To answer the OP's question, yes I have tried and I have gotten results. After seeing a few providers and losing my v-card, something was wrong because I had trouble staying erect and sex didn't really feel good. I couldn't even enjoy oral sex. So I abstained and did the sort of dipping your toes regiment, it takes 1 month. You masturbate 2 times in week 1, 2 in week 2, and in 3 and 4 only once I believe. Something like that, scaling it back. Or you can do the hard reboot with 90 days of none.
After doing the month regiment or so, I saw Berlin Black (now retired), and I tried the whole sex thing again. The cbj wasn't doing it, cowgirl and mish weren't getting me, but doggy absolutely wrecked me and I finished my first time with FS. So I figured the regiment worked a bit. I also saw another provider beforehand but we never got to FS. After I had some job troubles, I quit pooning because no money. But I got a new job, and made it to 43 days of no jerking. Its easily one of the hardest challenges. It comes in giant waves, so for a few days you're chill, then ne day you're just a big ball of bunched up hormones and a stiff breeze or a milf on the street will leave you struggling. I was aiming for the full 90 and quit at 43, saw an older fob asian sp and was able to nut with oral in a few seconds. Not fapping sort of resets your brain, as a lot of younger guys are accustomed to porn. You need a hard grip or lots of visual aid to finish. After that stint of nofap I was able to enjoy oral sex a lot more.
