You know what the problem is guys, the �naked people movies� big dick size myth. I just saw the thread about Lex Steel claiming he is 11 inches :D:D when girls think it is 11 and they believe it, 8 will be average as Lex Steel dick is not 11, it's 8/9 maybe, so they will think of 8 as average but in reality it's 6 and 6 is somewhere near the average, so that's the size what they are really thinking about. Plus, chick these days want other girls be jealous of their boyfriends/lovers having a big cock. So if you says 8 is average, she most likely want to be cool chick in the group.
Hands size, feet size, nose size, not much to do with the size of your penis as everyone has mentioned it already, especially if you do Penis Enlargement regularly.
