Cockring pumping
After experimenting with using a small 1/2 ring of inner tube as a cock ring during pumping…I decided to try and find something better.
I have a gravel cleaner tube for my cylinder, and after many different options for the opening, to make it more comfortable, I found that white Plastidip is hands down the very best.
I had used several layers to build up the lip, and found that as it built up,it was having a cock ring like effect.
I finally decided to add enough layers for a real strong cock ring effect. Well, since I did that, even my usual 3 in hg, which is usually perfect for me, no skin damage, is now producing red spots. I even went to condom pumping to protect the skin, and still get red dots on my unit.
The sensation is very intense, like a super hard erection, so I know that I have it just about perfect for where I’m at now, and its causing a significantly higher net expansive pressure (internal expansive pressure-outside compressive pressure).
Don’t ask what kind of results I’m getting, because its too soon. Also, its not how much force/time you use, its finding the right force/time vs recover that will determine gains.
I will say though, for those that are looking for a way to increase net expansive forces during pumping, this is really effective.
