I have a headcanon that bucky is really touchy ans cuddly with people he trusts 100% (sam) and absolutely avoids touch with those he doesn't trust 100% (the rest of the world)
So while u see bucky avoid touch like it's the black plague, when u see him with sam he becomes the most touch starved person (and I feel like he is, bc maybe before everything he did like to hug and to cuddle his family) he be following sam like a puppy just to get a hug, they have to kiss good night and good morning, kiss goodbye and hello, and all this demands by bucky.
And sam really really loves it. He loves bucky curling his huge body into sam when they are in the couch, loves when bucky demands a hug and when they hold hands. Best thing?? Bucky is the little spoon in bed and sam is living for it.
