This compares with the average adults enjoying sex 54 times a year or just over once a week.
But most interestingly, the research showed a drop in recent years compared to between 2000 and 2004, in fact nine few times per year.

Other older research backs up these states: findings by the University of Chicago Study called “The Social Organisation of Sexuality: Sexual Practices in the United States,” showed that nearly only a third of couples have sex two or three times week while half are saying they have sex a few times a month.
