I am so lucky that my employer has a special leave of 4 weeks at full pay for recovery from Genital Surgery, and I planned to be off work for 6 weeks, so my manager needed to backfill my position. So my doctors, my family, my employer and my trans groups all knew when I was having surgery. My government health records have my transgender status listed, as well as my surgery (this is optional in my country), and I agreed to that in case I needed medical attention away from my home.
Outside of this, I do not readily disclose my surgery to anyone else, except for a couple of close friends. I am openly trans as my community is supportive, and most people can guess anyway, but what is in my panties is my business. I had a man attempting to have a relationship with him, and I told him I was trans, then his next question was did I have the surgery, but I did not feel a need to answer him, especially as I was discouraging his advances. If I was ever lucky enough to find someone to share my life with, I would be open with them, as I have been with all my partners.
Like Victoria, I haven't disclosed my status to my dentist as I don't believe he needs to know, though he was my dentist for decades before my transition, so I imagine he suspects.
Hugs,
Allie
