In uncircumcised males, it is most common to grip the skin of the penis and move it up and down, resulting in repeated sliding of the foreskin back and forth over the head of the penis until orgasm is reached.
Uncircumcised boys need to be instructed that the foreskin should be pulled down daily to expose the tip of the penis, which should then be washed with mild soap and water.
In older boys or adults, an incision is made around the base of the foreskin, the foreskin is pulled back, and then it is cut away from the tip of the penis.
In some babies, hemophilia is suspected immediately when a routine circumcision (removal of the foreskin of the penis) results in unusually heavy bleeding.
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.
