Preputial sac

Urination
Everything in the preputial sac is covered with [[Mucosa| mucosal membrane]] (similar to the inside of your mouth), which likes to be wet, so no damage or threat to health is caused by having urine inside the foreskin. The sphincter action of the preputial orifice functions like a one way valve, blocking the entry of contaminants while allowing the passage of urine.<ref name="fleiss1998" /> The urine will help to flush contaminants and pathogens out of the foreskin.
The [[foreskin]] overhang or [[acroposthion]] may be used as a hose nozzle to control and direct the stream. It may help to stretch one's foreskin out from one's body. One man said, "When I need to pee, I open my fly, pull my foreskin out and give it a tug to get any wrinkles out, then I hold my foreskin with the thumb and forefinger of both hands and use the overhang of my foreskin to direct my stream. When I finish, I milk it a bit to get any residual pee out of my [[urethra]]."
One may pull back or not pull back when urinating. Either way is okay.
