American researchers from the Kinsey Institute for the Study of Sex, Gender and Reproduction provided information on how often people of a given age should have an intimate relationship. Scientists have named the optimal number of sexual acts per year for three different decades of a person's life: from 18 to 29, from 30 to 39, and from 40 to 49 years.
For adults who have not yet reached the age of 30, scientists call 119 sexual acts per year as the optimal amount of sex, that is, about two per week. As shown by another study conducted by experts at Wilkes University in Pennsylvania, such an amount of sex, in particular, in some way can help to strengthen the immune system.
Information about periods from 30 to 39 and from 40 to 49 years is not so much a recommendation as just an average result that can serve as a kind of benchmark. According to scientists, in these two decades, people on average have sex, respectively, having sex 86 and 69 times a year.
For an older age, statistics experts do not.
Although experts have looked at the sexual needs of people under the age of 50, a number of other studies conducted recently suggest that the need for intimacy persists for much longer. In particular, in July of this year, experts representing the University of Illinois at Chicago found out that interest in sex among people over 50 does not always decrease, and in some cases even increases. Scientists from the University of Cleveland later stated that women between the ages of 50 and 70 sometimes enjoy sex even more than 20-year-old girls, and experts from the North American Menopause Society concluded that the need for it does not disappear in women and after 70 years.
