Another study, this one sponsored by The National Marriage Project at the University of Virginia, stated, “In our sample, only 23 percent of the individuals who got married over the course of the study had had sex solely with the person they married. That minority of men and women reported higher marital quality than those who had had sex with other partners prior to marriage. We further found that the more sexual partners a woman had had before marriage, the less happy she reported her marriage to be.”
