I think of medical and surgical transitioning as being a bit like being an immigrant. I remember, when I was in my first year at university, there was a guy in one of my classes who had a Greek father. His grandparents had emigrated with his father when he was an infant and they had a hard life. He said that his father had lived here most of his life, but he still liked a good feed of olives and bread, he still hated Turkish people because of the Ottoman Empire, and a few other things. A person who transitions whether they transitioned last week or 40 years ago, can still like things from their old life. Transitioning from male to female or vice versa does not mean that you have to completely change your tastes.

My own non-binary status is like this. My gender is fluid. I have a male side and a female side, and I celebrate them both. My female side is more dominant, but it doesn't mean that I'm a male when it suits me and a female when it suits me.
