Using data from the National Survey of Family Growth, we find that men who were virgins when they entered marriage had a divorce rate of 4%. If they had only had premarital sex with their engaged partner, their chance of divorce was 16%. The divorce rate increases as the number of partners increases.

The divorce rate for male virgins is actually 10% lower than it is for female virgins, and the correlation between premarital sex partners and divorce is slightly stronger for men than it is for women.

There are two similar studies that have been posted on the sub recently.

Results indicated no significant relationship between the experience of premarital sexual intercourse and marital satisfaction of men or women. However, men, who had more premarital partners and cohabitation experience, were less satisfied with their marriages. For women, younger onset of sexual activity and larger number of premarital partners was related to lower marital satisfaction.

Characteristics of premarital conduct such as age at sexual debut, length of acquaintance with debut partner and number of premarital partners were significantly associated with EMI (extramarital intercourse) in men later in life.

So can we put this one to bed? Premarital sex correlates with marriage difficulty for men AND women across cultures.
