What did Willoughby et al. (2013) find about the timing of sex in relationships?

• A. Early sex always leads to higher satisfaction.
• B. Waiting longer reduces satisfaction.
• C. There is no meaningful difference in relationship satisfaction between early and late sex.
• D. Sex timing has no relation to relationship closeness.

Answer: (C)

The main idea is that when couples have sex in a dating relationship does not meaningfully change how satisfied they are with the relationship. Willoughby and colleagues tracked dating couples over time and compared those who had sex early with those who waited longer. The findings showed that satisfaction levels were similar across early and late sex groups, with differences being small and not statistically meaningful. In other words, timing of sexual initiation isn’t a reliable predictor of relationship satisfaction. This helps counter ideas that having sex sooner automatically boosts happiness or that waiting longer harms it. The study points to other relationship factors—like communication, compatibility, and trust—as more influential for satisfaction than when sex first occurs.
