This discussion is an odd one, to be sure.
But I'll join in with a remarkable stat....I'm exactly the same size now that I was when I was 11/12 yrs. old! At one time I was about 3" taller. At another time, I weighed 241. All between the ages of 11 & (a week from) 65......5'6" and 165 lbs..
And before Rickochet comes along and says anything, my pecker is probably still the same size also. 😎😉
