Hey, welcome! You sound like a for-real transguy to me, and I think that's very cool. It's awesome that you know who you really are, accept yourself and are accepted by many important people in your life. Because I work in the medical field, and have for many years, I can tell you two things about your breast questions. First, at your age, you are still having breast maturation even though you may not actually see it. What that means is it's risky longterm to bind your breasts. So, if you truly want to look like a guy, you will eventually have to have what transguys call top surgery. The surgeon would call it a reduction mammoplasty. That's a drastic and expensive step. Be SURE before you decide to really do that. Second, you can do "minor binding" with sports bras and certain types of clothes which is much safter and more comfortable than harcore breast binding.
See the wiki section of this website for advice you can trust about this.
We're glad you're here, so relax, get comfortable and settle in. You're accepted here.
