Over the past 30 or so years, people have been getting taller and generally more healthy. However, according to statistics the average length of the penis is getting smaller. It was always accepted at school that a 6'' ruler should completely cover your dick - AT LEAST. Today, however the average is supposed to be 5 to 5.5''. Now I know there is no way of substantiating any statistics and obviously the smaller guy is hardly going to brag about his 5 incher but there does seem to be a downward trend. Perhaps there's something in the water!
