Being a BBW you probably wouldn't put me in the same category as the providers you are anxious about seeing, however as a provider, for me anyway, how you look wether it's race, or just physical appearance really doesn't matter to me.
My first concern is that you are a nice, thoughtful person I can make a connection with, second that you practice good hygiene and a distant third is how intelligent are you.
I think if you treat any provider with respect, you will get the same back to you!
Good luck with your new pooning adventures ahead!
