^ yea what she said.
Remember that HRT may not be your solution and aid in transitioning. So far it hasn't for me but it has made me more comfortable or might I say feel "right".- these are mental changes.
Do I pass yet? no
Does it mean I'm not a women? no, I just haven't developed the the social skills that learned through nurture not nature.
Well physical changes varies. Genetics and age play factors along with smoking, drinking, stress and many other things.
Some people were "forced" to go fulltime after HRT- that really depends actaully. Some can go 2 years on HRT and still pass as males. Others need to go fulltime.
I suggest you make sure you have a good endo. Because the amount of success is also determined by your doctor. Many doctors prescribe menopasual doses and have no or little TS experience. However all doctors I think start with a lower dose because some people need a lower dose.
Other than that don't think HRT will magically transform you, it takes some effort on your part too to live and be accepted as a women.
HRT for me is going "okay" so far but it's only been 6 months and HRt works at different rates.
GOOD LUCK hon
