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,
I'm sure there is someone out there that will help ya !!
