Our bodies are always changing, especially between childhood and adulthood. This time is called puberty and it is when your sexual and reproductive organs mature.
During puberty you will gradually experience many physical, emotional and social changes. It can seem a bit overwhelming but remember that everyone goes through it. You will probably start to become a lot more aware of your body.
Have a look through the different topics of the 'Our Bodies' section to learn more about puberty, anatomy, periods, sex and gender, masturbation, pregnancy and body image.
If you have a sexual health question that you would like answered, you can use our Ask a Question service.
