It’s a common belief that younger individuals tend to have a more fulfilling sexual experience.
However, a recent study conducted by the University of Tartu in Estonia suggests otherwise, identifying when sexual desire tends to peak.
The study examined data from over 67,000 adults aged between 20 and 84, aiming to discover which age group exhibits the highest sexual desire. Surprisingly, especially for men, the study contradicts the traditional belief that testosterone levels decline in men after their early thirties, leading to reduced sexual interest.
Contrary to these assumptions, the study revealed that male sexual desire actually peaks around the age of 40.

Moreover, the findings indicate that men in their 60s maintain a level of sexual interest comparable to men in their 20s. From early adulthood, men’s sexual appetites gradually increase, hitting their peak in the early 40s before experiencing a decline.
In contrast, women’s sexual desire peaks during early adulthood, specifically from the 20s to early 30s, and then diminishes with age, significantly dropping after reaching 50.
“The mid-life peak in men suggests that factors beyond biological ageing, such as relational dynamics, may play a more significant role than initially anticipated,” the researchers noted in the journal Scientific Reports.
“For example, men in their forties are more likely to be in stable long-term relationships, which have been associated with increased sexual activity and emotional intimacy.”
The study also highlighted: “A particularly notable finding is just how substantially higher men’s sexual desire was compared to women’s throughout most of the adult life span.”
Bisexual individuals reported the highest levels of sexual desire, as did those holding an undergraduate degree, while postgraduates reported the lowest.
Professions such as the military, machine operators, drivers, and senior managers recorded high levels of desire, whereas office workers and those in customer service had lower levels.

Interestingly, individuals in happy and satisfied relationships reported only a slight increase in desire. For women, having children often resulted in decreased desire, while fathers experienced an increase.
While data indicated general trends, there were significant variations in individual results, with some women displaying higher sexual desire than their male counterparts.
Separately, an expert has discussed why men may lose interest in sex within long-term relationships.
Dr. Snyder, in his book Love Worth Making: How To Have Ridiculously Great Sex In A Long-Lasting Relationship, suggested that reasons could range from psychological reminders such as a man being reminded of his mother to emotional withdrawal.
He emphasized the importance of mutual understanding and finding ways to please each other, pointing out that even small moments of erotic excitement can enhance a couple’s sex life. He also highlighted the importance of not adhering strictly to a ‘sex schedule’ and embracing spontaneity to improve one’s sex life.
