Last year I legally changed my name from Amy Caren to Jamie Ray. If you have changed your name you know it is a complicated thing to do, socially and legally. Once you get the court order, you have to change all of your paperwork. All of it. And I didn’t want to keep seeing mail with my old name on it.
When I changed my name I kept my sex marker at F. This irks me, because if I could, I would set it to N/A, or N/F, or ∏, or Q. Something more descriptive than F. I could handle two markers, one for sex (Female) and one for gender (Butch, Queer, or Trans*). It would be more honest.
