O.K. you know those African chics that put a ring on every year and by 50 there neck is 2 feet tall and would snap if they took them off?
I'm sure the same thing would work for a penis, just wear a stretching devise daily and after 5 -10 years you will have a couple inches for sure.
Also there is the Dick Doctor, there is a about 3-4 inches of penis inside that can surgically be brought out.
