Ever since I was a toddler I would regularly smell fecal residue on my crib bib/comfort blanket. For some reason I have always found the smell of feces up close to be uniquely gratifying.

Could this habit maintained over the course of many years have any possible negative health consequences? My mother asked my pediatrician when I was like 10 and he said that he was more concerned with me damaging my rectal tissue. Do you have any more insights?
