Jesus Christ not another one. Not masturbating and letting your balls swell has no scientific proof for anything. It won't help you get more women or cure cancer or make you into the most desirable man in the world. I masturbate not every day like some degenerates but maybe twice a week. I still have regular sex and talk to women just fine. My stutter will fluctuate between fluent and non fluent because of 3 factors. Stress, confidence, and sleep. I believe that's the jist for most mild stutterers too.
