A clear and age-appropriate explanation about masturbation and body changes for 12-year-olds.
It's normal to become curious about your body as you grow up. Masturbation means touching your own private parts to feel good, and many people do it as a way to learn about their body. When you touch yourself, especially around the penis, you might notice a white, sticky liquid. This is called semen, and it's made by the body starting to go through puberty.
During puberty, your body changes and starts to prepare you for adulthood. Semen contains sperm, which can fertilize an egg when someone grows up and decides to have children. For now, it's perfectly normal to explore your body safely and privately. Remember to wash your hands before and after, do it in a private place where you feel comfortable, and never feel ashamed about natural body changes.
If you have more questions or feel unsure, it's a good idea to talk with a trusted adult or a doctor who can give you more information and support.
