Recently i have added side upward fulcrum stretches to my routine. Its a great stretch, basically is a V stretch with the side of the penis relying on the fulcrum.
I believe that is far better than the original V stretch, because you can target the tunica in a more effective way and you can feel it while doing it, its more intense.
I cant find any positive feedback for this stretch on the forum(except for Marinera’s thread) so i will track my progress with it. I am sure that is one of the best length exercises.
