When it comes to sex before marriage, a lot may be better than a little.
New research suggests that women who had exactly two sexual partners (their husbands and one other person) were more likely to divorce than those who had either just one partner or many more. This was true, at least, during the 1980s and 1990s.
Though it's not clear why exactly, the researcher speculated that women who had exactly two sexual partners were more apt to compare their husband to a past lover.
"In short: If you're going to have comparisons to your husband, it's best to have more than one," study author Nicholas Wolfinger, a professor in the University of Utah Department of Family and Consumer Studies and an adjunct professor in the university's Department of Sociology, said in a statement.

Changing sexual mores
Historically, the more sexual partners a woman had before marriage, the higher her odds of divorce, the researchers said. But sexual mores have changed dramatically in the last century.
To see if the changing attitudes toward premarital sex affected the risk of divorce, Wolfinger looked at data from three waves of the National Survey of Family Growth, a survey on marriage and sexual behavior. It was collected in 2002, between 2006 and 2010, and between 2011 and 2013.
The findings confirmed what many would believe by simply looking around: Women are much more likely to have premarital sex today than 50 years ago.
"Today's young adults do have lengthier sexual biographies than do people born prior to 1950," Wolfinger said. "Still, the extent of hooking up has been exaggerated by a prurient and overheated media, and sometimes by young people themselves." (Millennials actually have slightly fewer sexual partners than did those born in the 1950s and 1960s, research has found.)
About 21 percent of women who married in the 1970s had no prior sexual partners, whereas just 5 percent of women who married in the 2010s were virgins, the study found. Up until the 1980s, about half of brides had either married as virgins or had just one sexual partner (including their husband-to-be). By the 2010s, this proportion had dropped to 28 percent.
"In general, Americans became more accepting of nonmarital sex. Certainly, fewer men entered marriage with the expectation of a virgin bride. All of the fanfare associated with hooking up is evidence that some young people have become comfortable with the idea of sex outside of serious relationships."
Virginity and stability
Still, the study found that having more sexual partners was associated with reduced marital stability. Women who married as virgins were less likely to divorce within five years across all three waves of the study — just 11 percent in the 1980s and 6 percent in the 2010s.
But women who reported two sexual partners had the highest divorce rates in the 1980s and 1990s, the study found. For instance, in the 1980s, about 28 percent of these marriages dissolved within five years; by comparison, 18 percent of marriages ended when the women had more than 10 premarital sexual partners.
"Perhaps it is not unexpected that having many partners increases the odds of divorce. The greater surprise is that this only holds true in recent years. Previously, women with two partners prior to marriage had the highest divorce rates," Wolfinger said.
By the 2000s, women who had more than 10 sexual partners saw their marriages dissolve within five years almost 33 percent of the time, the study found.
