Last night was my first edging session since I want to cure my premature ejaculation ( which I think it's no too severe becuse I only have problem controling my fisrt orgasm, becuase after the first one I can get hard right away and last 20 or more if a want. Can you tell me guys why is it happen?)

well my session was for about AN HOUR, I used slow movements arround my glands and when I was about 8 in arousal I stoped and relaxed for a few seconds and kept going again. I noticed that since the first minutes of edgin I felt involuntary spasms which I red causes PE, I would appreciate if you guys give me an exercise to control those spasms.

thanks. Do you guys think I went too far doing edgin?
