The ultimate infidelity: Cheating in the marital bed

In an informal, unscientific survey conducted at the request of The New York Times by the Web site CafeMom.com, which draws young married women, more than half of approximately 500 respondents said their marriages would “definitely not” survive if their partner made love to another person in the marriage bed. By contrast, less than a third of approximately 700 respondents to another question said that their marriages would “definitely not” survive an affair outside the home.

“It would hurt no matter where it happened,” one anonymous respondent wrote. But “if he did it in my own home,” she added, “it would feel more like a slap in the face.”

Few marriages survive such an affair — and even fewer marriage beds.
