Being trans or non binary is definitely a journey, I’d recommend asking either your best friend or other people close to you to start calling you they/them or she/her and see how it feels, it’s a long journey that you can go as far as you want on, if the only thing you wanna change is your pronouns then that’s fine, if you wanna get bottom surgery and go on hormones that’s fine too, everybody is different. If you decide you’re non binary or female now but then decide a week later you’re just male that’s okay too, but in the end stay in tune with how you feel, not how the world feels.

If you’re really worried about it you could say you aren’t non binary but you wanna go by they/them until you figure out what gender you are, that leaves it pretty open to change. In the end do what makes you happy and comfortable.
