Edging Not Ruined Orgasm

I had a wonderful time last week. Took the day off, wife at work. Showered, shaved my balls. I got all my porn sites up on my laptop as I layed on my bed all naked and clean and horny. I spent about an hr surfing and stroking my cock to everything that I could find. Leaking good by now, I started to just barely fiddle with my throbbing engrorged purple head. Teasing it slowly. Precum is flowing good now and I am quivering all over. I continued this for about another half hr, just barely rubbing my head and stopping at times.By now I can feel my prostate stinging for me to let it release. My dick was as hard as I can remember, push down, spring action back. I finally needed to finish my wonderfull alone time. I rubbed my head for another 20 min. slowly. Right when I was about to cum, I stopped. Well it was to late. My cock was pulsing on its own with no help. like a ruined orgasm. But, after about 5 seconds I started stroking it hard and I started yelling it was so good for the next 10 seconds. It was like I had a prolonged orgasm because I stopped for a few seconds. Wow!!!!!!!
