Some teens struggle with their self-esteem when they begin puberty .
That's because the body undergoes many changes when puberty starts. And many people worry about what's normal during puberty. But puberty doesn't proceed at the same pace for everyone. Puberty usually begins with a growth spurt. Usually, this happens to girls first but guys tend to catch up with their own spurts around the ages of 13 or 14.
