It’s a distressing experience: a man begins sex with a firm erection, only for to lose it minutes later. In other cases, he may not get fully erect at all. For partners on the receiving end of this, it can feel personal—leading to questions like, “Is it me?” But in most cases, the problem lies elsewhere, and it’s far more common than many realize.
Erectile Issues Are Common — And Often Misunderstood
Temporary or occasional erectile dysfunction (ED) is extremely common. According to the Massachusetts Male Aging Study, approximately 52% of men experience some form of erectile difficulty during their lifetime, and prevalence increases with age. But even younger men aren’t immune—studies have shown that 1 in 4 men seeking help for ED are under 40, with the majority experiencing it in a situational or inconsistent way.
Common Causes of Man Losing an Erection During Sex
1. Performance Anxiety or Psychological Stress
Performance pressure is a major culprit. Worrying about how long he’ll last, whether he’ll satisfy his partner, or past failures can create a vicious cycle of anxiety and sexual dysfunction. Stress increases cortisol levels, which interferes with testosterone and nitric oxide pathways—both vital for sustaining an erection.
Science says: An excerpt from the chapter Psychological Aspects of Erectile Dysfunction in the Contemporary Treatment of Erectile Dysfunction found that men with performance anxiety were significantly more likely to report erectile difficulties, even when physically healthy.
2. Reduced Blood Flow or Circulatory Issues
An erection is a blood flow event. If the vascular system is impaired, the penis may become erect but fail to stay that way. Conditions like high blood pressure, atherosclerosis, and even smoking can contribute to compromised blood vessels.
Scientific link: Research in Circulation (2005) established that ED is often an early warning sign of cardiovascular disease.
3. Low Testosterone Levels
Low testosterone doesn’t always lead to erectile dysfunction, but it can reduce libido, arousal, and stamina. This makes it harder for men to stay mentally and physically “in the moment,” resulting in a fading erection.
4. Alcohol or Medications
Even moderate alcohol consumption can blunt the nervous system and interfere with erectile function. Similarly, common medications—like antidepressants (SSRIs), antihypertensives, or certain antihistamines—can interfere with sexual performance.
What It Doesn’t Mean
Importantly, a man losing his erection is not automatically a sign that he’s lost interest in his partner, or that she’s unattractive. In most cases, the cause is physiological, psychological, or both.
In fact, the worry or guilt from disappointing a partner can compound the issue, making future attempts even more difficult.
When to Seek Help
If the issue is occasional, it’s usually nothing to worry about. But if it persists over weeks or months, it’s a good idea to consult a doctor. Erectile dysfunction can be a symptom of underlying health conditions—and in many cases, treatment is simple and effective.
Final Thoughts
Losing an erection during sex happens — frequently, and to millions of men. The causes can range from stress and anxiety to blood flow issues and hormonal imbalances. Rather than blame, judgment, or shame, what most men need is support, open communication, and in some cases, professional help.
