Signs of improvement?

I personally think the reboot either can or should help with both ED and DE based on simple logic. With DE, you are holding off on orgasm and building up for a quicker potential release. When you get the erection on the phone after 8 days of no porn, no orgasm that is a good sign since you are becoming aroused more easily (and thus should be able to get off with her more easily). As far as ED, it should help also. Waiting should make it ultimately easier to achieve erection since your body will again be craving orgasm. A positive result is guaranteed in neither case. As a side note having less anxiety may help even more than nofap with both problems. Keep that in mind.

One of the most powerful tricks I ever learned about sexual relations with women is to not care whether or not I got an erection or was able to have an orgasm. Instead I just enjoy a woman's sexuality. I know there are always steps I can take if I ever have performance problem, but it is best to cross that bridge when you come to it. Worrying over it may cause it which you don't want in this case. Focus on her and not on you and she will notice and you will likely both be happy.
