Marriage and Sex

Adults Have Sex 61 Times a Year

Adults, on average, have sex about 61 times per year, or slightly more than once a week, according to University of Chicago's National Opinion Research Center. Marital status and age are key influences in sexual activity.

Sexual activity is 25 percent to 300 percent greater for married couples versus the non-married, depending on age. The 1998 University of Chicago report that compiled available sex research also concluded that intercourse is more frequent among couples in happier marriages.
