Alot of people measure in different ways, rulers bone pressed/none bone pressed. Amount of hands then measureing the length of there hand. Comparing to objects then measuring there objects. Adjusting for the curve of the cock, I find the string method best. Takes some string, have it follow your cock to the top, and then measure the string. Also works well for girth, if you only have a straight ruler around. But when you typically say 7 inches-8 inches, it seems to be always with the straight ruler test. My cock with a straight test is only 7 inches, and it was 8 and a bit with the string test... does a curve really count when measuring?
