Your balls are precious pieces of equipment and when you go through puberty they change. The most important thing to remember is to:
Protect your balls at all times!
Wear a protective cup when playing contact sports or ball sports such as cricket and baseball. There is no worse feeling in the world then getting hit squarely in the nuts. While extremely funny to watch when it happens to one of your mates, it’s an experience you never forget when it happens to you.
