Puberty is a time of life when your sex organs start working like an adult's. During puberty, girls and boys start to become women and men.
One of the most difficult yet exciting times in life has to be puberty: it's an awkward period between childhood and adulthood when your body rapidly changes. You go through a growth spurt, hair sprouts in new places. Your sex organs start to work for the first time. Hormones are coursing through your veins. Your voice may change. So when you think of puberty, think "awkward stage."
