If you ever look at a woman’s breast (most men usually do, mistaking them for eyes) they appear to be in perfect symmetry. While it may not always to appear this way a woman’s breasts are rarely the same size. To be more precise it is usually the left breast that is the largest one, but the difference is often so small that any size disparity can hardly be noticed with the naked eye. But that’s not where differences in breasts end.
While a woman’s left breast is usually the larger one, the differences also extend to the nipples. It is also very common for the nipples to come in different sizes, shapes and also point in different directions. In rare circumstances some women, and men too for that case, can have a superfluous third nipple.
It may seem slightly odd that breasts, in all their perfection are different in size, but in extremely rare cases some women have an extra breast.
