Jason, at a certain moment in my mid-teens I actually really tried to be feminine and all. I felt great about my small chest, but because everybody was bullying me for being such a tomboy (and then also not having boobs and refusing to shave my legs), calling me "it" and all, asking me whether I am a boy or girl all the time (and they knew! It wasn't a question out of genuine curiosity). The girls would exclude me from their groups, because I was a "boy" and the guys would exclude me from their groups because I was a "girl". I couldn't go to any toilet, cause if a girl saw me in the girl's she'd make a big fuss and shout there's a boy in the girl's toilet (and they always knew), and if I would go to the boys toilet people would say "Hey! What's a girl doing in the boy's?". It was very annoying, I basically couldn't live as ANYTHING, and thus I adapted myself eventually, grow out my hair and wear slightly more feminine clothes (still not pink stuff, but not clothes from the boy's area in stores anymore), and I even started hating my masculine appearance and small boobs, etc. but later when I stopped giving a ->-bleeped-<- about other people's opinions and became more my own person I dropped all of it immediately again, cut my hair, threw out the 'feminine' stuff, lol. And it felt much better right away. Then I started finally opening up for my desire to be masculine, finding out how deep it really went, how strong it was, etc. and I soon felt I didn't just want to be a "tomboy" but a BOY. It still took a lot of time until I dared to express that feeling openly, because I had repressed it for so long.
Also just give it some time. You'll notice soon enough what's right for you 😉 my first step was embracing I was transgender, but still keeping the "Maybe I don't need transition" thought. With that I started accepting I am a guy on the inside, and when I embraced that more and more... well, there's no putting the genie back in the bottle. In time you will know, and if you are still confused you can always go see a gender therapist for more help/advice.
