hey, so.. i've been there ! i've been identifying myself as trans ftm for like about 5-6 years but after a while i started feeling uncomfortable with that label. it took me about a year to finally have the courage to tell everyone. i basically did it by telling everyone i'm changing my pronouns (in my case from he/him to she/they). surprisingly, no one gaf lol. i was def overthinking this. it won't be as embarassing as u think i promise
it is your gender identity and u don't owe anyone any explanation if people start having questions. everyones journey is different and if u come out as a girl and people don't respect that, then maybe it's time to let the trash take itself out. u have the whole life to figure out who you are - whether u wanna put a label on it or not. that is ur personal right. and i get that it can feel like ur lowkey betraying urself or some shit (at least it did in my case lmfaoo) but dude people change and so do their identities and its completely fine. u are still u after all.
maybe ur genderfluid? cuz u seem to enjoy both experiences of being a girl and a boy (i feel it btw haha). in my case i still don't feel 100% like a girl but i just decided to present myself however i want and not put a label on it. tbh seems like the easiest solution phaha but yea like i said u still have soo much time to figure things out !!!
i wish u good luck on ur journey <3
