Here is something I must have read somewhere long ago: the coefficient of growth. A simple division to determine the growth of your penis from rest to erection (a percentage%). This idea came to mind as my girlfriend seemed pretty shocked by my apparently 'normal' flaccid penis measuring 4.5", considering when fully erect is reaches a size of 8"...
So here is the calculation:
(Length of Erect penis - Length of Flaccid penis) / Length of Flaccid penis
This will give u a simple percentage to see how much length u gain with an erection... my percentage of growth is 78%, I would like to compare to others...
