Hi there Lisa, big welcome to Susan's...
First up, no 37 is not to old, I started at 50, still in progress now!
You are lucky having a feminine body shape up front, and, minimumal hair growth. Kinda agree with LordKAT on the herbals, I tried that for many years until I went on HRT, but any hormonal changes are heavily influenced by your endocrine system and genes etc.
Not sure if you are in contact or seeing a Gender therapist / counsellor but may be worth while, especially given your plans in the future.
Anyway welcome and look forward to seeing you about the forum's...
L Katy
