Im sorry to see that this is so old, but im thankful i found it. I thought it must just be me. Not only do i eat scabs, blackheads and anything else i can find, i love certain smells. Im a compulsive overeater also, so i am a very heavy woman. If i dont take a shower for a few days, i get that smelly yeasty paste and i like to get it on my hands and smell it. It sounds as totally crazy when i write about as it does when i think about it! I dont know if this blog is totally dead, but im so glad to find others like me.
