Why Am I Seeing Bright Red Blood After Bowel Movements?

I usually have bowel movements once per day. This remains the same yet on Sunday I saw bright red blood on the toilet paper after wiping my bottom. It took several wipes for the blood to clear away. Each wipe had marginally less blood. All in all I wiped away around two tablespoons of bright red blood. I checked my stool and the bright red blood was intermixed with the stool. It stained the inside of the toilet with bright red streaks of blood as it caught the inside edge of the toilet basin. Aside the blood in the stool, there was no other blood pooled at the bottom of the toilet water. This has happened each day since. There is only blood during bowel movement. I don't have constipation and don't need to strain to defecate. The stool is of a normal size, colour and consistency. Neither big nor hard to cause an anal fissure on exit. I have no pain, no constipation, no itchy bottom, no fatigue, no lightheadedness, no fever, no unintended weight loss. I am a man aged 40 with no other health complaints.
