2.
An effect on the head of the penis from excessive and/or overly vigorous masturbation, in which a blood vessel bursts and blood leaks within the head of the penis causing discomfort for days. Very much like a CVA (cerebral vascular accident) or stroke, however more accurately described as a PVA (penile vascular accident)
I was vigorously masturbating last night and then pow it hits me... there was blood all over the tip of my cock except it was under the skin ... cock stroke.
