Couples should ideally have sex as often as feels mutually satisfying to both partners, as there is no universally "right" number of times. However, research and sex therapists frequently cite about once a week as a common frequency associated with higher relationship satisfaction and happiness. Some key points from studies and expert opinions are:
- About 25% of married couples have sex once a week; some have more or less frequently, with ranges spanning from multiple times a week to a few times a month or less.
- A 2015 study found couples reported the highest happiness when having sex about once a week. More frequent sex did not significantly increase happiness beyond that level.
- Sex therapists often recommend couples try to have sex about once a week while emphasizing that frequency should be based on each couple's individual needs and desires.
- Having less than 10 times a year (less than once a month) is sometimes called a "sexless marriage," but this label and its impact vary greatly depending on the couple's satisfaction.
- Quality and mutual satisfaction of the sexual relationship matter more than a specific frequency number. Some couples are content with less frequent sex and others with more.
In summary, while the "magic number" often suggested is around once a week for sustained sexual well-being and relationship happiness, the frequency should ultimately be what works best for the couple's unique preferences and circumstances.
