Bucky Barnes/Steve Rogers Preferences

PDA

Steve Rogers:

Steve has always been very shy when it comes to showing affection. In public its really just hand-holding and side-hugs, but with friends he'll hold you and share an occasional peck on the lips.

Bucky Barnes:

Bucky is constantly holding your hand, just to be sure you're real. It helps keep him grounded when upset. When around friends he's constantly showering you in affection, often being told to get a room.

Soo I was thinking of kinda giving the reader a sort of backstory??? Like weaving the reader into the marvel world. It may take a while to put up and write because I want them all to make sense but I would like to try.
