So I was alone in a hotel room for a day and being bored I had a look on this 'jackinworld' site that gives masturbation tips and stuff, i read about the 'stop and go' method, this is what it says on the site:
"Get some lube, and begin to masturbate in your favorite position – but right before you ejaculate, STOP! Put your hands down, or put them behind your head, so you don't ejaculate. Let your erection get just a little soft, and then start again, and once again, right before you ejaculate, STOP. If you do this at least four times, not only will it prolong your session greatly, it will make you ejaculate a lot more semen."
I had a go and it worked AMAZINGLY, I lasted almost 2 hours, stopping just before cumming at least 6 times. When I finally couldn't hold back anymore and came it was powerful! the first two squirts went right into my mouth, and the volume of thick cum was ridiculous, had double the amount I'd get from a quick wank. You guys ever tried this while jackin off? Worked well for me! (I hadn't came in 5 days which I think helped too)
