ANDY'S ANSWER: Nipples, like breasts can come in all different sizes and shapes and colours. There is no textbook "right" way for them to look. They can even be different from one another. A nipple's primary function is for a baby to be able to nurse from, and it doesn't sound like there's anything wrong that would prevent that. Unless there is something that is hurting you, don't worry about it for now. While you are developing, all sorts of things can be going on. It's probably just better to wait and see how the finished product turns out.
