Associations Between Premarital Factors and First-Married, Heterosexual Newlywed Couples' Frequency of Sex and Sexual Satisfaction Trajectories.

Sex is a defining feature of marriage with important implications for marital success. Nevertheless, frequency and quality of sex decline across the early years of marriage. Given many modern-day couples in the U.S. are delaying marriage and thus experiencing many traditional aspects of marriage before their nuptials, the current research explored the extent to which premarital factors such as courtship duration, cohabitation, and children are associated with trajectories of couples' sexual relationships during the early years of marriage. Using a 4-year longitudinal study of newlywed couples, results demonstrated that couples with longer (versus shorter) courtships or who did (versus did not) cohabit engaged in less frequent sex at the start of marriage; interestingly, couples with longer (versus shorter) courtships or with (versus without) children prior to marriage experienced less steep declines in frequency of sex over time. Couples who did (versus did not) cohabit were less sexually satisfied initially and over time; couples with longer (versus shorter) courtships experienced less steep declines in sexual satisfaction over time. Notably, each of these associations emerged independent of related individual differences and marital quality. These findings highlight the notion that premarital factors can explain, at least in part, differences in newlywed couples' sexual relationships.
