The thing that I always find amusing is when providers talk about girth with some I've seen stating they have 12" girth, lol.
I assume the following:
Age - If listed as: 20-25 add 5 yr, 25-30 add 10yr, 30-35 add 5-10yr, 35-45 add 10yr
Weight - Add 10-20
Penis Length - Subtract 1.5 inches
Penis girth - Subtract 3 inches
