Work Text:
Tony Stark:
- He's insecure that he has too many bitches. With his good looks, women swarm to him like bees to flowers, and he's worries that having ladies constantly hit on him would make you not want to have a relationship with him
Bruce Banner:
- He's self-conscious about his lack of ass. When he first transformed into the Hulk, his ass area did not rip, and that made him cry for days
Steve Rogers:
- His dick being too big. He's worried that if his cock is too huge, it can't fit into you or anyone else. However, you prove him wrong ;)
Clit Barton:
- His bad taste in fashion. I mean, who the fuck wears sleeveless shit anymore? You buy him some better clothes
Thanos:
- Tony made fun of his feet by calling them "smelly and hairy" and now Thanos never shows his feet to anyone, and religiously washes them and perfumes them so that they small like flowers
Bucky Barnes:
- His metal arm. You make him feel better about it by reminding him that it will never get tired when he decides to stroke his dick for multiple hours
Scott Lang:
- His wife divorcing him left a hole in his heart. Luckily, he feels much happier with you then he ever did with Maggie
Peter Quill:
- His dead mom that Rocket keeps on bullying him for
Rocket Raccoon:
- The fact that he always has fleas, but you solved the problem once you put a flea collar on him. Though it was embarassing for Rocket; he felt relief when his skin didn't feel itchy anymore
Natasha Romanov:
- She can never bear children, but you reassure her by adopting some dogs and cats
Pietro Maximoff:
- The fact that there's nothing remarkable about him at all. Even Wanda calls him "bootleg Flash"
Wanda Maxmioff:
- Rocket bullied her for being a "soulless ginger." You tell her that her hair is very beautiful (both the carpet and the drapes ;)
Thor:
- For being to muscly. He's worried that he might accidentally squeeze you with his big, bulky biceps while you're cuddling
Loki:
- He was born different from the rest of the citizens of Asgard, and that always haunted him. You comfort him by making him always feel at home when he's with you
Pepper Potts:
- The fact that she mostly keeps to herself and doesn't have that many friends. You help her by keeping her company (in more ways than one ;)
Sam Wilson:
- The fact that all the Avengers have cool powers and he has a fucking bird suit. You remind him that Ant-Man has a worse animal and that Barton has no superpowers
Nick Fury:
- Nothing. He is a god. Well, maybe just the fact that he gets very angry when he plays Call of Duty and he loses against a bunch of ten-year-olds
Stephen Strange:
- The fact that he's a broke boy. You urge him to start a crypto scam
Bonus:
Eddie Brock and Venom:
- Eddie is insecure that he can never be a player like Venom. And Venom is insecure about absolutely nothing because he is a stunner
