Good evening and thank you for the opportunity to help in answering your question. First please allow me to say that I am sincerely XXXXX XXXXX hear of the pain and difficulty you're going through right now. Based on the information you've kindly provided in your question...it's entirely likely that his sexual addiction is due in part of an anxiety disorder, namely Obsessive Compulsive Disorder.
There are specialists around the country who treat these specific types of conditions though in my experience it would also serve your husband well to see a therapist that is experienced and trained in Cognitive Behavioral Therapy as this is the approach most commonly used. Essentially, the approach explores further into one's thoughts and triggers and prompts that bring them and then at the resulting behaviors.
You can contact your health insurance provider in order to get a referral to see a therapist. There is also the option of medication therapy though I would strongly recommend that your husband sees a psychiatrist to be started on the most appropriate of medications. The two most effective would be Prozac and Paxil as both are effective in the treatment of OCD.
Finally, I would like to offer you a link to a workbook that is concentrated on sexual disorders and the exercises found in the book are based on Cognitive Behavioral Therapy as I noted above.
