Let yourself explore in a way that feels safe to you! Try clothes, try names, try pronouns, try presenting yourself differently in person or online, look at yourself in ways you haven't before. Do new things, and try your best not to hold yourself back out of discomfort. In the first months after discovering my identity I tried on so many clothes. I shaved my legs, my underarms. I havent done so in years nowadays but at the time it was some of my first experiences with my own femininity.
Spend time with people you feel comfortable tlaking about this with. Be that in person, online, on voice chat, in games, whatever it may be. Ask them who they think you are, ask them who you are to them. Say it's a mental health exercise or something. But even if that's not possible, think of how other people perceive you. Consider how you feel about how other people perceive you. Write all the things people say you are or perceive you to be in one column, and then in the next column write how those perceptions make you feel. Maybe even write down some of the ways you want people to perceive you. Those feelings can tell you something about who you are, about who you want to be.
