Inspired by this dorky exchange I had, thank u BountifulEggnog.
I want to know what your gender means to you, how you define it, what it means for you to "be" that gender and how you define it. Don't fuss about 'correct definitions' or anything, this is about your experience, I want to know what it means to you. How you relate to that gender, perceive it.
Genders have a social construction aspect and is very subjective, so I think people's subjective, personal views of their own are both important and interesting. Inquiring mind wants to know! 
I'll share some of mine I guess.
I was a trans woman until the contradictions sharpened to a razor's edge after reading Gender Outlaw and The Gender Accelerationist Manifesto. My brain got cracked in half. I have always hated the effects testosterone would have on my body, so estrogen was a given, but while I do identify with certain things that are commonly associated with being a woman... if nothing is inherently gendered, what even is a gender? 
I had a whole little episode about it in the megathread once.
As I went on from there, I realised that while I like certain things about "being a woman", equally I found I'd been sort of stifled by trying to fit into the social role. The women I have always related to most are the cis autistic women who basically yeet presentation in favour of dressing for sensory comfort. Almost kinda non binary, in a way... The more I interrogated binary gender in relation to myself, the more I dug up stuff like this. Also I didn't really like that "woman" is associated with cis people a lot, I really like the trans part of my identity, feel a lot of love for it. I've felt freer and mentally clearer and truer to myself as a Non Binary Transfem, it's cool and funny. What does it mean to me? It represents my goofy sometimes-androgynous presentation, my lack of cissie gender, how being neurodiverse influences my view, being a funny noody goblin. Share yours =)
this is my answer to the question. that's all it is to me. i was just telling someone how like, being always taken in by the women & being mocked by the guys kinda eventually led me to this situation where i'm owning all the vile garbage from my past, but also the affirmation of the ladyfolk. if you want a label, non-binary woman makes the most sense to me. i'm so over labels, though. just. Gender Chaotic.
be confused, cissies; be afraid of the feelings you have perceiving me.
something i have been feeling lately. us just, existing. in a public space, with our own bodies. often feels like gender warfare. people are going to perceive us, react to us, struggle with their own concepts of gender because we don't fit into them. and that can be dangerous, yeah. it's no fucking wonder we venture into the outside world so rarely. but just existing, and excercising control over our own bodies, is a fuck you to them. and i'm proud of that i guess.
and that means far more to me than a label - though i don't begrudge anyone who finds labels comforting or useful.
