Chapter 16, entitled "Love Without Jealousy", devoted 20 pages to the proposition that an open marriage might possibly include some forms of sexuality with other partners. Blumstein and Schwartz note a slightly higher risk of divorce among couples who engage in extramarital sex, even if the couples agree to allow extramarital sex.[16] However, Rubin and Adams did not observe any significant difference in the risk of divorce for couples in open marriages and couples in sexually monogamous marriages.[17] Couples who prefer extramarital relationships emphasizing love and emotional involvement have a polyamorous style of open marriage. Couples who prefer extramarital relationships emphasizing sexual gratification and recreational friendships have a swinging style of open marriage. A polyamorous style of open marriage emphasizes the expansion of loving relationships by developing emotional attachments to extramarital partners. ./cache/en-wikipedia-org-5986.html ./txt/en-wikipedia-org-5986.txt
