I think what would be interesting is that if Bucky on some level knows he's safe and no longer with the bad guys, and that realistically he knows no-one will intentionally hurt him...but the conditioning is just stronger.

And then maybe, just maybe he gets into a fight with Steve or whoever he's with, and they have make-up sex, but it's sort of primal and feverish - and it HURTS Bucky, but he doesn't make it stop, because despite knowing better, his conditioning tells him it's supposed to be like that.
