Less than 1 percent of men are 8 inches or larger. I myself am just over 7 inches. I wasn't at my full potential but I was pretty happy with the result. Anyway now adays it's hard....uhm I mean not as easy to get it at full mast just like that without better inspiration than an empty room and a ruler.
Let me share some life experience. I can't say I've been with a lot of girls, I really haven't but I can still say I've ranged from a virgin to a very, very experienced girl and learned that 7 inches can be a bad thing. In the moment they'll tell you to go in deep and they'll even really enjoy it but when it's all said and done and they got serious stomach cramps all of a sudden you become the Devil in their eyes. Knowing this I'd trade an inch in length for a half inch around. That's not to say I'm lacking in girth, I'm not but it really is the thickness that counts and that 7th inch pretty much goes wasted.
