I have had a difficult time in having those around me gender me properly. Sadly, it is only those who I know and actually care about that struggle. It appears as though to everyone who does not know my past, that I pass wonderfully. However for family, friends, and coworkers what I frequently here is "I'm sorry, it's just that I knew you as a man for so long, it is really hard for me to gender you properly now."
So...... recently I told them all, stop thinking of me as ever existing as a male, as I never have been. Even though I may have been presenting differently than I am now, I have always been female. Thus I asked them to try and "lie" for me, and always refer to me as having been female for my entire life. I only quote lie as it appears to be a lie for them, but not for me as I understand my truth. Being as I asked that of them, I expect the same for myself and I have begun referring to myself as having grown up female.
