It's OK. 20 is not an old age to start. Being on HRT for more than 6 months will bring great, unreversable change, according to the experience from other MtFs I know.(I haven't started HRT) And, please, go to a doctor or therapist for advice. Don't buy the medicine by yourself. BTW: I am Chinese. English is not my first language, but you can always try to use something like Google Translate to have better communication.
