Married couples typically have sex about once a week on average. Various studies and surveys indicate that around 25% of married couples have sex once a week, with some having sex two to three times weekly, and others less frequently, such as once or a few times per month. About 10% of married people report not having sex in the past year. Research shows that couples tend to be happiest when having sex around once a week; having sex less often than that may correlate with lower relationship satisfaction, while having sex more often than once a week does not necessarily increase happiness. However, there is no "right" number of times couples should have sex. What matters most is what each couple mutually agrees is satisfying and healthy for their relationship. Frequency varies naturally with factors like age, health, lifestyle, and individual preferences. In summary:
- About 25% of married couples have sex once per week.
- Around 16% have sex two to three times a week.
- 19% have sex two to three times per month.
- A sexless marriage is generally defined as fewer than 10 times per year.
- Couples are often happiest with about one sexual encounter per week.
Ultimately, the ideal frequency is what works best for the couple and keeps them connected physically and emotionally.
