How do you develop the ridge on the back of the penis

I really wish someone had an even partially definitive answer to the million dollar question of how to increase CS size. It’s the only thing my unit is missing right now. If I had a nice big CS Chamber, my girth would easily be over 6”.

As westla said, it doesn’t have such a strong tunica. If I’m remembering right, I think the lower half has one tunica layer, and the upper half has two layers(perhaps this is why the upper part is usually less pronounced?).

It’s true that the internal pressures are never going to be terribly high and this is probably a good thing, to keep the urethra safe. Having said that, I would think that the CS Chamber has far more potential for temporary expansion that the two CC Chambers.

Right now I am supplementing with Arginine Ethyl Ester, and that alone has increase my CS size slightly. I will be trying to increase it’s size in the next few weeks. If I’m successful I will report back ;) .
