So... I don't know what I am. Some days I feel like a girl and want to wear pretty dresses and skirts and do my makeup and stuff, but sometimes I also feel like a boy and want to wear boys clothes and bind my chest and that sort of thing. I have also had a couple of days where I just haven't felt like a boy or a girl and haven't known how I want to present myself (I still don't know how to present myself on those days), but sometimes when I feel like that I bind my chest but wear girly clothes, or leave my chest unbound and wear boys clothes. I am honestly really confused, especially because I don't know whether I prefer 'she/her' pronouns or 'they/them/their' pronouns. Idk, it probably makes no sense
Gender expression doesn't define your gender identity. It doesn't matter how you dress on those days. If you feel like a girl some days, a boy some days, and neither some days, you could definitely be genderfluid.
