Hah! I have a name which I have literally never heard a non-native speaker (of my first language) pronounce correctly.

As far as I understand it, the problem isn't so much that people haven't heard you pronounce your own name, it's more to do with the fact(?) that -- unless they've been raised in a similar "sound-environment" -- they literally cannot hear the subtleties of the pronunciation (e.g. tongue/lip positioning, etc.). I've had this experience (in reverse) when trying to pronounce Chinese and Arabic which have subleties which are very foreign to my native language.
