I'd like to get to a C, but who knows if that will happen naturally or not. It seems to have the biggest selection of bras is my main reasoning. Right now I have B-cups and I'm not unhappy with that as it's big enough to pass as female without a shirt on. If I don't get any bigger, breast surgery is still something I'm still toying with as I have heard a large percentage of women lose any sensitivity in their breasts if they do so and I may just stick with what I can get naturally for that very reason.
In regards to it not shrinking at all, I'm ok with that, because it means more material for SRS.
