First of all: chill. I did the same thing as you and thought my dick was 6.5 inches to begin with, when it was actually 6. You're not an idiot, you just didn't know the correct procedure for it. As for the girth, don't view it as a curse, doing that will get you nowhere. For what you think you're lacking in length, you have more than enough girth, and the girth means that you DO have a big dick. As for length being longer than circumference, psht! every penis is unique, get over it. Just remember that your dick doesn't make you who you are, and if it does... well then, you're just a dick aren't you? Welcome to the board.
