Edging yourself has its own specific gravity, its own forceful allure. If you're walking around with your dick hard and throbbing, precum coating it, it'll help you think of sex more and become a self-perpetuating cycle where the allure to perform the action exceeds the importance of some other thoughts. When you have time, you'll edge. When a lover touches you and finds not an ordinary cock, but one that has been edged so close, and you find yourself unable to quite tip over the edge so a welcome lover's touch is all the better, because your lover will make you come with no regard for your edging regimen, unless you ask, and the temptation to ask might be very real.
This file works just as well alone, you'll simply have to set up a mechanism by which you permit yourself to come, or grind on something, or vibrate over the edge. But once you know how good it feels to come after three days of edging every chance you get, fantasizing actively, indulging in fantasy, might you not want to wait until four days, or more, to see if the release gets better?
Learning how it feels to touch yourself in ways which feel good, but won't get you off, is another treat in this conditioning. Some angles of vibration or stimulation will never get you off but will get you close enough to qualify as edging.
