I am 25 years old female. I have stammering problem from class 5.Not heavy stammering. My mother tells me I am not a stammer just its my style of talking. I personally feel that I am not stammer because I can speak normally except repeating few syllables sometimes. I wonder whether it's hormonal or not. Because I have the habit of masturbating since childhood. I noticed that whenever I masturbate I can't say a single word. After 3-4 days it starts to normalise. My vitamin D was low at 10 last year and B12 290. Stammering can be cured 100%.How? Please help.
