I can't find the source but I remember reading about stuttering on your own name started with unwillingness to reveal who you are, because ... who you are is you are a stutterer. You don't want the world to know this because ... in the past, people have laughed at you. Thus begins the stutter pathway: you stutter on your own name (or your phone number or your home address) for the first time, the experience is traumatic, yet your brain tells you to stutter again on the same word the next time. Compounded by the fact that your name/number/address are fixed ... you can't substitute them with another word like what you do with non-personal words on which you stutter. My memory may be faulty, but it's more or less like that. Try introducing yourself in a crowded bar or a loud environment where you can't hear yourself. I bet you won't stutter. Or use a pair of earbuds. Don't damage your ears, though ... it is bad enough you stutter. Or sing your name. If they look at you funny ... \_*what .... doesn't everyone sing their name?*\_ . Oh well, they look at you funny anyway. No difference.
