The white emollient under the child's foreskin is called smegma. Smegma is probably the most misunderstood, most unjustifiably maligned substance in nature. Smegma is clean, not dirty, and is beneficial and necessary. It moisturizes the glans and keeps it smooth, soft, and supple. Its antibacterial and antiviral properties keep the penis clean and healthy. All mammals produce smegma. Thomas J. Ritter, MD, underscored its importance when he commented, "The animal kingdom would probably cease to exist without smegma."Yeah, that's a defense of smegma, aka dick cheese. It's clean, ladies! It's necessary!
