You have taken the first step towards your treatment by actually seeking advice. Now that you have started, the way forward can only get better. There is hope and success will be achieved with therapy. There is no doubt that you have to consult a specialist who deals with behavioural problems, or bluntly speaking, a psychiatrist. I have consulted my colleagues and they feel the same. Since this is a form of addiction you will have to go through a deaddiction therapy which might include drugs, behaviour modification and psychotherapy which are called the twelve step programme. You may not have to think of extreme steps like clitoridectomy. Infibulation may not help at all and should be avoided for other more serious reasons.
