I think your afraid to get out of your comfort zone and are in denial--we are terrible speakers. To be an effective speaker, including those who don't stutter, takes practice. Stutterers are behind the curb we speak less than a normal person so we must speak more and get better at the art of speaking. Whats the longest 1 on 1 conversation you had a person unrelated to you in the past year? If you were drinking alcohol it doesn't count.
