If you don't mind me to disagree on the relevance between stutter and pornography I'd say I can't detect any differences between my stuttering at the beginning of consuming pornography and stuttering after finishing comsuptions so I can't figure out why it can be considered as the wire-puller just bc it can secrete dopamines. There are way more other things that can secrete dopamines but is it true that all of them can deteriorate your stuttering, like CocaCola, COD, Youtube and etc. Moreover, the effects of secreted dopamines from pornography are not permanently, maybe just lasting for dozens of mintues and that's all, but adult stutter is obviously a lifelong disorder if your speech system cannot develop compensatively as you age while the effects are not lifelong with the stuttering.
