Disney may own Marvel these days, but graphic Marvel sex still has a whole history that would make Walt blush...or possibly claw his eyes out. It only makes sense that if superheroes with perfect physiques existed, they'd have sex with each other, and Marvel's whole thing is that it deals with real-life problems for its characters.
Sex causes problems, true, but the way sex scenes in Marvel comics depict doing the nasty sometimes is a problem in itself, often playing intimacy for shock value, or creating what is effectively licensed fan fiction. The reader, in the end, must be the judge.
Here are the most particularly vivid scenes of graphic Marvel sex. Be forewarned: not all are consensual, and even those that are can get unpleasant in other ways and may be NSFW.
Tony Stark and Black Widow Make a Sex Tape
Okay, to be fair, they didn't intend to make a sex tape. The security system was hacked. But that's not the disturbing part.
The disturbing part is that Natasha appears not to have nipples. No wonder she betrayed the team - Tony probably pointed that fact out and it made her angry, or something. Hey, that makes as much sense as anything else in The Ultimates.
Ant-Man IN the Wasp
While everyone wonders about certain superheroes in the sack (stretchy Mr. Fantastic, for example), Hank Pym actually went there, using his shrinking powers to go all the way inside girlfriend Janet Van Dyne, before coming out dripping with moisture. Because Avengers #71 got a rare "mature" rating as a result, there was some controversy, but fans complained just as much about the overall artwork and story as they did about excess Wasp-juice.
Now that Disney owns Marvel, and Ant-Man's a family-friendly movie character (and not even Hank Pym any more), he'll presumably stay much drier.
Wolverine and Magneto's Wife
In the Ultimate universe, Magneto had a wife conveniently named Magda, but before they were married, she took in an injured Wolverine and they engaged in a little coitus interruptus, casting some doubt later on the true parentage of Scarlet Witch and Quicksilver.
It gets better, in a terrible way: Quicksilver and Scarlet Witch in this universe are into incest... and Wolverine spies on them doing it. Sometimes he's actually the worst there is at what he does.
Deadpool Does It in a Coffin
This one might be the most normal one on the list. Just a married man having sexual intercourse with his wife.
Except he's an immortal tumor mutant, she's a shape-shifting monster, and they're doing it in a coffin after she just punched a hole through another guy's chest.
At least in the movie, Ryan Reynolds's sex scenes all happened pre-mutation.
Public Hulk Sex
In Incredible Hulk #7.1, Hulk and alter-ego Bruce Banner have been separated, and Hulk doesn't quite know what to do when he's not angry.
So he has sex with Red She-Hulk in public, of course. Like you would if you were the Hulk.
Don't worry, though; it's not incest. She's Betty Ross. Hulk doesn't f*ck his cousin until the alternate future of Old Man Logan, in which they have inbred hillbilly babies.
7 people just voted on He's the Juggernaut, B*tch
The picture says it all. This one didn't technically happen in comics canon, but the picture is amazing. She Hulk and Juggernaut ruined pretty much the entire room.
You may know Jessica Jones's name from the Netflix series of the same name. You may not know that in the Alias comics, she engaged in anal sex with Luke Cage. The combo of anal and interracial was too much for Marvel printers in Alabama, who initially refused to print the comic.
Jessica and Luke still got it on in the Netflix series, but in a much more traditional position. But they'll interact again in Defenders, so there's still a chance for backside boning.
7 people just voted on Meat & Mystique
What's more of a heterosexual alpha-male fantasy than getting between the sheets with shape-shifting beauty Mystique?
Doing it while eating a bloody, raw hunk of meat, of course. That's Sabretooth for ya.
Bleeding Cool called it "THE single worst-written scene in the entire X-men line this year." Teenage boys undoubtedly called it "boner fuel."
