A new study of moms with young children, conducted jointly by Cookie, the lifestyle magazine for the modern mom, and AOL Body, reveals that 34 percent of moms report having had an affair since having children, and 48 percent suspect their husbands have had or are having an affair.  The survey, entitled “Sex and the American Mom,” polled a nationwide group of more than 30,000 mothers with at least one child. The poll was conducted entirely online at cookiemag.com and AOL Body.  “The somewhat startling statistics invite a closer look at the state of sex and the American marriage. As a magazine for moms who are trying to have it all and keep it all together, we are trying to get at the problems of marriage, which often play out in the bedroom,” said Pilar Guzman, Editor-In-Chief of Cookie.
