Avengers Preferences and Imagines

What you find most attractive (physical)

Tony Stark:
His smirk.
When he makes a joke and waits for a reaction from people, he has that little smirk on his face that makes you want to kiss him or slap him depending on who you are around.

Steve Rogers:
His muscles especially when they are flexed.
The serum helped him get nice muscles and he works out a lot, allowing him to have even nicer muscles. You like watching him while he works out because he is so strong and he flexes his muscles. This shows how defined and nicely built he is and that you are the one who is dating him.

Bruce Banner:
His hair.
You love to run your fingers through his curls. It helps calm him down when he is stressed and prevents him from hulking out.

Clint Barton:
His arms.
He has nice biceps from all of his agent work he has to do and when he his working on his archery skills, he likes to show off both his arms and his abilities to you. He is much stronger than you expected when you first met him.

Thor:
His beard.
You like how his beard helps give him a rugged look. It makes him blend in a little better, but other than that, he sticks out in public. It also tickles you slightly when he kisses you on the cheek.

Loki:
His smile.
He doesn't smile much but when he does, it makes butterflies flutter in your stomach. It makes you happy that you are one of the few reasons why he smiles and will try to make him smile as much as you can.

Pietro Maximoff:
His abs.
You love to look at his abs when he takes his shirt off and you also don't mind putting your hands on them. He knows you like his abs so sometimes he will just walk around shirtless so you will stare at him.

Bucky Barnes:
His eyes.
You could stare into those grayish blue pools for hours. They are also calming to look into and they can show his emotions that he may not be able to explain or show in other ways.
