There is no such thing. The penis is a sponge type organ it is not a muscle.
if you were born with a small one then do what you can with it. dont try all these pills and excersises...lets face it....you have a small wiener so just live with it. remember...its not the size...
No. Exercises do not permanently increase the size of the penis. It is not a muscle and does not get bigger with use.
I am afraid there is no such exercise.
There is no reason to think on penis enlargement unless it is so small as an AAA battery.
