I have never been intentionally edged by a partner in real life, although I have been left hard & frustrated many times after some fooling around did not go all the way.
HOWEVER, I was once instructed by a Zity member to edge myself and it was the most amazing experience. It has opened my eyes to this art, and makes me want to try it in person.
The instruction was for a full day of intermittent edging. Each hour I was to get myself hard, and then stroke myself for a given amount of time to maintain my erection. I woke up at 7 am and was to stroke for 7 minutes. Then at 8 am stroke for 8 minutes. At 9 am stroke for 9 minutes. The pattern continued all day long. After each stroking session I had to write down where I was, what kind of lube I used, how it felt, and what I was thinking about. If I missed a session for whatever reason I had to catch up at the next possible opportunity, never missing out on the total minutes. I was not to wear any underwear for the day, and when I left the house to run an errand mid day, my leaking precum left quite a wet splotch soaking through my jeans in the front of my thigh. By midnight I was up to 24 minutes of stroking for my last session.
When I was finally allowed to orgasm it was incredibly intense, both in muscle contractions, and in volume of cum. My strongest orgasm ever.
It was very interesting experiencing different sensations throughout the day. Different types of lube, increasing levels of sensitivity, a more and more swollen glans, lots of dripping precum, and a raw tenderness that hovered between pleasure and pain. The good kind of pain.
It was a fantastic adventure, both physically and mentally. I hope someday to experience edging like that again, but with all the additional benefits and intensity of someone manipulating me in person.
