Hello, good to meet you
I am a trans man who can hopefully give you some insights.
Firstly, I would like to let you know that everybody’s experience is different, and that no two people are the same. Many individuals question their gender identity throughout their lives, and not everybody who does this ends up identifying as transgender. Questioning your gender identity, and your relationship to your assigned sex at birth, can be an important part of finding out who you are, and discerning what shape you would like your future to take. This is true regardless of which label you end up identifying with.
Secondly, many girls question their gender identity because they feel that narrow gender roles restrict them, and they don’t fit into society’s ideal of what a girl should be. Now, I’m not necessarily saying that you are experiencing this, but I do want you to be aware that this is a struggle many girls experience. Many such females end up being tomboys or masculine women, and explore gender non-conforming presentation as a way of reclaiming their femaleness. Pushing back against gender norms can be people’s motivation for questioning their gender, and this can particularly be true for women in a patriarchal, unequal society.
That being said, perhaps you are transgender! You’re clearly on a journey to find your most comfortable life, and that is valuable, no matter how you end up identifying. The only way to really figure it out is time, patience, and exploration.
Throughout our life, we all experience phases. Phases are not bad. Take your time, and allow yourself a “holding space” for unlabelled feelings. I would suggest calling yourself “questioning” for now, which allows you the freedom of trying new things, and moving between phases as you please.
