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.

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

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.
