The penis is able to get bigger and smaller because it’s made of erectile tissue – inside it’s like a sponge that can fill up with blood.

The different parts of your penis are:

1. The shaft – the long part of the penis
2. The glans – the head of the penis
3. The foreskin, if you aren’t circumcised – skin that covers the glans
4. The urethral opening – where the urine comes out
