GREAT ARTICLE BELOW: "Each and everyone of you is a product of natural selection. Guys, that means that your daddies, and their daddies, and their daddies... were PICKED (ie selected) by the women of their time. If they didn't like what they saw or felt in dick size, presumably they would have left and found someone else. Another way of putting it is, you are the product of past desirables, which would include your dick. So if the "average" range of dick sizes is between say 5 and 7 inches, then that indicates that females have been selecting that size on average for thousands of years. If the ONLY thing that mattered was a big dick, then all males would currently be very large (10 inches or more?) since past females would have selected only the biggest size. Strangely, but as a matter of fact, you have (past) females to thank for whatever size you are now. I know that most of this will be waisted on most of you. Statistically for every "large" male there is a similarly sized female. Big penis genes can also produce big vaginal canals."
