The most vulnerable part of the penis
It has been mentioned before by others about a stinging sensation that develops just under the glans on the top side from stretching or jelqing. I have had this sensation too, and am not sure what it might be. Not sure if it is stress on the dorsal nerve. I use a Penimaster pro vacuum attachment to stretch with and so there is no direct pressure put on the dorsal nerve, a common problem with noose stretching. The glans just under the ridge, where this stinging sensation focuses marks a point of transition for the structures of the shaft. This is where the tunica albuginea terminates, and I’m not sure if ligaments secure the tunica albuginea to the underside of the glans to stop the top side becoming detached from the shaft. I see this place as the Achilles heel of penis extending. I’m currently jelqing with an overhand grip, stopping short of the glans, but I feel stretching (max 6kg as present) is crucial to gaining length. Feedback on the likely nature of this problem is much appreciated.
