Unless you have someone you trust enough to look in that area. I would suggest seeing your doctor. Perhaps a stool analysis may be needed as well. I would use a moist warm wash cloth to wipe the area, there may be toilet paper being left behind which causes irritation and then may cause the funny feeling. But if you have pin worms or something in that nature, you can get medication from your doctor. But without knowing the exact cause makes it hard to tell you what to try.
