Scientists have determined that the average time of intercourse
lasts 4 min. �The average number of strokes is 9 per minute, making
the average intercourse 36 strokes. Since the average lenth of a
penis is 6 inches the average girl receives 216 inches or 18 feet
per intercourse. �The average girl does it about three times a week,
52 weeks annually. �156 x 18 feet makes 2808 feet or just over a half
of a mile.

So girls, if you are not getting your half mile every year,...
you better get busy!
