Prevalence of Non-Monogamy
§ Most research shows that approximately two-thirds of long-term male couples who have been together for five years or more are honestly non-monogamous (Shernoff,LCSW, 2007).
§ The prevalence of non-monogamy in gay male relationships became widely known as the result of the ground-breaking book, The Male Couple, David McWhirter,M.D. and Andre Mattison,PhD., 1984. Based on interviews of 156 long-term couples, they found that after 5 years, all of the couples had incorporated some provision for outside sexual activity.
§ Since the AIDS pandemic, four studies have found that gay men have not become more monogamous out of fear of HIV (Crawford, Rodden, Kippax & Van de Ven, 2001; Davidovich, et.al., 2001; Halkitis, Zade, Shrem & Marmor, 2004; LaSala, 2005).
§ Four studies document that only one third of male couples are sexually exclusive (Advocate Sex Poll, 2002; Bryant & Demian, 1994; LaSala,2004; Wagner, Remien& Carballo-Dieguez,2000).
§ One study contradicts these. 70% of men in male couples reported being monogamous and would view any outside sex as betrayal of commitment (Campbell,2000).
§ Multiple studies have found no significant differences in relationship quality or satisfaction between samples of sexually exclusive and non-exclusive male couples (Blasband & Peplau,1985; LaSala,2004,2005; Wagner,et.al.,2000).
§ Two studies found that both monogamous and self-described ‘open’ male couples demonstrated higher levels of relationship quality and lower levels of psychological distress compared with couples who had not negotiated nonmonogamy but reported covert outside sexual activity (Wagner, et.al,2000; LaSala, 2004).
§ Tangentially, a study on heterosexual relationships found that 24% of married men and 22% of married women had sex outside their marriages even though their spouse believed the relationship was sexually exclusive (Blumstein & Schwartz, 1983). (Of course,these numbers may have decreased as a result of the recent emphasis on family values). J
