I might be trans? Watch
You sound like a teenager who still hasn't worked out quite who they are and what they like. You do not sound like someone who is trans.
It might be worth looking into gender fluidity, if you haven't already, given you mentioned sometimes feeling like a boy and sometimes like a girl.
Try not to rush through any of this or put pressure on yourself to reach an answer because you run the risk of finding one that you may later disagree with. There is nothing wrong with taking the time to be sure, however long that may take. You will learn more about yourself as time goes on, and your situation will become clearer.
