Gender and gender expression are vast and complex things, may I suggest reading some trans women experinces (in no way do you have to have the exact same to be valid) and dabble in the ideas of gender and expression.
Liking makeup doesn't mean your a trans women, but it can be a sign you want to be precieved as more of woman in the world, which is a sign of being a trans woman (from what I have heard from trans women/trans folk) , you talked about having breast which could be another sign of being a trans woman wanting the anatomical form of a "female" body, I am not trans so try reading up on trans voices <3
But like you said it may be a tricky situation <3 don't feel rushed being trans is one of the more difficult identities <3 people aren't the kindest to transgender people (which is disgusting and so sad, use someones pronouns and respect trans identities <3)
Don't feel pressure to have everything figured out or to be "a pretty woman", I know thats hard for a lot of trans folk grasping how they physically look isn't how they authentically are <3 but trans bodies are beautiful <3 never be ashamed.
If you ever decide to change your pronouns (after you have gained comfortablity) let us know which ones you would like us on adisc to call you, I have heard from trans folk pronoun use helps a lot with feeling mattered <3
Awh well for what its worth <3 you seem like a swell guy <3 and you're valid
