Hi @lispey.
If you are seriously considering a bilateral mastectomy, could I suggest you take advantage of the bulk billed counseling services that you can access via your GP (who can do a mental health plan without any fuss) Breast care nurses can then help you find someone who will suit you.
The rationale behind this is that you get to talk through the issue then, if you are sure it's right for you, when you find a surgeon you can demonstrate that you are aware of the implications of what you are asking. Going public should also not be an issue unless you are in a small centre where ideas about this procedure can be a bit backward. I had to interview 4 surgeons defore I found one who would do what I wanted and when but that was a while ago and attitudes are changing.
I don't know where you live but if you are in Victoria I'd ask for a referral to Peter Mac, you will find someone sympathetic there.
Health care can be like any other service, sometimes you have to do a bit of shopping. Marg
