35/m.i usually get mucus in my stool.rarely lil red blood thread in clear mucus.my bm-1/2 a day.not dark.no constipatn or diarrea.no pain,mild dscomfrt below naval zone.gas relieves.stool-semi solid.has a feeling like diarrea but not really. ca sym?

Probably not: Some amount of mucus is normal in stools but significant amount with pain , diarrhoea or blood would indicate inflammation or infection in intestine. These symptoms could be caused by parasite in intestine, irritable bowel syndrome, Crohn's disease , ulcerative colitis and sometimes by cancer too . Consult your doctor to confirm the diagnosis.

Colitis?: Cancer is unlikely with these symptoms, especially at your age. In your part of the world, parasitic infections are frequent, e.g. mild chronic amebic dystentery and others. Inflammatory bowel disease is possible. STDs can do this when the rectum has been exposed, especially in men who have sex with men. See a doctor, and expect referral to a gastroenterologist for colonoscopy. Good luck!
