that thin paper cover is actually several thousand times thicker than your typical herpesvirus, papilloma virus, immunodeficency virus, or hepatitis virus. It is also several hundred times thicker than bacteria that cause gonorrhea, chlamydia, or syphilis. the paper will also prevent bugs like crabs or other mites from running into your crotch.
gotta use the protection people. your immune system can't do anything against these viruses or bugs, and you'd be damn lucky if it nailed these bacteria.
I always say, there ain't no difference in sitting on it or licking it.
