I would encourage you to see a health care professional with something like this that could range from simple hemorrhoids to something far more serious.
My first choice would be a naturopathic doctor (N.D.), or an MD or chiropractor who practices holistic health. A colon hydrotherapist can assess the condition of your anus and rectum to see if it is just superficial veins bleeding as badcattoe mentions, or perhaps something higher up that needs urgent attention.
Please don't wait on seeing someone about this. Better safe than sorry.
