It’s not too hard to imagine what perineum sunning looks like. It involves exposing your backside to the sun for a short period of time.
Some people lie on their back with their legs spread wide in the air. Others face away from the sun and lean over so the rays have direct access to their perineum. Of course, the idea is to do it naked, meaning perineum sunning is best done in a private space.
People who regularly sun their perineum say you should only do it for between 30 seconds and 5 minutes. If you're sunning your perineum, remember, UV exposure can cause DNA damage that causes skin cancer formation.
