There are some huge girths on here, but here's my opinion: I think the average girth of a guy is a lot smaller than what we on here think it is. First, there's the data from the Lifestyles Condom Survey on spring break from a few years ago. The mid-point where 50% of cocks are bigger and 50% are smaller is 4.67". Mr. Average - The true story about penis size, from a site that isn't trying to sell you anything. I think that's probably the best survey, but even then, I think there are probably a number of smaller guys who were dissuaded from taking the survey out of fear or embarassment. Then my own personal experience. I'm a bigger guy (7" long) and my girth is bigger than average, but I'm only 5.2" or 5.3" around. And of the maybe 14 girls I've been with, probably 10 of them have commented on my thickness either during or afterwards. And a few of those girls had been with a lot of guys (ie, so it wasn't like they were virgins) and all of them had been with at least 2 guys before me. Anyways, feel free to comment away. I just thought I'd throw that out there. By no means am I nearly as big as some of you dudes, but I think the average girth is a lot smaller than we think it is.
