Welcome to your new breasts. They are going to be with you for quite a while, so let's cover the basics. Although they have no primary function in sexual reproduction, they are sexually sensitive and may inspire sexual desire.
Breasts develop during puberty .
Even though they're not directly responsible for reproduction, they still play a big role in your sexuality. Maybe as much as your sex organs do, because they are more visible and have a lot to do with how you and others see your body. Boobs are cool when you think about it. The main thing about breasts is that they can be as different as any two women are. Almost anything is normal.
