Yes I stutter on my first and last name as well. My last name is pretty long Rodriguez and I rarely ever get it out without stuttering. Though if I say it slow I can usually get it out. My first name i sometimes use a shorten version cause it’s one syllable so it’s easier for me to say. I almost always stutter if I say my full name though same as my last if I say it slow I can get it out. Sometimes if I’m on my phone and stutter I always say I can spell it for you if you didn’t understand. Majority of the time they say no that’s okay we got it. I never feel ashamed about my stuttering anymore tbh it’s just a part of me and I accepted it.
