Thanks everyone for their input! I kind of thought my Dr. didn't know what he was talking about. I know testosterone thickens the vocal cords so it shouldn't matter how old you are if you were born female. The vocal cords would be thin, so thickening would happen. Maybe he's confused and was thinking about MTF. Anyway, I had a personal message on here but it won't allow me to reply so I'm not ignoring you, tjack77, I just can't send a personal message but I'm super excited to hear from someone close to my age and know that it is possible to have a deep voice at my age!
