "well, man of steel, woman of tissue, that's all I'm saying"
- Note that in continuities where Superman's powers are explicitly derived from prolonged exposure to yellow sunlight, the "kicking fetus" dilemma should be moot, as the offspring wouldn't actually encounter such sunlight until after birth.
- As of DC Rebirth, this is averted,since recent issues of Action Comics show Lois giving birth to Jon.
- This was implied in a parody that featured Superman helping with a police investigation regarding a group of women (and one man in the bathroom of a gay bar) who had all died by what appeared to be a shotgun blast to the back of the head.
- Superman's cousins Supergirl and Power Girl are the female version. Super-strong Kryptonian women whose muscles can crush steel. Have fun.
- Similar issues have been raised regarding The Flash and the potential for creating friction burns in some very sensitive places.
- Thor and Jane Foster probably.
- In Anita Blake Vampire Hunter, all the super strong lycanthropes have to be careful of their strength while having sex. One of the things that Richard likes best about Anita is that due to being a human servant of a vampire she's much less fragile than a regular human and he doesn't have to hold back so much.
- Fantastic Four: Many fans shudder at the logistics involved in Alicia Masters (a woman of average build and height) and Ben Grimm (either a rock golem or at least covered with rocks; either way he's huge and about as wide as he is tall) consummating their love. Many fans claim that their love, while romantic, is non-sexual. It's suggested several times in the comics (including jokes from Johnny) that The Thing completely lacks genitalia.
- Hilariously given a Lampshade by Johnny in the second film:
I'd hate to wake up one morning and find out she was killed in a rockslide!
- Hilariously given a Lampshade by Johnny in the second film:
- The Inferior Five has a less common inverted example, with the super-strong heroine Dumb Bunny ("Strong as an ox, and almost as smart!") in love with ordinary human Merry Man ("He was a 90-pound weakling... until he lost weight"), but afraid of crushing him.
- The Boys: While the woman survived the experience (raped by an evil Superman Captain Ersatz), she didn't survive the pregnancy: the superpowered baby cut its way out of her womb with heat vision. Even without that example, it's clearly said early on that having sex with a supe is no laughing matter, to the point where prostitutes hired by them have to take a special drug to deal with it.
- In another issue, some superheroes hired by the Russian mafia leader, Little Nina request some more prostitutes to alleviate their boredom, but she refuses because the first ones apparently died from the sex.
- Inverted and referenced in an issue of Stormwatch with a "woman of steel, man of kleenex" who get around the problem by being very careful about it.
- In the superhero parody comic The Pro, the titular "working girl" heroine is giving The Saint (a Superman parody) a "job" when he tells her to move quickly. The resulting shot takes down a plane.
- Not related to super-strength, but the X-Men's Rogue. As she found out when her powers manifested themselves during her First Kiss, if she remains in physical contact with anyone for very long, not only will she absorb any powers they may have, but will absorb their memories and ultimately kill them.
- The reverse is lampshaded, at a point where Jennifer had limited control over her transformation, and preferred to stay in She-Hulk form. Her boyfriend doesn't appreciate it, especially the risks involved in having sex with a super-strength individual.
Jen: And if things get too... you know, just use the safe word.
John: No kidding. I've got a few more "safe words," like "Ow!" and "Dear God!" and "Crushed pelvis."
- Speaking of She-Hulk, this trope is lampshaded in Old Man Logan, when Bruce Banner explains that the only woman who could "take the pace" with him was "little Jenny She-Hulk." Yes, this would be about as controversial and Squicky as you are imagining.
- This is despite the fact that the Hulk has been shown to not suffer from this problem; while it's generally accepted that Banner can't have sex without risking a transformation, the Hulk has had sex with normal human women on occasion, though most of the Green Giant's love interests have had considerable super strength and durability, themselves.
- The reverse is lampshaded, at a point where Jennifer had limited control over her transformation, and preferred to stay in She-Hulk form. Her boyfriend doesn't appreciate it, especially the risks involved in having sex with a super-strength individual.
- One XXXenophile story featured a lesbian version of this trope — human female discovering that sex with a troll female is very painful for the human, mainly because the troll has no idea how to control herself while intimate. They find a way to turn the human into a troll, and problem solved.
- The Plutonian of Irredeemable had this taken Up to Eleven with the fact that even touching his hair could cut the hand of a normal person. He was eventually able to get around this problem with a magical candle that rendered him mortal as long as it burned near him. The first time he uses it is to consummate his secret relationship with one of his teammates. In a dark deconstruction of this trope, it's implied that this taste of freedom may or may not have had something to do with him ultimately pulling a FaceHeel Turn later on.
- The Savage Dragon is a large green-skinned humanoid with superhuman strength that was shown having casual sex with a number of human females. This trope comes into play when his secret backstory reveals that he is from an alien race and even stronger than his kind as result of being their "chosen one". When a female of his species offers herself to him, the next panel shows he tore her apart with his super strength. And she was just one of the many women before that this happened before! Its probably the reason why uses more restraint now with his sexual partners.
- Khaal: The Chronicles of a Galactic Emperor: Khaal is a super-strong Half-Human Hybrid who is mentioned to have killed several female Psycogs in bed, despite them being capable of enduring and recovering from such relations. With that said, he is shown having sex with other normal women without problem, despite being a very rough partner.
- While not an example of super-strength, there have been some fans of Black Canary who hope for her partners' sakes she isn't a screamer in bed.
- Inverted with Guy Smith, codename Mr. Sensitive, of X-Force / X-Statix: his powers make him extraordinarily sensitive, so normally he wears a special suit to dampen his powers enough where he isn't constantly in agony. When the possibility of intimacy is brought up, he reveals that he also has a special ointment that can numb his senses to normal human levels for several hours.
- PS238: G-rated version. After Tyler (as Moon Shadow) pays Julie a compliment, she gives him a big hug and flies off. Since she has super strength (and he has no powers at all), she nearly crushed his spine and didn't even notice. Tyler's mentor recommends keeping his face mask to deter super-strong heroines from trying to kiss him, and later Julie hugs Tyler so hard that she accidentally traps him in his metal pilot's seat. It's worth noting that in this series we do see the children of superheroes and Muggles, including the Captain Ersatz versions of Superman and the Incredible Hulk, so clearly there's some way around this trope.
- Über: This problem is brought up when the Super Soldier Sieglinde is about to go on a probable Suicide Mission and wants to have sex for the last time, but her new physiology means that any normal man would easily be ripped apart by her strength. So she has sex with her fellow Super Soldier Markus, whom she actually hates because of his Psychopathic Manchild personality.
- Supergirl's problems haven't entirely escaped various fanfiction writers' notice any more than Superman's have. In 1997, one such writer named "tooshoes" wrote the highly NSFW story "What Are Supergirls Made Of" in which Supergirl explains that her steel-crushing vaginal muscles would indeed make a eunuch out of any ordinary man who tried to have sex with her. In this story, despite what Niven says against this in his essay, Supergirl finally persuades Superman that she and he are indeed a good match for each other.
- "The Price of Justice" plays with this in the course of Black Canary investigating a series of strange deaths that resemble close-range shotgun blasts to the head.
- In With Strings Attached, Paul gains Super Strength and realizes to his horror that he can never have sex again. This hits home when he's given the option of schtupping a whole village full of Nubile Savages.
Paul was quite intrigued by the prospect of banging his way through a bunch of women straight out of a teenage fanboy's imagination... until he thought about what he would do to a woman beneath him.
- "Days of Futures Past What Does That Mean It Kinda Sounds Sexy" a crossover fic of Naruto and Young Justice has Naruto saying that Superman might have let Project Cadmus acquire his DNA and make Superboy due to Superman not being able to have a son naturally without tearing a woman in half
His jizz is probably like an AK 47.
- Second-generation Combat Cyborgs in A Numbered Existence and In The Service present an inverted case, as they must consciously control their strength to interact with normal objects or normal people without breaking them; they also weigh twice what someone of their height and build would normally. Several of them lament the fact that there's only one male they know who wouldn't have their jaw broken by a passionate kiss; being a ten-thousand-year-old combat construct he's on their level of strength and resilience. Their dating prospects improve considerably when the Time-Space Administrative Bureau copies the Combat Cyborg design for their own troops.
- Common enough in Teen Titans fanfiction. Normally averted with Cyborg - when he is capable of having sex (either due to modifications or the necessary parts being saved during the accident), it would make sense for his robotic parts to have enough precision. However, Starfire has Super Strength (and, in a couple of fics, has to finish on top due to her Eye Beams being released during orgasm), while Raven has telekinetic powers connected to strong emotion, with the results ranging from "levels the tower and half a city from a few kisses" to "can have sex after a few days of meditation" to "just needs a bit of practice to limit damage to a few broken lamps".
- From Bajor to the Black: Eleya, a Bajoran, briefly mentions a Noodle Incident where she had Three-Way Sex with two Klingons and woke up "with a hangover and several bruises in embarrassing places".
- Subverted in Last Child of Krypton with Shinji -who is Superman in this crossover- and Asuka. At the beginning, it looks like they're going to have this trouble... until it's revealed Asuka is an Amazon, and nearly as strong as Shinji. In the final story version, she becomes a Kryptonian via bio-engineering.
- In the Superwomen of Eva 2: Lone Heir of Krypton crossover, Asuka and Shinji have this trouble since he's human and she's Supergirl.
- In Supergirl (2015) fanfic A Favor Among Friends Kara considers to have sex with Mon-El because being invulnerable he's the only unrelated male she can have sex with.
But the real problem about being a girl from Krypton on a planet orbiting a yellow sun, is the invulnerability. The imperviousness to outside forces trying to penetrate yeah Kara cringes at the thought, because shes not just invulnerable to speeding bullets and randomly tossed street signs. Shes invulnerable to all of it.
All of it.
- In Smallville fanfic Under the Influence, when Kara introduces herself to Clark and reveals she's a Kryptonian she adds: "So I'll not break."
- A minor plot point in Call Me Kara, where Kara and Barry's inability to have sex without her possibly killing him is the main reason that she has Cisco create a red sun radiation bracelet, which multiple characters refer to as her red solar radiation sex bracelet. Luckily, they learn to get around this by using Barry's powers to make him durable enough to not die.
- In Superman fanfic Superman of 2499: The Great Confrontation, the issue is brought up when former Superman's wife Lyra states Kryptonians can control themselves; otherwise, she'd have no children.
- In Geek of Steel, a Jake 2.0 fanfic, Jake namedrops Larry Niven to express his concerns about his Super Strength. Diane's not familiar with the essay, or apparently even with Niven's work in general.
- Defied in Superman fanfic "Call Me a Sinner, Call Me a Saint" when Lana Lang wants to have sex with Clark Kent and brushes his concerns off: she knows he's able to control his strength and "it'd be an amazing way to go" anyway. She's proven right.
- Also defied in Supergirl story "Girl of Steel". Kara admits she could seriously injure Barbara, but contrary to laughable rumors she can control her own powers.
Super speed could put her in a wheelchair and Kara would like to avoid putting her there. She had good control over her powers and strength, not to rip people in half. Unlike what some geeks on the Internet would have to say, she had perfect control. She wouldn't break people just by fucking them.
- In Dark Titans, Ryoga and Raven can't ever getting intimate because it would result in him unwillingly crushing her body while she fries his brain.
- Invoked by Romance and the Fate of Equestria. Big Macintosh is the pony equivalent of One Head Taller to average mares, and Fluttershy isn't particularly small, but is definitely meek and delicate. Before the two of them sleep together, Big Mac expresses a fear that he might break Fluttershy's pelvis when they do.
- Lies, Damn Lies, And Statistics: Described as a problem, in the chapter "Alicorn of steel, little pony of tissue". It's stated, perhaps not entirely seriously, that attempting to woo an alicorn is considered evidence of a mental disorder.
- Implied in Hellsister Trilogy when Kara states she never had sex before meeting fellow Kryptonian Dev-Em. Given that all of her previous boyfriends were baseline humans...
- Reflections Lost on a Dark Road: Ryoga is afraid of becoming intimate with Nabiki because of his immensely greater strength and toughness.
- The Secret Return of Alex Mack:
- When Charlie O'Neill manually stimulates Hanna to orgasm, she injures his hand when her legs clench up.
- This prompts Alex to wonder how Azure Crush manages to have sex without killing her boyfriend Sergi. A later side story reveals that Crush has indeed broken some ribs.
- Subverted in Kara Of Rokyn. Clark Kent and Lois Lane are able to have sex safely, but when Lois gets pregnant Superman still has to come up with a way to prevent Lois from getting killed by her baby.
- Downplayed in A Prize For Three Empires when Carol Danvers and Gladiator link hands. She is super-strong but he is still strong enough to shatter her bones accidentally. At the same time, he is careful enough to control his own strength.
Carol: In this context, it would often be significant, indeed. Just keep it as gentle as that, Glad. I know you could break my fingers.
Gladiator: But I would not.
- Discussed in Child of the Storm. Warren, who has wings beyond razor-sharp, dumped his former girlfriend because h's (somewhat justifiably) worried that one twitch from him could lead to a potential girlfriend getting cut in half. Harry points out that his dad is Thor, a Physical God whose Super Strength can level mountains, and his almost-stepmom is a woman who's petite even by human standards, and yet they have regular sex—it's all about The Power of Trust (though it doesn't hurt that Thor is roughly 1,500 and therefore has had a long time to master his powers). However, Warren seems to take this onboard, because by the second book, he's dating Betsy Braddock.
- Intentionally (if implicitly) averted in The Incredibles in a somewhat interesting manner. In the film, super-strong Mr. Incredible is married to a fellow superhero Elastigirl, but as her name suggests, the aversion of the trope has nothing to do with her being on the same level of Super Strength and Super Toughness as her husband. Instead it's more a case of her powers complementing his, and as evidenced by the existence of their three children, she's apparently just stretchy and flexible enough to "survive" super-strength sex. It also must have made those births quite easy for her.
- Superman: The Movie:
- Superman II. The title character gave up his powers in order to romance Lois Lane, which caused problems when the three Kryptonian super villains showed up. In the Richard Donner cut of the film, Superman and Lois Lane hook up and go to bed together before Superman gives up his powers. Perhaps they attempted coitus and Supes had to back off before the Steel/Kleenex problem killed her, and that's what motivated him to become mortal.
- A Brainwashed and Crazy but otherwise fully powered Superman also has sex with Lorelei Ambrosia in Superman III (admittedly it isn't confirmed but it is very heavily implied). She obviously survived and, judging by her affection for Superman for the rest of the movie, clearly enjoyed the experience.
- The Incredible Hulk movie addresses this (as his heart rate goes up, he has to stop or risk changing). In the comics, this isn't as much of a problem, as it is explicitly his anger, not his heart rate, that causes the change. Because it's his heart rate and not directly anger that unleashes the Hulk in the Marvel Cinematic Universe, by The Avengers, Dr. Banner's mostly able to control it by being "always angry" so that it takes a lot more anger to get his heart rate up (which, unfortunately, would not help him in situations where he can't get "excited"...).
- Hancock plays with the trope for laughs in a Deleted Scene. The titular antihero has a handicap in womanizing because of the projectile lethality of his "projectile liquids".
- In The Time Traveler's Wife, we have an interesting variant. The husband and wife can have sex normally, but the fetus tries to time travel them when frightened — causing several miscarriages. Averted when the wife has a peaceful pregnancy late in the film.
- My Super Ex-Girlfriend has an inversion of this. Matt's apartment is already starting to crumble due to their Destructo-Nookie, and his genitals aren't doing much better either.
- Discussed many, many, many times by Brody in Mallrats, to the point that Stan Lee is a little disturbed by his "obsess[ion] with heroic genitalia".
- Averted in Batman v Superman: Dawn of Justice where Lois and Clark are in relationship that is clearly sexual, as shown in a Bathtub Scene.
- In the So Bad, It's Good film Death Bed: The Bed That Eats, a demon took the form of a man and had sex with a woman, which resulted in the woman being left in a state of half death. The demon cried Tears of Blood on the bed that he had conjured for them to have sex on, bringing it to life as the titular killer bed.
- Discussed by Drax in Guardians of the Galaxy Vol. 2, who mentions that Ego's human-esque avatar has to be... ahem, "fully-equipped" in order to be reproducing with other species, because Ego the Planet is not suited to such a task.
Drax: If he's a planet, how could he make a baby with your mother? He would smush her!
- This comes up as a Can't Have Sex, Ever plot point in the Twilight series. Alternate methods have been proposed (NSFW). It turns out to not be a problem as long as the vampire is married to the human.
- In C. S. Lewis's novel Till We Have Faces, the character Psyche briefly mentions this, saying, "Sister, do you think young gods have to be taught how to handle us? A hasty touch from hands like theirs and we'd fall to pieces."
- A Woman of Steel example: the Rickshaw Girls in M. John Harrison's Light have modified their bodies to Amazonian levels, being very tall and muscled and with much increased stamina as their jobs involve an awful lot of running around towing heavy loads. One points out to her standard human male partner that he needn't worry about being gentle.
- The trope name comes from a 1971 essay by Larry Niven by the same title. It explores several interesting avenues, including the possibility of every fertile female in Smallville getting super-pregnant once Clark discovers super-self-stimulation. He also suggests that Superman may have to carry the baby.
- There's a particularly unfortunate psionic example in Anne McCaffrey's Damia, in which the powerfully telepathic Damia accidentally destroys the mind of her first sexual partner through Power Incontinence while having sex with him. Her father-figure tried to warn her of the dangers of sex with less powerful telepaths, but due to his embarrassment at dealing with the subject she thought he was talking about normal contraception.
- The Cassandra Kresnov novels are about a female semi-organic android (originally designed as a Super Soldier) who, yes, very much enjoys a good roll in the hay. In the third book, Killswitch, Cassandra's acquired a human long-term boyfriend, and in an early sex scene she explains to him why she always insists on finishing up doggy-style: orgasm is about the only time where she can't control her body well enough to be sure she won't accidentally hurt him.
- Alexander,the protagonist of ''The Age Of Ice has ice/cold based powers. When he gets sexually aroused his body becomes icily cold. Being a decent dude he lets his first fiancee Marie know before they tie the knot and she is stuck with him for good, this being when divorce was social suicide. When he falls in love with Anna, who is his fraternal twin's widow he insists on only having sex on bathtub full of steaming hot water to avoid doing harm to her. This causes friction in their relationship even though Anna finds their encounters enjoyable.
- In By Honor Betray'd Ari Rosselin-Metadi, a giant of a man that can casually kill most humans with his bare hands, expresses concern about this trope on his wedding night. His bride Llannat Hyfid (rather athletic, but on the small side) tells him to extinguish the candle, then makes her hands glow with power as she reassures him that nothing they do that night will hurt her.
- In the The Laundry Files books, the nature of vampires in the setting means that any human who exchanges fluids with a vampire is already dead. The Friendly Neighborhood Vampires employed by The Laundry compare this to being HIV positive. Other supernatural creatures, however, are immune to the effect.
- The titular relationship in The Weakness Of Beatrice The Level Cap Holy Swordswoman is between the human Beatrice and the orc Boo Boo. While Beatrice also has some degree of enhanced strength and toughness, Boo Boo is vastly stronger than her. Though they've yet to actually do anything intimate, since Boo Boo is a Chaste Hero.
- They got around this in Lois & Clark by saying that part of Clark's powers were that his body emitted a kind of "invulnerability field" which extended a few millimeters from his skin but could also affect anything he touched or kept in close proximity(*snicker*), giving it the same durability as Clark himself. Also explained how he could pick up things weighing several tons without just ripping two handfuls of material out of them.
- Note that the couple did consummate their marriage, in the episode immediately after the wedding (There was an issue with Lois dying as a consequence, but that was because of a curse and not because of Clark's powers).
- The issue of being able to have children only first comes up in a scene where Lois and Clark's dialogue suggests that they have been taking actions to prevent the creation of a pregnancy, but in this last interchange did not. It is possible though that Dr. Klein is worried about this issue, and since he is so totally clueless as to not clue into a married women who obviously loves her husband being disturbed by the news that Superman ages much slower than human beings, it seems hard to believe that he is being subtle in his later admonitions to Superman about taking precautions.
- Also, in the episode where Clark loses fine muscle control due to Red Kryptonite exposure, there is a scene where he sees a bruise he accidentally gave Lois, and decides separate bedrooms would be safer for now.
- Smallville's version of Clark has the typical problem with his first love interest Lana Lang. The problem is eventually resolved when Clark is de-powered for an episode, but when his powers return, he actually complains to Chloe about his sex life. By the end of the show's run, he has gained enough control over his abilities that the problem no longer exists. He outright states that his training at the Fortress of Solitude included learning exactly that sort of control. Apparently Jor-El never expected his son to remain a virgin for life.
- Notably, while Clark is complaining to Chloe that, after finally having reached "the next level" with Lana, he can't keep it up for fear of hurting her, Chloe wonders what the big deal is, since they can shake hands and hug without Clark pulverizing her. Clark explains, rather embarrassed, that it always takes him some time to adjust his "abilities" to new circumstances. Chloe decides to cruise right past that mental image.
- Discussed in Season 4 of Buffy the Vampire Slayer, where, during a fight with Spike, he taunts Buffy about a recent sexual encounter of hers (which ended badly) by saying "Were you too strong? Did you bruise the boy?"
- Somehow got around in the Doctor Who story "Dragonfire". The villain Kane is a ultra-low-temperature humanoid, whose ungloved touch can freeze a human to death in seconds, and even touching an object he's just handled can cause horrific freeze burns. Nevertheless, he is strongly implied to have had a past sexual relationship with his Dragon Belazs, who is apparently an ordinary human (or Human Alien). Since Doctor Who at the time was fairly prudish, precisely how this worked is not even hinted at.
- This is a concern for Worf, a Klingon, in Star Trek: The Next Generation. When asked in early seasons about the prospects for his love life, he replies that he would require a Klingon woman as human women are too fragile. Subverted: while Klingons do have greater average strength and durability than humans and a penchant for consensual rough sex, his concerns turn out to be exaggerated. There are at least two confirmed Klingon-human pairings in-universe that result in a child, and Worf himself later dates and is intimate with a half-human half-Betazed woman and two (physically) different Trill, all three of whom are roughly equivalent to humans. It's strongly implied that Worf was merely using this trope as an excuse to avoid dealing with his intimacy issues.
- In the The Almighty Johnsons episode "Hunting Reindeer On Slippery Rocks", Ty Johnson, avatar of the Norse god Höðr with Power Incontinence, is pursuing a relationship with Dawn, a mortal woman, without telling her about his powers. His grandfather Olaf grills him about the extensive precautions he's taking to avoid accidentally killing her. Later on, Ty's precautions prove inadequate, and Dawn nearly dies.
- In one ending joke in The Vicar of Dibley, Superman inadvertently rapes the Invisible Man and the Invisible Man says "It hurt a lot."
- Jessica Jones (2015): Subverted. When Jessica and Luke have sex in the first episode, they're both clearly worried about killing the other, since they both have Super Strength and Super Toughness, but don't know the other one does. When they find out about each others' powers in a later episode, they're able to try again.
- Supergirl (2015):
- Lampshaded by a shock jock in season one.
Leslie Willis: You know, who's hombre enough to puncture the Chastity Belt of Steel?
- Confirmed in season 2 when Kara admits she broke four guys' noses just by kissing them. She's happy to be finally dating someone at her strength level — Mon-El.
- When Lois announces that she's pregnant with Clark's child in the Elseworlds crossover, she explains that she and Clark plan to spend the pregnancy on Argo, where the baby won't have any powers and thus it kicking won't cause any harm. It's also heavily implied that their previous visit to Argo is how the pregnancy came to be in the first place.
- Lampshaded by a shock jock in season one.
- A minor example from Mass Effect 2: Female Shepard can romance and have sex with Garrus, a turian squad member. Turians are an alien species adapted to a much harsher world than humans, leading to such lovely features as razor-sharp teeth and pointy bones protruding out of their skin. When the crew doctor, Prof. Mordin, catches wind of this, he immediately offers helpful advice on "positions comfortable for both species", as well as "oils and ointments to reduce discomfort". (It might help that Shepard is at this point a cyborg with bullet-resistant skin and nearly unbreakable bones.) He also cautions that there are certain amino acids that don't play nice, and warns her not to "ingest".
- Also, Male Shepard's romance with Tali, a quarian (species with atrophied immune system), who has to pump herself with immuno-stimulants to even be able to touch Shepard. Interestingly, in both cases, it's the woman who is endangered by contact.
- And there is also advice about dealing with accidental telekinesis if one with such talent is involved in the romance.
- And then there's Fem!Shep flirting with Joker in Mass Effect 3. Joker proceeds to lampshade the trope immediately (unlike the other examples, Joker's the one in danger thanks to his very fragile bones and Fem!Shep, once again, being a super-strong Cyborg).
- Party banter between Sten and Morrigan in Dragon Age: Origins suggests that Qunari have sex so dangerous that a human would have to wear a suit or armor and have something to keep between their teeth (like a bone). He's probably exaggerating for the sake of messing with her. Iron Bull, a Qunari love interest in Dragon Age: Inquisition, is mindful of the risk of damaging his partners during sex, but that's just from being seven feet tall and very heavy along with the dom/sub dynamic he prefers, not from Sten's claims being true.
- World of Warcraft: Deathwing cannot mate with any other dragons due to his corrupted body being made of molten lava. The only survivor, Sinestra, was left horribly mutilated. He had also apparently planned to kill Alexstrasza and Ysera this way after destroying the world.
- Referenced in a strip of It's Walky!, although it's more a case of straight-up Destructo-Nookie.
Hotel employee: Man of steel, woman of Kleenex?
Angry hotel manager: No! Man of steel, woman of steel, bed of Kleenex.
- Oglaf has a story about the Snow Queen, spirit of winter, who needs to be sexually satisfied or spring is not going to happen. Let's just say that even the most hot-blooded of men cannot take her freezing qualities and return home in one piece. It gets better though, when a clever adventuress happens by. With her trusty strap-on.
- Gender flipped with Yuki and Kobayashi in MegaTokyo, though it's less about sex and more about teleporting all over the city (however, the former is the first explanation Komugiko thinks about when she sees them).
- In a Palcomix comic called "Greenheat", the Martian Manhunter, while in heat, seduces several women, including Lois Lane, under the guise of their boyfriends. Afterwards, they catch him and reveal they knew all along. When he asks how they knew, Lois states that the real Superman never dares to be the active partner during sex.
- Saturday Morning Breakfast Cereal has Superman turning down a potential love interest by citing this trope, who regretfully accepts the reality of it. The man Wonder Woman used the same logic with? Not so much. The bonus panel reveals that the man was the author stand-in, and only lasted two minutes.
- One strip of Loserz had Jodi pondering how awkward it must have been for teenage Superman to have sex, especially if the girl wanted to get spanked - leading to Superman covered in Ludicrous Gibs and a news headline the next day about "Mysterious ass explosions!"
- Alison (the strong female protagonist of Strong Female Protagonist) worries about the WoS/MoK aspect of this, and consequentially has trouble getting physically intimate with anyone. Her government-appointed doctor points out that since she doesn't destroy her bed whenever she tosses and turns in her sleep, she shouldn't have a similar problem with any other...autonomic reflexes.
- A downplayed version is seen at one point in Ménage à 3 where DiDi is seen laying in bed with an expression of post-orgasmic bliss while Kiley is sitting up visibly wondering if permanent damage has been done to her hand.
- The Russian comic Dumbest Mage Ever (translation of the corresponding parts here - warning, gory) has a hobbit girl using a love potion to seduce the Dumb Muscle protagonist. After the second time she goes "Pop", him and his mentor decide resurrecting her isn't worth it.
- Plumbing the Death Star:
- In "Which Superhero is the Best Lover?", Duscher argues the Incredible Hulk would make a great lover and gets laughed off by the rest of the cast when they realize that coitus with Hulk would definitely end with him accidentally ripping you to shreds from sheer strength.
- The central issue in "Why Doesn't Rogue Use Protection?" is Rogue's inability to have sex due to her mutant powers, though the discussion veers into the problems most of the mutant population and the Fantastic Four must have with sex. They conclude that Iron Man and Reed Richards, with their ridiculous intellect, could simply make de-powering collars or full-body suits to prevent superpowers from interfering with coitus.
- Mentioned in Interviewing Leather as one of the reasons why Leather only has other Supers as boyfriends.
- Expressly discussed in the Whateley Universe, particularly in "Sara's Little Purple Book" (NSFW), which explains how to deal with sex when you're a PK brick or a lightning Energizer or any of a couple dozen other types of powered being. Sara is a Goddess of Lust in the making, so it make sense that she'd have a certain insight into the matter. Unlike many others, she deals as much with the 'Woman of Steel, Man of Kleenex' issues just as much as the reverse, as well as questions of how different powers interact. While the book is mostly about Power Perversion Potential, nearly half the discussion is on the dangers involved and how to avoid them.
- In The Jenkinsverse, humans are substantially stronger and tougher than all alien species. While the principal barrier to interspecies sex is that nonhumans just aren't interested, if any of them were then the inevitable result would be serious injury or death.
- In If the Emperor Had a Text-to-Speech Device, most of Emperor's mortal partners either suffered explosive orgasms or were left with broken ribs and in generally bad shape. As a matter of fact, he didn't know that any of them survived, much less borne him children.
- In Anime Marriage Prospects, this was mentioned as a potential hazard of a relationship with A-Ko/Eiko Magami (for all practical purposes the daughter of Superman and Wonder Woman).
- Woman of Steel example: Upon visiting a planet of eight-foot-tall, super-strong Amazons, the heroes of Futurama learn that the men of the planet died out from crushed pelvises. The male characters are alternately intrigued and horrified when presented with the sentence of "death by snu-snu". Fry and Zapp Brannigan manage to survive — they end the episode in full-body casts, but don't mind all that much.
- Intermittently discussed in the fourth and fifth seasons of Adventure Time, as Finn struggles with the obvious practical problems of a human in love with a fire elemental—and the danger works both ways, since as far as Flame Princess is concerned Finn may as well be made of water AND sufficiently strong emotions makes FP lose control of her powers to such a degree that it would endanger the earth.
- One gag with Superman on Family Guy has him and two police officers investigating the death of a woman, who's lying on the bed in a nightgown with her brains literally blown out across the headboard. According to Superman, he just got there and has absolutely no idea what could have happened, just like the three men in the public washroom.
- A Robot Chicken sketch had Superman accidentally blow Lois's brains out from the power of his...ahem, load, while she was giving him a blowjob. Cue baffled policemen wondering where the gun, bullet holes, or gunpowder residue was, before theorizing that Lois may have gotten killed from giving Thor a handjob.
Clark Kent: That cheating bitch! She blew me in that chair just last night! [realizes what he said] Uh, I mean...yoink! [runs through wall to escape]
