The frequency with which people have sex varies widely based on age, relationship status, health, stress, and individual libido, but on average, couples tend to have sex about once a week.

• Adults in their 20s typically have sex more frequently, about 80 to 112 times per year, which is roughly once every four to five days

. This is linked to higher testosterone levels and generally higher sex drives in younger adults

• For adults aged 25 to 44, about 50% report having sex at least once per week

. Studies show that the median sexual frequency for married or cohabiting couples is around three times per month, though many couples report once or twice a week

• As people age, sexual frequency tends to decline. By the mid-40s, it drops to about 60 times per year (just over once a week), and by age 65, it may be around 20 times per year or less than once every two weeks

• There is no universally "normal" or ideal frequency. The quality of the sexual relationship, mutual satisfaction, and emotional intimacy are more important than hitting a specific number

• Some couples, especially those without children, may have sex more or less frequently depending on their preferences and circumstances. For example, some long-term couples report having sex a few times a week, while others may have sex once a month or less and still consider their sex life healthy if both partners are satisfied

In summary, while the average is about once a week, healthy sexual frequency varies greatly among individuals and couples, with mutual satisfaction and communication being key factors.
