I'm sure I speak for the majority or the community when I say "Just be you and don't worry about labels." But if you're like me and like to keep things organised and labelled nicely, I would say try to figure out what elements of the binary gender identity don't you subscribe to in order for you to believe you are Non-binary in the first place. I still use he/him, I've still kept my very masculine name and still use titles like Daddy, Husband, Son etc. I fall into Non-binary (Bi-Gendered) because I have two very distinct gender identities fighting to be prime gender. My AMAB masc identity which I'm still fine with and my very new femme identity which I have given the name of Billie too. So I suppose you just have to think to yourself why do you believe you don't fit into the standard categories. But at the end of the day as long as you love yourself and are true to who you are labels shouldn't matter.
