YOU ARE WRONG!.. hormones do cause someone to have a natural chest, being that my sister is a transgender, you do NOT need 4 years of therapy unless you want surgery to remove the penis. Transgenders usually only have their cheeks pumped, and chest grown out and pumped as well as having hips, thighs and ass pumped with silicone... she could infact be a man, being that my sister whos a transgender is COMPLETELY UNCLOCKABLE, even by doctors
