When I first realized thst was trans I had no real interest in changing my presentation. I wanted hormones only for the mental effects. As time went on I began to desire the physical feminization as much as the stabilizing effects of running my brain on estrogen. Ultimately I changed​ my presentation, my documentation, almost everything. I feel no need for GRS beyond my fear of being in a nursing home with mismatched genitals and my irritation with a nearly non-functional penis being in the way.
My point is that, as I've changed, my needs and wants have evolved too. I'm on a long journey and none of us can be entirely sure where that journey will take us
