Confused about being trans

So i’m an 18 afab and for the last year i’ve felt like i’m trans. I remember thinking stuff like that when i was around 7&8 like just wanting to be a boy but everyone myself included just figured it’s because i’m a mask lesbian. I’m super masc nothing feminine at all really and i hate my chest i use trans tape to get over that. I wanna know what it would be like if i had facial hair and i’m just pretty dysphoric. I’m not sure if i am trans like my gf thinks i am and many people around me ask me if i am and i haven’t come out as anything like that. My friends all naturally adress me with they/them pronouns. I’m thinking i might be trans but i’m not ready to accept it i feel like i’d never be able to tell my family. I’m also insecure because i’m only 5’2 and feel like i need to be taller. If i was born a boy i’d be happy but i’m not happy with wanting to transition into one. Somtimes i just want to be content with being a masc lesbian. just looking for some advice.
