Foreskin piercing passes through the penile prepuce on the dorsal, ventral or lateral side. Male circumcision is the surgical removal of the foreskin (prepuce) from the human penis. When non-erect, it is quite flaccid and contained within the prepuce (foreskin, or sheath). Occasionally they are found inside the lips, ear canals, prepuce or vulva, and anus. The scrotum, penis, and prepuce are usually coated with a foul-smelling secretion. The prepuce, including the ridged band, is a specific erogenous zone. Non-retractile prepuce in adolescence is normal, common, and usually resolves with increasing maturity. When flaccid, the pseudo-penis is retracted into the abdomen, and only the prepuce is visible. After mating, the male usually licks his penis and prepuce. This covering, called the prepuce, is normally retractable in adulthood. This is called "megameatus with intact prepuce". In rodents, the length of the prepuce is related to urine marking behavior. Later the edges of the cut prepuce will heal. Type I is "partial or total removal of the clitoris and/or the prepuce". It is the site of attachment of the future prepuce.
