I call it the AA15 technique. The best way to express the hidden penis is erect stretching, but no one has used the isometric principle with it, and let me tell you it makes all the different.
I get erect then clamp off at the base and under the glans, and then pull and release in small pull ups and let go, i can really feel the stretch in the hidden penis and it is a dull ache. I use a bouncing rhytHydromax, like boucning a ball or how a women would bounce her boobs up and down, so its not a simple pull up and release, its up down in a particular rhytHydromax.
I take no responsibility for injury, this is for information only.
