The sheath can be shaped to cover and adhere to the penis; it can be attached directly to the glans; or it can be fastened to the end of the foreskin.
The foreskin of the penis safeguards the sensitivity of the glans and shields it from irritation by urine, feces, and foreign materials.
A penis sheath is a supplement to the male body enclosing the glans and penis, leaving the scrotum uncovered.
Glans penis-The cone-shaped tip of the penis.
The orifice of the urethra is about an inch below the glans clitoridis and is slightly puckered.
The skin of the penis forms a fold which covers the glans and is known as the prepuce or foreskin; when this is drawn back a median fold, the frenuluni praeputii, is seen running to just below the meatus.
After forming the prepuce the skin is reflected over the .glans and here looks like mucbus membrane.
