Male Body

There's no such thing as a 'typical man' – everyone's body looks a bit different. But in this section we look at the things men have in common, like the changes that occur during puberty and the personal care that a healthy body needs.


Overview: the male body

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.

Penis shapes and sizes

Penises come in all shapes and sizes. And they all look different: straight, curved, long, thick, thin, circumcised, uncircumcised. One is no better than the other.


If you get really aroused, you have an orgasm or ‘come’. When you have an orgasm, you ejaculate – semen comes out of your penis.

Keeping Clean

When you kiss or have sex, it's nice if you’re clean and smell fresh. Brush your teeth, shower regularly, and wear clean clothes.


Men are born with a foreskin – a skin that covers and protects the penis head.

Puberty in boys: what to expect

Most boys notice that their bodies start to change anywhere between the ages of 9 and 15. Some boys start and end puberty earlier than others.
