I personally advocate the Informed Consent path....
...meaning, I feel that adults should be able to make adult decisions about their lives and bodies. Thankfully, there are many doctors, therapists, and others who agree with this. You may want to research "ICATH" and "Informed Consent"...there are lists of doctors and resources that you can use, and therapists that will give you letters that you can use for reputable surgeons.
That said, while I support anyone's right to make these decisions...it is not always wise. Personally, I feel that a couple of years of HRT, and living full time is simply the smart way to go. Your body will change a lot during HRT, and things will move and settle in various ways.
For the same reason that many suggest waiting until after a couple of years of HRT to have breast augmentation surgery, it may be a good idea to wait for SRS until the body has had a chance to do it's thing.
However, we each have our own path. And I support our right to find it, and walk it.
And, I am fond of saying...I could go have my entire body tattooed green, my tongue cut in half, have horns surgically implanted into my head, and call myself a lizard....with no therapist letters, no RLE, nothing but my own judgement and money. We are who we are, and I cannot think of any reason at all why we should be singled out and treated as mental patients for simply wanting to live life as a whole person.
