Our parents, the media, or other kids all influence the way we think about our bodies. But we can decide to respect and accept ourselves and the bodies we have, even if others don t. We can look at our bodies for what they are - ours. During puberty, things happen inside the body, too. Most girls start having periods.
Most boys start having wet dreams.
And girls and boys begin having a lot more thoughts and feelings about sex. Important changes are happening inside the body. The reproductive system is maturing. Boys begin producing sperm - the male reproductive cells. Girls ovaries begin to ripen eggs - the female reproductive cells.
