I believe lousyd and dingus said almost everything I came in here to say.
Growing up I never felt like one of the "boys". It felt like even in prepubescence there was an expectation for boys to act a certain way, but I never fit that mould.
Whilst I enjoyed boyish things like playing football, when it came to the social side of things I always preferred talking to girls and indulging in their activities (at that age, it was silly things like making daisy chains and stuff).
Thankfully, my parents taught me from a very young age that society has its problems, but that society should never hold power over how I express myself: always be kind, never hurt anyone, but don't take people's shit either.
Through adolescence I would also do many things that most people wouldn't consider "normal" or "manly". On the rare occasion I'd play with my sister's Barbie dolls, I kept a diary (which I only ever really saw as being a 'girly' thing thanks to mainstream media), but it never even occurred to me that doing all this stuff made me anything other than a "boy".
Society wants to put labels on everything to make shit really digestible, but finding a label to put on yourself may not be any kind of magical mystery cure to the uncertainty you may feel about your gender.
The problem with labels in general is that once you have one, it creates an internal dissonance if you don't conform to the norms of that label. "Why aren't I like other girls?" is a perfectly valid question when society has told you in no uncertain terms what a girl should be, and then realising you don't fit that stereotype, but you could replace 'girl' with any other label in that question and still find yourself at odds with societal norms.
In the end I'm just "me", and you are you, and whilst this feels like it goes against the grain of society at present: understanding that you don't need to add labels to yourself can bring your own sense of inner peace.
If someone asks you "Oh, are you non-binary?", "Are you asexual?", "Are you [whatever]?", it can be rather liberating to be able to say "dunno, don't care, if that's what you wanna call me, you do you" or words to that effect.
tl,dr; fuck society, you do you ❤️
