So this week I was shitting blood. When I wiped I realized, I had a lot of blood on the toilet sit. It was accompanied by some mild stomach pain, was pretty sure it was an ulcer. It went away eventually and my shits were blood free for years. About last week the blood came back. Like, a lot of blood. The water is more red than brown. I have zero pain though. I don't know what it could be but I'm a pretty healthy guy. I was looking at this site at shittingblood it provided me with some good information.
