@alyeska part of why I didn't try to get an X was that I didn't want even more unwanted attention when traveling to the US, but now going there would be a bad idea anyway.

I don't really care about what's in my documents anymore, as long as it never gets changed to M. The name I get called most often is different from my legal name, which is different from my previous legal name. Identity is more fluid than documents can ever be, and it's not as if showing my passport would stop anyone misgendering me.

Maybe if enough people had an X it would help convince organizations to address them with nonbinary words. Personally I don't even want that anymore, because I feel nonbinary gets misunderstood by cis people as a single gender that gets policed even more than woman. Instead of giving freedom from boxes, an X would place me in an even smaller box.

All that said, if you have the money, do what feels right. Being a bit happier for the rest of your life is worth a lot.
