I advise clients to put ... common useage, want name to reflect self, safety (if they ask that a man with a female name causes you to get into violent situations), ...etc...doesn't really matter - they just want you to say something so if you are doing it for criminal reasons they have another charge against you. Most judges really don't look at it.
I don't know what state you live in .. but lots of states will now allow for you to state you want your birth certificate gender changed as well if you bring a letter from your doctor or therapist.
