blak9: I measure along the top with the ruler pressed against my pelvic bone. I use a flexible ruler because my erect penis curves up and to the right. When I took the measurement at the bottom (from my balls to the tip of my head) I came up with 10.5". When measureing girth, I measure along the base of my penis. It measures 6" at the base but narrows to about 5.5" right before the head. The length and girth of my head is small compared to the rest of the shaft. (At about 1.5" long and 5" around.) Tsk... all this neck and a average head. Wouldn't change it though. It makes penetration not as difficult until about half is in.
