But when you look specifically at sex itself, at patterns of actual sexual activity and their link to marital happiness and longevity, direct evidence for a permissiveness premium is extremely hard to find. And for women, almost all the the data points sharply in the opposite direction. Notwithstanding the potential for regrets, women who only had sex with their future spouse are more likely to be in a high quality marriage than women who had a higher number of sexual partners. Divorce rates are higher for women with multiple premarital partners than women who had only one; they’retwice as high for women who have cohabitated serially than women who only cohabitated with their future husband. Independent of marriage, relationship stability is stronger when sex is initiated later, and monogamy and a restricted number of sex partners isstrongly associated with female happiness and emotional well-being, period. And these results hold irrespective of education levels, as this piece by Brad Wilcox and Nicholas Wolfinger points out: There’s a stronger correlation between multiple premarital partners and marital instability among less-educated Americans, but well-educated Americans, too, show much stronger marital outcomes when they have fewer premarital partners. (And interestingly, the usual connection between education and stability disappears entirely for people who married their first partner: They’re equally unlikely to divorce no matter whether they attended college or not.)
