Stop masturbating, stop watching porn, give your life to Jesus Christ and get yourself a New KING James Version Bible NKJV and read the whole new testament and the old testament. "For He was wounded for our transgressions, the chastisement of our peace was upon Him and by His stripes we are healed." Isaiah Ch. 53. Jesus Christ can heal you, He is the one true God. Put your faith in Him. Go and sin no more. I noticed when I stopped watching porn, stopped masturbating and gave my life to the Lord Jesus Christ, and incorporated more exercise and healthy eating, stuttering subsided.
