Smegma is a naturally occurring lubricant that allows the foreskin to pull back. People with a foreskin need to wash underneath it, everyday, to remove the build-up of smegma.
Here is how:
- Gently slip the foreskin back in the shower.
- Use a mild soap and warm water to wash the head of the penis and inside fold of the foreskin.
- Rinse the area well.
- After the shower, dry the head of the penis and replace the foreskin.
