I don't know what you mean by frustrating. For a Black Mirror episode, it had such a happy ending!
Yeah, maybe I've spent too much time on r/sex and r/relationships. The answer is always communication! It's just surprising to me that someone could be in a relationship for 10+ years and not communicate everything, no matter how embarrassing or intimate.
First thing that popped in my head when I read the headline. Really liked the episode.
