It's the body part that men arguably value the most, so you owe it to your penis to always keep it clean, healthy and fit for purpose.

Give it the care it deserves and you may not be the only one to benefit – your partner will probably be grateful too.

Gently wash the penis with warm water each day when you're having a shower or bath. If you have a foreskin, pull it back gently and wash underneath.

If you don't wash underneath the foreskin correctly, a cheesy-looking substance called smegma may begin to gather.

Smegma is a natural lubricant that keeps the penis moist. It's found on the head of the penis and under the foreskin.

If smegma builds up in the foreskin, it can start to smell, stop you easily pulling your foreskin back, and become a breeding ground for bacteria. This can cause redness and swelling of the head of your penis, called balanitis.
