After any kind of bowel movement, I find that in about an hour or two later, I get a wet feeling in the back. The frontal area is dry, but it's like some sort of liquid fecal matter is somehow appearing after a bowel movement. I don't know if it's sweat, but there is a signature brown color and odor to the substance. I'm 17, female, with no history of cancers, bowel or gastrointestinal disorders, or pregnancy.
