De-erecting a penis can also be performed physically by smacking the gland hard with the palm of ones hand. A myth shown in movies says that this act is usually done by smoking hot nurses. Though, it is usually done by either a man or a fatty nurse named Ursula.
Another myth says that a physical de-erection is very painful, and that is indeed true.
That fat chick last night totally gave me a de-erection!
"Did you hear that Simon went to the doctor last night?", Said Rick. Jane looked shocked. "How come?", she said. "He just got a de-erection, no big deal"
