Re: Does it matter?
Thre is a slight rumour that race can affect penis size. According to wikipedia - "There are many urban myths purporting correlations between various races and penis size. However, to date, there has been no conclusive evidence that race and penis size are at all correlated. All studies to this effect have been rejected by the scientific community due to inaccuracy, respondent bias, or unverifiable claims."
Rest asured, masturbating does NOT make you go blind!
