I don't want to scare you but any time symptoms have possibilities of being either a minor or serious concern, you need to have a doctor look at it. There's a lot going on in the background down there and the itching is your body's way of telling you something is not normal. Don't panic, just make an appointment and find out exactly what it is. The only thing anybody here can do is guess what it might be.
