Abstract:
This study examined the marriages of 26 couples in which the husband was bisexual. The subjects were a non-clinical sample married for at least two years and intending to continue their marriages. The sample was, overall, highly educated and earned concomitantly high incomes. Subjects were administered the Klein Sexual Orientation Grid and a research questionnaire to determine successful or problematic aspects of their marriages. Subjects were, for the most part, satisfied with the quality of their marriages, sexually active within the marriages, and open about the husband's homosexual behavior. A high-level of sexual activity within the marriage, open and direct communication, a valued friendship, previous counseling or psychotherapy, cognitive flexibility, and financial independence contributed to the success of these marriages. The husbands reported a great deal of ambiguity about their homosexual behavior, and the couples reported intense conflict dealing with their open marriage styles.
