I started edging when I was a teenager. Now 51 and still at it. I'm pretty skilled now and have edged many men over the years. I've received some very surprisingly high praise from nearly all of them, including other seasoned edgers. It takes a good technique and the ability to read the body indicators. I like to build a man up at a nice speed and then work him in a way that holds the pleasure sensation, fluctuating at the highest levels possible, continuously, without quite achieving a session-ending climax, until I choose to. If you know how, you can keep yourself or any man quite close to the edge for many hours, or for as long as he can physically last. The longest single edging session I've done, without breaks, was about 9 or 10 intense hours. Finally had to take a break for food, etc. :^)
