Help Getting Rid of Mental Block

[justme]

Has anyone successfully gotten past their mental block when it comes to sneezing?  I've sneezed in front of others maybe twice in the past ten years.  When I'm alone, I'll let them out, but I'll stifle them completely.   I literally have not let out an unstifled sneeze since hitting puberty and discovering my fetish.  I don't even know what my real sneeze sounds like!  

The thing is, I don't want this mental block anymore.  Lots of people in this community seem to enjoy their own sneezes, which sounds great to me. I want to embrace my natural sneeze.  But I cannot prevent myself from stifling--it's automatic.

Any tips on getting rid of the mental block?
