OMG - Astrid! I have exactly the same problem. It started when I used a hair removal cream down there and gave myself a chemical burn when I was younger . - TMI sorry

Now it can be so itchy it is unbearable. At the moment 1% dermaid is working well but I have to change products all the time to keep some relief. Problem is that every time I have to see a Dr - I can't always see the same one at the clinic and each one wants to give me a full STD check!! I have been tested so many times now its not funny!!
