What are some potential causes of "wet flatulence"?

Anal incontinence. : When having loose stools and when having anal sphincter incontinence.

Diarrhea : It sounds like there may be a tendency to have diarrhea. I would advise you get evaluated for that possibility. There can be rectal leaking from other issues as well. Things to consider might be rectal inflammation, infection or a leaky cyst. You need to see your physician to get an evaluation.
