I get where you’re coming from. I was always really self conscious about my stutter while going on dates. What’s helped me is not being shy about the fact that I stutter. I usually let the person know that I have a speech impediment right away. Many times the person will be supportive and that should help ease your worries. Try not to let your anxiety get in the way of you moving forward with dates. The more you put yourself out there with someone, the more comfortable you’ll become with that person. Eventually causing your anxiety to slowly decrease.
