Marital alternatives and the regulation of sex

The relationship between the occurrence of extramarital affairs (as an indicator of the reduction of normative constraints) and commuter marriage (as an indicator of the reduction of structural constraints) was examined. It was found that when couples set up two separate homes they were not more likely to have affairs than when they shared a single home (or that the reduction of structural constraints does not necessarily lead to the reduction of normative constraints). In contrast to other studies that stress opportunity as a key factor in the occurrence of extramarital affairs, this study suggests that attitudes toward affairs are neither enforced nor weakened by opportunity. Two underlying orientations to marriage, which exist simultaneously in different segments of the population, were uncovered: one involving an attachment to the family as institution and one involving an attachment to the family as companionship.
