I was wondering just how much a dick can grow when hard. My dick is pretty small when soft but gets to a good size when hard. I've calculated that non bone pressed, it grows almost exactly 100% in length, which is quite abit more than usual, I think. I've read that the average flaccid size is about 3.5" nbp and the average erect size is about 6" bp. If you deduct an inch for the average pubic fat pad, that means that the average dick is 5" nbp. That means that the average dick only grows 1.5". That doesn't seem like much at all, could it really be as little as that? Out of interest, how much do your dicks grow by?
