Thanks for the kind words guys, they help
The weird thing about my rewiring is that when I had those incredibly high levels of pleasure it was a week before, I then came back to normal in a matter of hours and was fine the following days. It's when I stopped completely any stimulation a week later (due to testicles pain) that my feelings slowly went crazy. Probably the lack of stimulation is what triggered this longer lasting hypersensitivity state. Isn't gentle and subtle contractions advised anyway to awaken things more? Without wanting it's exactly what I did :'-)
But yes, I'm getting better day after day and I'm confident I'll be out of this soon, I feel way better than a month ago, which was I think the "peak" of my crisis, and I see this is fairly common. Damn scary and uncomfortable, but common. Will keep you updated
