Fandom's willingness to conflate actor and role strikes again. Chris Evans is a very enthusiastic Dog Dad.

Also, well, fandom's view of Cap is not necessarily what's on the screen in general. He's not naive or simple or an old fuddy-duddy and he's heard of blow-jobs (and probably gotten a few) and yet here we are with how many Virgin!Steve fics where the poor guy's never seen naked boobs and can't get pop culture references... they want him to be a golden retriever, so he is. Just like they want Tony to be a woobie.
