[confused]

There is hardly a woman in the world with exactly symetrical breasts, its one of the things they always complain about

On that basis it is entirely possible that yours won't be even, either, but that's life and there is no way of predicting the outcome. FWIW, mine are a little uneven, have been right from the start. My right side is slightly larger than the left. The size and tenderness/sensitivity of the the bud is also different, although that does swap about with time and I just think that means that sometimes one side grows faster than the other.

As for final shape, I'm not aware that there is anything that you can do before you start that will have any influence. As you say massage is said to help, but I'm not sure that anyone can really be certain and on a similar basis, one sided noogling might help. Again, many of the female members of the forum are here exactly because of unevenness of one kind or another.

Thanks for the information.

Bottom line are the 2 questions,(A) " Do I wants boobs even if they are imperfect?" and, (B) " Do I want boobs but ONLY if they ARE perfect?"

If the answer is "A", then go for it. If the answer is "B" then drop the whole thing and walk away right now.

I don't think there exists "perfect" anything. You make it sound as though
there are only "perfect" boobs and "imperfect" boobs, when in fact there
exists a whole scale of "imperfectness". Different people perceive the scale
differently. Someone might even like having a boob on the right side and
nothing on the left side (to illustrate the extreme). So I'd put your question
more like "How much imperfection are you willing to accept?".
