No, the papules do not form due to lack of hygiene, while their presence requires particularly careful washing of the penis. Residual urine and mastic – whitish discharge with an unpleasant odor accumulate in the sham groove and under the foreskin. In addition to unpleasant aesthetic sensations, this can also cause inflammation and even narrowing of the foreskin, particularly painful during erection. Therefore, frequent washing of the genitals (water with soap is sufficient) will keep the skin and mucous membrane in good condition.
