According to a study published in the journal JAMA Network Open, the number of sex lives in the u.S. has dropped significantly since 2000, with nearly a third reporting that they have not had sex with a partner in the past year. The study excluded two possible factors, pornography and long working hours, and suggested that the possible reasons for the decline in the frequency of sex include the pressures of modern reconciliation of life and work, the popularity of social media and online games.
The study analyzed data from a two-year survey of nearly 10,000 men and women between the ages of 18 and 44 between 2000 and 2018 and found that 16.5 percent reported having less sex between 2016 and 2018, compared with 9.5 percent in 2000-2002.
In 2016-2018, 30.9% of 18-24-year-old S18-24 men reported having no sex in the past year, compared with 18.9% in 2000-2002.
There is also an increase in the inactivity of sexual activity among men and women between the ages of 25 and 34. In a commentary, Jean Twenge of the Department of Psychology at San Diego State University argues that people have more choices to do at night than before, and that if both men and women are addicted to social media or video games, they are less likely to have sexual activity.
