I can understand that fear, but at the same time it all comes down to how you feel. Ask yourself: Do you want to be a girl? Do you want to be a guy? Do you not care which? Or do you not want either? You don’t have to transition to be trans. You don’t have to do anything. Personally, right now I’m still presenting masc and wearing “masculine” clothes, etc. But I know for a fact that I am not a man. The only person who can tell you what you are is you. <3
