I have masterbated and have had intense orgasms without ejaculation. It would feel like my prostate was buzzing. I haven't experienced it in a while but it was awesome.
First anatomy. I edge long term (masturbation without ejaculation for an hour at a time) with ejaculation in two three days. That is not set in stone because I have had an orgasm two days in a row. When a man is close to ejaculating, the testicles retract and in some cases cannot be seen just before ejaculation. So the cock and ball slings for me come in play to help delay that point of no return. I have from a company called Oxballs a 8-ball cock ring ball stretcher and several Grip Padded Silicone Cock ring both black. Both work, and they have to be well positioned for comfort. The 8 ball I love because it really does the job. But again caution regarding putting them on well. The Oxball site caters to gay men but, some products the sell does help those like me who like to edge and delay ejaculation.
Not at all frustrating! Been edging since my mid twenties. It is a way to really enjoy long term sex.
Edging is great....would you rather have a lot of "7 out of 10" orgasms and one ten, or just one quick nine or ten ?
I wrote a a thread on edging. I was taught in my mid twenties, it took a year(!) to learn control, but since been edging ever since. I also learned how to use cock and ball stretchers to help delay ejaculation because the testicles retract just before ejaculation. I can edge for an hour easily, and a second hour if I want that same day and enjoy fully the sensation. Regular masturbation is what, 8 minutes with an orgasm that last 3-5 seconds then off the cliff! Plus edging builds semen volume so when I do ejaculate it is quite powerful.
