For about 3 months now I have been itching around my anal area. It's not everyday and it's mainly when I wipe or wash. Sometimes when I wipe or wash it itches so bad I feel like digging at it with the wash cloth. It itches extremely bad at these times. I don't see any signs of worms and I haven't been using any new products. I've never been sensitive to any products anyway. What could this be? I am married and not really sexually active if that matters.
