This belongs in boys puberty
Don't worry about stages. It won't make a difference and they're not entirely accurate anyway. Whether you're early, on track, or late it won't matter. Don't worry about it so much and just let it happen. So don't be over concerned about it. They don't tell you much.
You seem to be developing just fine for your age so I say you have nothing to worry about other than just to wait for puberty to complete (which is around your 20s).
