i wouldnt know for sure, as i have only mesured a few guys,[ 1 ] was 1.7/16 across top soft he couldnt get hard enough to get an acurate measure. but the closest i got was around 4 inches to 4 1/4 inches around his cock. the other guy was 2 1/4 across the top and was full hard at a girth an even 5 inches around. another guy was 2 1/8 and had a girth of 6 5/8 inches, the lenth of them was 6.5 6. 51/4 long. now my hubby is the only other guy i have measured recently and he is 2 7/8 across at fullest erection and he is 7 inches around in girth and 7 3/4 inches long. so all these guys are some what close in size but are yet diffrent sizes in girth when compared to width. would be interesting to see where this thread goes i think. have give what info, i know about it but i think i have a new use now for my cloth sewing tape. can use for measuring needles. and thimbles. as well as pin cushions. LOL.
