I know people are in disbelief about this. My stutter did actually lessen during my NoFap streak. Though, I think it was because I gained more confidence after starting. May be solely because I stopped masturbating or may not be. To each their own. I do recommend people to try it though since it might help. After I relapsed my stutter returned to its normal state, but slightly more fluent. Weird thing the human brain is. One thing for sure is that NoFap CAN boost your confidence. Again, take my words with a grain of salt. NoFap isn't a one-hit wonder cure. Just that it may help you.
