Abstract
Current modalities of sex therapy, consisting of both cognitive-behavioral and systemic approaches, show moderate results. Yet the very fact that such results are at times inconsistent or incomplete indicates that something is lacking in treatment. The present paper suggests that such inadequacies may be a result of a lack of focus on all aspects of sexuality as biopsychosocially determined within current modalities. The Sexological Systems Model proposes sexuality as a developmental process similar to Bronfenbrenner's Bioecological Systems Model. The Sexological Systems Diagram is introduced as an intervention for both assessment and psychoeducation for couples presenting for sex therapy. Information obtained through facilitating the Sexological Systems Diagram can be used by the therapist to determine the most appropriate treatment plan.
