Lets kick off with the TACKLE. The main man, the PENIS gets longer and bigger during puberty. It has two main bits - the HEAD and the SHAFT. The head is the most sensitive to touch. The piece of skin that surrounds it is called the FORESKIN. This can be pulled back exposing the most sensitive part. It is important to take good care of your kit - examine your balls every now and then (about once a month).
