emotional ties are said to have unrestricted sociosexuality. Individuals who are very unwilling to engage in sexual behavior without emotional ties are said to have restricted sociosexuality. Individuals can vary along a continuum from unrestricted to restricted sociosexuality. Community implications Couples with different styles of open marriage tend to self-segregate in order to find others who share similar philosophies and interests, which has likely contributed to the development of separate polyamory and swinging communities. These offer informational resources and support, even if a given couple in an open marriage cannot see themselves joining either community. Some couples may not have a strong preference for either style of open marriage, feeling equally at home either community. The partners within a couple may differ in their respective preferences. One partner may prefer a polyamorous style of open marriage and participate in the Polyamory community, while the other partner may prefer a swinging style of open marriage and participate in the swinging community. Variations in couple preferences and individual preferences thus can result in overlap between the polyamory and swinging communities. Lack of acceptance Christianity and other religions Some critics object to open marriages on the ground that open marriages violate religious principles. For example, open marriages contradict traditional Christian doctrine. Open marriages also violate the prohibition against adultery in the Ten Commandments. The definition of sexual immorality in Christianity includes the practices of open marriage and therefore it is considered an immutable reason for a dissolution of marriage. The Jewish religion hold similar values as Christianity in these matters. Muslims or Islamic teachings however allows for polygynous marriages albeit for the male partner only. Islam prohibits this practice for the female partner. The perceived validity of these objections depends entirely on individual faith. Arguments about faith and rationality lie outside the scope of this article. Generally, non-monogamous people tend not to be very religious. A 1998 review observed that, across the various studies, most swingers (approximately two-thirds) claimed to have no religious affiliation. Evidence of disapproval Surveys show consistently high disapproval of extramarital sex. Hunt mentions three general-population surveys conducted in the 1960s in which large majorities disapproved of extramarital sex under any conditions. More recent surveys show that 75–85 percent of adults in the United States disapprove of extramarital sex. Similar levels of disapproval are observed in other Western societies. Widmer, Treas, and Newcomb surveyed over 33,500 people in 24 nations
