If you live in the U.S (and canada, i think) you need to find a "gender therapist" for a minimum of..i think 3 months to get a recommendation to an endocrinologist and be prescribed hormones (usually spiro/estridol from what i've heard, but I don't know)
Most (not all) go through voice training and electrolysis.
umm.
you'll probably need new clothes and things, and to find a job that will allow you to present as female at work (and not be discriminatory)..
and, I think (at least in my area) that you need to be on hormones for...2 years (it's either hormones or therapy that you need 2 years of) before you can get bottom surgery.
oh, and the hormones will cause breast growth, but if you're not satisfied with your breast size then you'll need to talk to a surgeon about implants.
