Thanks for your testimony, BeardedLooper. I noticed that staying away for masturbation and porn helps me a lot too. After a period of abstinence, my speech gets more fluent, I'm more confident and happy and I have less fear to join in conversations. It might not work for every stutterer, but I can guarantee that it worked for me. You should see a significant improvement in your speech after about 2 weeks (not before). I think it's really worth it.
