Imagine you are questioning and don't know anyone who isn't cis whom you could look to . You do, however, have a close, longtime friend and you are confident that he will accept you no matter what (in my case, calls me his little brother). You're thinking about telling him that you're seriously questioning your gender identity, haven't told anyone else, and are hoping for some support/guidance/etc...
What would you say to start it off? What might you ask him?
