As you know we the body starts to kegel automatically when you're about to ejaculate.
I've tried to kegel harder when I'm close to ejaculating but that didn't help.
Edging (start/stop) does help but it isn't always appreciated by the woman to stop (specially when she's close to orgasm).
I tried to kegel longer, about 1-2min kegels during my edging to be able to hold on longer and I noticed that every time I let go of the kegel I removed some pressure.
This seems logic since the body automatically creates the pressure (and kegels) when you are about to ejaculate.
So I tried a new technique. I tried to kegel as long as I could during my edging (it's most important that you kegel before your PONR). Let's say that my PONR is about 1-2 minutes away, then I start to kegel. By kegeling I build up the pressure the body wants to build up and you'll feel that the PONR is coming closer because of the long kegel. Before reaching the critical PONR, you stop to kegel.
By building up false pressure by the long kegel you trigger the body to ejaculate. The important step is to let go of the kegel and release all the pressue you've built up.
You'll notice that it feels normal again and that you can edge more.
When I did this earlier today, I felt that I could last forever.
This, unlike the stop/start method removes the pressure. The start/stop method is great but when youv've egded long enough you'll have to stop every 20-30 seconds because of the pressure.
I don't have prematre eja. so I don't know how it works for guy with that. problem.
But give it a serious try guys.
If my description wasn't clear enough, let me know.
