From the early 1990s into the early 2000s, Americans generally had sex from about 60 to 65 times a year, according to the study. But after 2002, Americans appeared to lose interest. While the decline has been nearly across the board, one group seems to be pulling everyone else down: married couples.
Married couples had sex an average of 56 times a year in 2014, down from 67 in 1989. But more people are staying single — meaning there is less sex — and the couples who do walk down the aisle are making fewer trips into the bedroom.
Despite all the declines, one age group showed no interest in slowing down: people over 70. They had sex nearly 11 times during 2014, up from an average of 9.6 times in 1989.

People in their 20s have sex more than 80 times per year, declining to 60 times per year by age 45, and 20 times per year by age 65. Each year after the peak of sexual frequency at 25, sexual frequency declines 3.2 percent.
