Strange coincidence. A year ago I picked up on the Steve Richfield temperature reset protocol. As part of that I got used to sleeping in really heavy clothing and doing very warm showers in the morning. Really helped most of my issues, except my penis sensitivity and libido went WAY down and it just wasn't what it used to be. I never put the two and two together, until some days ago I read that the testicles work best when at a somewhat lower temperature compared to the rest of the body (???). Since a few days now, I've only kept the heavy clothing from the waist up, and sleep in light loose clothing from the waist down. Things seem to have improved a bit. We'll see...
That's very interesting indeed. I will be extremely curious if you give this ice method a shot. Remember to start slow.
