Also, imagine the aftercare! Of course, all Steve wants to do is hold Bucky's hand, rub Bucky's back when he's recovering from a nightmare, massage Bucky's prosthetic joint when it hurts him, but now he CAN'T because every gentle touch just reminds Bucky of when Rumlow would do the exact same thing. Steve can't even help Bucky recover like he wants to, when Bucky flinches away from any "loving" contact.
