Yes, a circumcised man can still have "dikk cheese" (smegma), though it is less common than in uncircumcised men. Smegma is a buildup of dead skin cells, oils, and moisture that can accumulate around the head of the penis. While it typically forms under the foreskin in uncircumcised men, it can also occur in circumcised men, especially if there are residual skin folds, adhesions, or poor hygiene[2][7]. Even after circumcision, smegma can collect under remaining skin or in areas where the shaft skin adheres to the glans[6]. Regular cleaning helps prevent buildup.
