I read something in what you write that highlights the "toy" / "fetish" side of things.
You mentioned "the size whre I must use a bra". Reality is... there is no such size until DD. Bra come in AAA sizes if you want to wear one, and boobs don't get heavy and uncomfortable until DD or larger. It's really up to you how fem you want to present. Tha's a conversation worth having with your inner self.
