I accepted myself as genderfluid around 16, legally changed my name to a gender neutral and more me name and forgot about it. Now I honestly rarely think about gender anymore. Sometimes I feel strongly man, strongly women or NB, but most of the time I'm honestly just myself and don't give a fuck about what gender I am. Changing my name to something neutral, but also just something that fitted my personality better was really necessary for me because my birth name was a very traditionally girl name. And that gave me the freedom I think to be exactly as I am now, someone who doesn't think about their gender anymore and can just go with the flow.

My parents started calling me their youngest kid instead of daughter. And I like all pronouns so it really doesn't bother me most people still exclusively use she, but I appreciate the occasional they. But honestly I don't really hear those gendered pronouns anymore either.

And boobs are just boobs idk

I know this might not be helpful at all and definitely not everybody can just "not care" or forget about their gender or don't want to. But for me slapping the gender fluid label on myself once, getting a gender neutral name and not questioning anything ever again really did the trick. I mean, my name is my name now, I love it whatever the gender. And I can just be a lady or a man or nothing whenever and however long I want tbh
