Single adults have sex far less often than most people assume. A large share report no sex at all in a given year, and the numbers have been trending downward. Among unmarried men aged 18 to 44, nearly one in four reported no sexual activity in the past year as of 2016-2018, up from about one in six just a few years earlier. For those who are sexually active, frequency ranges widely, from a handful of times per year to weekly or more.
What the Numbers Actually Look Like
National survey data from the U.S. breaks sexual frequency into four broad categories: no sex in the past year, once or twice per year, one to three times per month, and weekly or more. Single people are spread across all four groups, but a disproportionate number land in the lower categories compared to people in relationships.
The clearest snapshot comes from adults aged 18 to 44. In the 2016-2018 survey period, 30.9% of men and 19.1% of women aged 18 to 24 reported zero sex in the past year. Among 25- to 34-year-olds, 14.1% of men and 12.6% of women were sexually inactive. By ages 35 to 44, the rates were roughly equal at about 8% for both men and women. These figures include both single and partnered people, but the researchers found that the rise in sexual inactivity was concentrated among unmarried individuals, particularly unmarried men.
For single people who are having sex, “once or twice per year” and “one to three times per month” are the most common frequency ranges. Weekly sex is possible while single, of course, but it typically requires either a consistent casual partner or active dating life, making it less common than for couples who share a bed.
The Gap Between Single Men and Single Women
One consistent finding across surveys is that single men report less sexual activity than single women. In the 18-to-24 age group, the gap is striking: roughly 31% of young men had no sex in the past year compared to 19% of young women. That 12-percentage-point difference narrows with age but persists into the mid-30s.
Several factors explain this. Women in this age group are more likely to have partners who are slightly older, pulling from a wider dating pool. A smaller number of men may account for a larger share of sexual encounters with multiple women. And survey data consistently shows that young men are more likely to be unpartnered overall, which naturally limits opportunity.
Single People Are Having Less Sex Than Before
The so-called “sex recession” is real, and it hits single people hardest. Among unmarried men, the share reporting no sex in the past year jumped from 16.2% to 24.4% over the study period, a roughly 50% increase. This trend held even after adjusting for factors like age, race, and education.
The reasons are layered. More young adults are living with parents, which limits privacy. Screen time and dating apps have changed how people meet, sometimes replacing in-person socializing with passive scrolling. Economic pressures, including student debt and housing costs, delay the milestones that historically led to sexual partnerships, like moving out, dating regularly, and cohabiting. The rise of remote work and declining participation in religious and community organizations have also reduced the casual social contact that once led to relationships.
It’s worth noting this trend predates the COVID-19 pandemic. The data showing the sharpest declines comes from 2016-2018, suggesting these are structural shifts in how single adults live rather than a temporary disruption.
How Singles Compare to Coupled People
The frequency gap between single and partnered adults is significant. People in relationships have a built-in advantage: proximity and routine. A Norwegian study of over 4,000 adults found that 97.3% of partnered people had experience with intercourse, compared to 85.6% of single people. That 14.4% of single adults who had never had intercourse represents a meaningful group that doesn’t exist in the same way among coupled people.
For sexually active singles, the comparison is less dramatic but still notable. Partnered adults most commonly report sex one to three times per month or weekly, while sexually active singles tend to cluster in the lower frequency ranges. The difference isn’t just about desire. It’s about logistics. Having a willing partner in your home removes the biggest barrier to sexual frequency.
What Shapes How Often Singles Have Sex
Age is the most obvious factor. Sexual inactivity peaks in the youngest adult group (18 to 24), drops through the late 20s and 30s, and then begins rising again after 50 as health issues and a shrinking dating pool come into play. The low point for sexual inactivity, around 8%, occurs in the 35-to-44 range, likely because people in that bracket who are single tend to be divorced or between long-term relationships rather than never-partnered.
Geography and social environment matter too. People living in dense urban areas with active social scenes and larger dating pools tend to report more sexual activity than those in rural or suburban settings. Employment status, mental health, and physical health all play roles. Depression and anxiety reduce sex drive directly and also make it harder to pursue new partners. Chronic stress has a similar dampening effect on both desire and opportunity.
Alcohol and social habits also factor in. A significant share of casual sexual encounters among single people happen in social drinking contexts. As young adults drink less than previous generations (a well-documented trend), one traditional pathway to casual sex has become less common.
What “Normal” Actually Means Here
If you’re single and wondering whether your sex life is typical, the honest answer is that “typical” covers an enormous range. Roughly one in five to one in four single adults in their 20s has no sex in a given year. Among those who do, anything from a few times per year to a few times per month is common. Weekly sex while single is the exception, not the norm.
Sexual satisfaction doesn’t track neatly with frequency, either. Research on single adults finds that satisfaction depends more on the quality of encounters, feelings of autonomy, and whether someone’s sexual life aligns with their own preferences rather than hitting any particular number. A single person having sex a few times per year by choice may be perfectly content, while someone having sex monthly but wanting more may feel frustrated. The numbers provide a benchmark, but they’re a poor measure of whether any individual’s experience is “right.”
