When can you call yourself Non Binary?
To be quite frank I haven't done much research on this topic. I'm a biological male and went as a boy all my life so far. My question is kind of odd, like am I allowed to call myself Non Binary? Or would I just be invalidating real experiences from other people?
It's just that I personally don't like considering myself a man (I'm okay with boy or dude, but man feels off for me) (and I'm certainly not a girl or a woman) I dress mostly gender conforming, although ideally I would like to dress and look more androgynous.
But my concern is also that I would just be 'faking it', it's especially odd when considering something like a FLINTA* space (which is specifically a space for everyone except Cis males); What I mean is am I even allowed to go to something like that even though I've never greatly questioned my gender and gone by male for so long?
