Improvement with 66day challenge

Been doing this challenge and edging for just over a week now (8 sessions) and I can say that there has been a slight increase in stamina. For example, my first session masturbating, without PONR, was 30 mins with no break at medium pace. My last session was 60 mins without PONR with no breaks, at Medium-fast pace. Avg. over the week was 42 mins with 1 break without PONR. Sorry for all the stats... Bottom line is, I used reverse kegels all the time and tried to counter my involuntary kegels with them (did a reverse kegel everytime I had an involuntary kegel). Doing this for a week + I can now feel that my involuntary kegels are significantly weaker than what they used to be, still there, but not as strong, which is probably why I can last longer masturbating now. I'm gonna move on to using lube now and see how I do. Hope this helps anyone!
