Thank you for the added information. It helps a lot. I believe I can now be of help with this issue.
First, let me say I can imagine how distressing this situation must be for you. That this problem began at that definite date is really pointing to an anxiety disorder. That you wife all of a sudden had an affair a few months later seems related.
And this is actually the key to my answer to you that you need to consider and think about. First of all, you can try to deal with the symptoms themselves. But I'm not convinced that you're going to be happy with the results necessarily. One method is to take testosterone lowering medications. But those may have unpredictable results wherein your sex drive is eliminated. So you may not want to mess with them. Another way is with antidepressants. They are sometimes used for premature ejaculation because they weaken sexual drive. They may work to lower your sex drive as well. Antidepressants do have side effects, especially with extended use. But this is an option you can discuss with your doctor.
Okay. Those are the pharmacological options you can consider. But they are not great choices in and of themselves. The psychological option sounds more promising but it has the drawback of being slower in effect. There are three approaches to therapy you might consider.
The first is to treat this as a symptom of an anxiety disorder. It's not clear what the trigger was 1.5 years ago for the anxiety disorder but it led to dysfunction in the marriage which then has led to ongoing dysfunction in your relationship with your wife which is manifesting in this hypersexual behavior. This would be treated with Cognitive Behavioral Therapy.
You might find that this approach is too superficial, focusing too much on the behavior and not enough on your emotions of hurt, disappointment, betrayal, etc. This would mean working in a more psychodynamic and/or humanistic therapy to find the source of the emotions that are expressing themselves through anxiety and hypersexuality.
If you don't have a good referral source for yourself, here is the web address for Psychology Today's therapist directory. You can sort by zip codes and when you see someone who seems like they might be helpful (you can see a photo of the therapist!) look at the listing and see if they list CBT, psychodynamic, and/or humanistic psychotherapy in their orientations, or a combination of these.
Another approach is to treat this as a relationship problem in your marriage and to go to couples therapy with your wife. One type of therapy is called Emotionally Focused Couples Therapy. This one is the one I would use in your situation first. Why? Because it focuses on how there have been created emotional barriers and how to get through those barriers. Please consider it before you take other action. Here is the web address for their therapist finder:
On the website you'll also find excellent books by the founders, Sue Johnson and Leslie Greenberg. You may not find an EFT therapist in your area, though, so you might have to seek someone from the Psychology Today directory that seems experienced.
Clearly there is an emotional divide you are feeling with your wife and you are both trying to bridge it with sex and punish her with sex. The psychological aspect of this seems very clear. The doctors' reports seem to confirm this. These three options are your best way to approach it. My recommendation would be to try the couples therapy first to see if you can move closer emotionally to your wife and if the hypersexuality will ease up as you two learn to be more emotionally intimate instead of sexually intimate.
I wish you the very best!
