If what you are saying is true, KenP, then I believe DRTYFN needs to be treated for sexual addiction, along with other therapy.
The initial therapeutic intervention for sexual addiction needs to include an assessment for other addictions. It is impossible to expect treatment for one addiction to be beneficial when other addictions co-exist.
The behavior of sex addicts has profound effects on partners, children, parents and siblings. The addict is usually partially or totally unaware that their behavior has affected their loved ones. Families develop unhealthy coping skills as they strive to adapt to the addict's shifting moods and behavior. Curiously some addicts may act out in solo isolating behaviors leading to feelings of family abandonment. For these reasons, friends and families will often need to be involved in the recovery process.
Those who do not attend 12-step meetings have a much more difficult time recovering, if they do at all. In many ways recovery from significant sexual addiction can be more difficult than recovering from some of the other addictions. The heavy prevalence of sexual abuse in the backgrounds of sex addicts is one reason. In addition, sexual addiction fundamentally involves a problem with intimacy, something important for successful recovery.
Self-help groups such as Sex Addicts Anonymous, Sexaholics Anonymous, and Sex and Love Addicts Anonymous are popular with proponents of the sexual addiction concept. These are large groups based on the 12-step system of Alcoholics Anonymous. There are various online support forums as well as real-life help through an out- or in-patient program or private counsellor. Some intensive programs work with both the addict and the addict's partner.

Therapists also use cognitive-behavioral therapy, and medications may be of value particularly in overcoming conditions or disorders that lead to increased acting out.
It is important to distinguish between sexual addiction and sexual anorexia not related to sexual addiction, as both can present similar behaviors, but effective treatment may be quite different. Aside from depression, it also must be established whether or not the presenting behaviors are due to obsessive-compulsive disorders, bipolar disorders, etc.
It is highly imperative the addict finds an experienced, trained counsellor to help with their addiction. Addicts suffering from other disorders in addition to sexual addiction (Narcissistic Personality Disorder, Borderline Personality Disorder, etc.) rarely reach and maintain a sober recovery without highly trained assistance.
Supposedly, the longer a sex addict has been acting out and the higher the level an addict they are, the lower the chances of a successful, sober recovery being maintained. Unless a sexual addict hits bottom (much like a drug addict) they will rarely seek recovery on their own. Other related, untreated psychological conditions or disorders can also reduce the chances of the addict maintaining a sober recovery.
It is also important that the partner of a sexual addict seek their own, individual counselling to help them learn how to deal with their partner's addiction. There are also online support groups in addition to real-life help.
