Question, Women preferred.?

Okay so my are uneven first of all. It's pretty noticable. Probably a cup size off. One is about probably just getting to a B and the other is maybe an A. Well, on my smaller there is some sort of rash? Or discoloration? It is on the side of my and it is a couple shades darker than what it should be, and sort od spotty. And a little hairier than my other bigger . I have seen a docter about this and they reccomened a special doctor that test for hormones. And I am a younger teenager, 13.
