How do you decide if a penis is small, below average, average, above average, or big? I ask the question because in my own personal situation my penis length (5 inches) is by most standards below average or right at the minimum of what is considered average, however my penis girth (6.25 inches) is well above the average. So where would my penis stand on a generalized scale of small, below average, average, above average, or big?
