am I nb?

[u/Civil_Beach_2350]

AFAB, I'm 16 and been thinking about gender stuff a lot recently but idk if I'm wrong or not. Prolly not really related but I just found out my old roblox account had a nonbinary flag on the avatar I was like 11 at the time. Dunno if lil me was on to something or nah 💀
I kinda really envy ppl with mustaches and want muscles. Don't think I want to be a boy tho? Don't feel much of a connection to that idea if that makes any sense at all, I think I just want to look more masculine at least?? I also don't mind my chest much but I do wish it was less noticeable/flatter, idk if I'd want a completely flat chest or not tho. I've had thoughts about getting a binder but idk if I should haha esp if I'm wrong
Unsure if I feel entirely connected to the idea of being a girl/woman whatever.
uhhhhh help me out here guys. I can yap a bit more if more context is needed or if my blathering just now made absolutely zero sense
