I got my layout at
Scientists have determined that the average time
of intercourse lasts 4 minutes. The average
number of strokes is 9 per minute, making the
average intercourse 36 strokes.
Since the average length 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, are you getting your half mile every year?
