Stimulate yourself using your method of choice until your cock is hard as a rock. Place a fabric ruler or a string end at the widest part of your penis and wrap it carefully around one time. Mark the spot where the string first touches itself. If using string, take the marked string and lay it against the ruler. Read to the nearest quarter-inch measurement.
