Married couples typically have sex about once a week on average. Studies show that:

• About 25% of married couples have sex once a week, 16% two to three times per week, and 5% four or more times per week

• Another study found the average American married couple has sex roughly 56 times a year, which is about once a week

• Research suggests couples who have sex once a week tend to report the highest levels of happiness in their relationship; having sex less frequently correlates with lower happiness, but having sex more often than once a week does not necessarily increase happiness further

Sex frequency varies by age, with younger couples generally having sex more often than older couples. For example, people over 50 tend to have sex a few times a month or less, and frequency often declines with age

. There is no "normal" or ideal frequency that fits all couples. What matters most is that the couple mutually agrees on a frequency that satisfies both partners. Sexual satisfaction and intimacy quality are more important than hitting a specific number

. In summary, once a week is a common baseline frequency for married couples, but individual preferences and life circumstances can lead to wide variation. The key is that both partners feel satisfied and connected
