Speech Therapist and person who stutters chiming in here. It is interesting that you correlate masturbation with stuttering. Even more-so with confidence boosting. In general, masturbation is a healthy human activity. Many published articles indicate this. It seems that by resisting the urge to self pleasure builds up self-esteem about successfully overcoming an urge or something we can not control. Without intensive speech therapy it is difficult to control our stuttering. I can see how this overall mentality could lead to a placebo effect concerning a person who stutters. Some fun questions to think about regarding this topic: * Does this same effect work with the female population? * It is the same with people who have frequent consensual sex with a partner? Why? or Why not? * Does a build-up of sperm effect our oral-motor coordination? * Will this effect last long term? In general resisting the urge to masturbate does not cure or alleviate stuttering, nor does it give magic self confidence powers other than a placebo effect. Many times placebos only last a certain amount of time. If you want help with stuttering locate a speech-language pathologist who is familiar with stuttering and learn techniques to control your speech. It would be interesting to conduct a study, "The effects of long-term ejaculatory inhibition on speech disfluencies in adult persons who stutter" I can already tell you abstaining from masturbation does NOT alleviate or cure stuttering. But if to each their own..whatever strikes your fancy, blows your dress up, tickles your pickle (or lack there of) .
