I just wonder what causes a dick to get that thick? I'm also in awe of a guy that has 9 and 10+ inches in length. What causes them to grow that long? I've had 2 friends that had such length and girth. One of them told me his length, 9 inches. I don't know if he knew the girth. The other guy told me his girth but would not say what his length was. His girth was either 7 1/4 or 7 1/2 inches. I forgot which of the two. But he kept his length a secret. I saw him one time with a simi erection and it was quite long. I mentioned I had seen his dick that evening as he was walking out of the shower. He said it gets bigger than what I saw. The first guy his was so thick he couldn't wrap his hand all the way around it. He had a big gap between his thumb and middle finger as he held it with an erection. Both of these guys were straight, and also circumcised. I just wonder why their cocks grew so big? And then there's me. : (
