Found a new way to play and cum earlier in the week.

Using two fingers on my sock cock i jerked off until I began getting hard.
Stopped and waited until it got soft.
repeat.
eventually when I began getting hard noticed I was right on the edge and then stop.
repeat numerous times.
Eventually i got closer to the edge quicker with cock still completely soft.
repeat numerous times
eventually able to cum in seconds on a completely soft cock.

So hot! cum dribbled out rather than spurted and ran down my cock, but orgasm super strong.

can't wait to try again.

anyone done anything like this before?

Yes, I had a very experienced girlfriend back in the 80's and she used to do this technique on me. It was mind-blowing. Luckily, she was a good read of body language (she knew my build up and climax body behaviors) so she was able to stop me every time before orgasm. She would even lick up the clear pre-cum as we went along. It takes time and patience to wait for the erections to subside, but once you get it - partially flaccid orgasms are incredible!!! (I think she enjoyed my torture, albeit very exquisite torture)

that is the only way i can get my cockhead into my own ass. keep edging then back off. after awhile I can push my cock down between my balls and push the head in. I have cum this way a few times but it is such an awkward position I can't feel the cum going in.
