Defining invested partners as sexually asymptomatic male and female partners of sexually dysfunctional men and women, the authors attempted to determine whether any psychological problems, separate from sexual dysfunction, existed in the invested partner. They used a self-administered symptom inventory. The male invested partner, although sexually asymptomatic, showed a much higher psychological distress level than did the female invested partner, about the same level of distress as the male sexually dysfunctional partner. The authors conjecture that this difference has to do with cultural factors that determine the male's supposed role as sexual aggressor and sexual satisfier.
