It’s tricky even asking. I have one androgynous-looking co-worker. I asked the person “What’s your preferred pronoun.” They didn’t understand what I was asking. After two weeks, I found out that they preferred “she”.
If there is any confusion about your gender or name, it’s up to you to correct and inform the person misgendering you. I know that gets tiring. People judge the book by the cover more then we like to admit.
I think the thing that everybody needs to remember is just be respectful. Apologize when you make a mistake. It’s also our responsibility as a transgender person not to be mean to someone when they make a mistake with you. Again, it’s get tiring having to take the high road all the time. It will pay off later on.
