Phimosis

The foreskin is too narrow to be pulled back for exposing the glans. Phimosis has major impacts on body growth. In one situation, the circumference of the glans crown may become much smaller than normal after maturity, as the glans is insufficiently stimulated due to coverage by the foreskin during adolescence. The condition will affect sex sensation and sex life in adults. For those men having much smaller circumference of the foreskin opening, the foreskin can easily get stuck at the crown slit after retraction and thus leading to painful phimosis.

It is shown that cervical cancer is closely related to the foreskin hygiene. Therefore, men need to be considerate for their female partner's health by assuring hygiene of the foreskin.
