So the idea came to me to experiment with two modalities:
The first is a wild idea yet I wanted to try it. What is the idea? To pump with organic brewed coffee. I was looking at the various benefits of organic coffee and I decided to add organic coffee grounds to the hot water in the tube and use that on my third set and the last set.
I am calling the modality "caffeinated pumping."
The other modality I experimented with is contrast water pumping. I place my penis in cold water and pumped at 7 HG for 1 minute then I went to hot water at 7 HG for 1 minute.
The feeling was interesting and the benefits of contrast showers could possibly apply to PE.
I have another experiment that I wanted to attempt that will involve gases and I'll explore that and post about that.
