The appointment was rather funny tbh. The lady asked me “so what gender should it be?” when filling out the form.
Then she explained to me that if a war breaks out, I won’t get enlisted even after the name/gender change cause apparently I’m still a woman.
Also, if I happened to birth a child, I’d legally be their mother and they’d use my deadname. So apparently you can be two genders at once in Germany if you play your cards right.
I even have my second appointment in November already, I know where to go and what to bring and what happens then. Now I just have to convince my parents to give me my birth certificate.
