What Is That Red Dot on My Charmin?

I am not doctor, so in many ways I wish Dr. Colonic was writing this post, but I have a medical concern and I need to determine whether this is normal or just me.  First, to set the matter straight, I am a looker.  This means that when I wipe my butt after a solid doogan, I check out the toilet paper to see how much poo is up on there.  I like to determine whether I have cleaned sufficiently or not and I also enjoy the other information I get from the visual:  color, consistency, chunkiness, quantity, etc.  Well, nearly every time I wipe I notice there is a small little dab of blood on the toilet paper.  This issue goes way back to 2005 when I had diarrhea extremely bad.  The non-stop wiping and rawness and acid eventually caused my anus to have a little cut, or tear, or something.  That cut bled just a tiny bit…and has not stopped since then.
 
Now don’t get carried away and think that I’m gushing blood into my adult diapers each day.  It’s just a single, little dot that only shows up on toilet paper.  Here is what my imagination has come up with:  the cut can’t heal.  I live in humid environments and its an area that is almost always slightly moist…so how could it heal?  It’s not like I can stop taking craps and stop wiping for a week to let it heal properly  So the problem just perpetuates day after day after day.
 
I’m thinking about getting a maxi pad and lacing it with hydrocortisone cream or something to see if that can help the situation.  If you have or have had an anal cut like mine, I implore your wisdom!
