Behind the tip of the penis sits a fold, where smegma collects. What does this consist of?

Explanation

The tip of the penis is super sensitive. Around it sits the foreskin which can be pulled back in grown men. Behind the tip is a little fold where smegma is produced and can collect. Smegma is a combination of exfoliated (shed) epithelial cells and sebum. It can be washed away with water. If you don't keep your foreskin clean it can become irritated. In the worse case, it can lead to an infection. Some boys do not have any foreskin because it has been removed due to religion or simple tradition
