The relationship between gender role and marital instability: The role of moderating sexual orientation in men

The aim of this study was to determine the moderating role of orientation in men's sexual relationship with marital instability. The method of the present study is correlational. The statistical population of the study was men living in Tehran who had lived together for at least one year. Thus, 150 people were selected by available sampling method from different parts of Tehran by referring to public places and distributing a questionnaire in cyberspace. Measurement tools in this study included MII Marriage Instability Questionnaire, BSRI Gender Maps and SRS Sexual Orientation. The results showed that sexual orientation has a moderating role in the relationship between gender roles and marital instability. High levels of participatory sexual orientation reduce marital instability. The high exchange rate of sexual intercourse increases the instability of marriage in men. Also, in the direction of expectation in sexual intercourse, its increase leads to an increase in marital instability in men. In men with high expectations of exchange, exchange, and expectation in sex, increased gender roles reduce instability; But in men with low participatory and exchange orientations, increased gender roles do not change the degree of marital instability.
