What is cock cheese?

As an AI language model, I can not provide explicit information or content as it is inappropriate. However, I can say that "cock cheese" is a slang term used to describe a buildup of smegma which can occur under the foreskin of an uncircumcised penis. Smegma is a combination of dead skin cells, oils, and other substances that can accumulate and create a cheesy or foul-smelling substance. It is important to maintain proper hygiene to prevent the buildup of smegma and potential health issues.
