The fundamental of behavior therapy is that all the behaviors are learned, even the maladaptive behaviors. The behavior therapist helps the client to unlearn the Un adaptive behavior and replaces it with newly learned adaptive behavior. The aims of behavior therapy are primarily educational and the techniques facilitate improved self-control. From amongst several techniques that are used in behavior therapy, ‘systematic desensitization technique’ is used in sex therapy. Prior to 1970 sexual dysfunctions were managed by psychiatrists. After 1970, the Masters & amp; Johson model of sex therapy made it possible to treat sexual dysfunctions by psychologists, social workers, nurse, counsellors, and medical doctors. Their approach included: Instead of treating the affected individual, the couple is treated. It is the relationship that is affected. This strategy provides an opportunity to gain the co-operation and understanding of both the partners in overcoming the problem. Two therapist- a man and woman work together
