Let's exploit the vague nature of Bucky's serum and say he actually can catch diseases. So, during a Hydra rape, he caught an incurable STD.

I am up for any kind of STD trash, including Hydra shaming him, reactions from his other rapists, and uncomfortable physical symptoms -- but especially anything that focuses on or includes aftermath would be great. Like Bucky being too ashamed to seek/suffering through medical treatment, or the agony of disclosing his disease (and thus his history of rape) to his sexual partner(s).
