A recent study revealed that the average length of an American Man’s erect penis is 5.6 inches. Oh, penis size. Men and women alike can’t get enough of figuring out whether or not guys measure up. But why whip out the rulers and care so much about length? Isn’t girth where it’s at anyway? To get to the bottom of the size debate, I spoke with Claire Cavanah, a co-founder of the Babeland chain of erotic shops. Who better to assess the value of a rod than a curator of sex toys?
