I think it would help to just spell it out that you will correct them based on how you feel. Because if they can not feel chastised when you tell them that your pronouns are actually whatever they are. Then they could probably keep adjusting quickly. That's not exactly what I do, but it's similar enough that I get it. Here's what I do, I prefer different pronouns situationally, based on relationship with the speaker. So It's she/her with close friends, He/him with my wife, and I genuinely don't care with strangers. Does anyone else here do that?
