Blood on toilet paper occasionally about thirty minutes after using restroom. It itches and feels wet, seems to happen more when I'm active. Thank you?

Hemorrhoids. Intermittent blood on the toilet paper is often due to a small amount of bleeding from internal hemorrhoids. Blood on the stool or in the bowl may be due to other causes and should be evaluated. Persistent blood on the paper is likely benign but should be evaluated. See http://wb.md/1Jj80zo.
