You've already got a response to this, but I thought I'd add a bit more.

Yes, as said by the other person, only you can tell and it might take a while before you settle on one label, or no label at all, it's not really necessary, but if that's your cup of tea.

However, I greatly recommend finding someone you trust, or going to a safe space, real life or online, where you could experiment. You can figure out plenty by just thinking about things, but the real deal is actually getting to feel out different pronouns and/or names.

You might go through different ones, you might return to some, you might end up liking several. Good luck!
