Taking a long time to ejaculate is more common than most people realize, and the causes range from everyday habits to medications to hormonal shifts. The median time to ejaculation during intercourse is about 5.4 minutes, but normal ranges vary widely, from under a minute to over 40 minutes. When it consistently takes longer than 20 to 25 minutes of stimulation, or when you can’t finish at all despite wanting to, clinicians consider that delayed ejaculation. Here’s what’s actually going on and what drives it.
How Your Body Controls Ejaculation
Ejaculation is a reflex that depends on a chain of signals between your brain, spinal cord, and pelvic nerves. Your brain has to be aroused enough to send the right signals, your nervous system has to relay them without interference, and the muscles and nerves in your pelvis have to coordinate a response. A disruption at any point in that chain slows things down or stops the process entirely. The causes fall into a few major categories: medications, masturbation habits, psychological factors, hormones, nerve damage, and alcohol or other substances.
Medications Are the Most Common Culprit
If you started taking an antidepressant and noticed it suddenly takes much longer to finish, you’re far from alone. SSRIs and similar antidepressants are the single most common medical cause of delayed ejaculation. These drugs increase a brain chemical called serotonin, which is great for mood but directly slows the ejaculatory reflex.
The rates are significant. In one study of psychiatric outpatients, paroxetine caused delayed ejaculation in about 34% of users. Fluoxetine and venlafaxine each caused it in roughly 22%. Even mirtazapine, which is sometimes considered less problematic for sexual function, caused it in about 31% of users. If a medication lines up with when your symptoms started, that’s a strong clue. Other drug classes that can contribute include opioid painkillers, blood pressure medications, and anti-seizure drugs.
How Masturbation Habits Retrain Your Body
This is one of the most overlooked causes, especially in younger men. If you masturbate using a technique that your partner’s body simply can’t replicate, you may have trained your nervous system to respond only to very specific stimulation. Researchers call this an “idiosyncratic masturbatory style,” but it’s more commonly known online as “death grip.”
The pattern involves one or more of the following: unusually tight grip pressure, very fast speed, a specific body position, prolonged duration, or focused stimulation on one particular spot. Some men develop these habits over years without realizing it, and they work fine for solo sex. But during partnered sex, the sensations are different, softer, and less targeted, so the body doesn’t reach the threshold needed to trigger the reflex. Frequency matters too. Masturbating more than three times a week has been specifically linked to delayed ejaculation during partnered sex.
There’s also a fantasy component. If the mental imagery you rely on during masturbation is very different from what’s happening during sex with a partner, that gap between expectation and reality can stall arousal at a level that’s not quite enough to finish. The fix in these cases is behavioral: gradually retraining your body to respond to less specific, less intense stimulation.
Anxiety and “Spectatoring”
Your mental state during sex has a direct, physical effect on ejaculation. When you’re anxious, stressed, or self-conscious, your body shifts into a fight-or-flight mode that actively works against the relaxed arousal state needed to ejaculate. Performance anxiety is especially disruptive because it creates a feedback loop: you notice it’s taking a while, you start worrying about it, that worry pulls you further from orgasm, and the cycle reinforces itself.
A related phenomenon is “spectatoring,” where instead of being mentally present during sex, you’re watching yourself from the outside, monitoring your performance, checking whether you’re close. This splits your attention and reduces the mental arousal that’s a critical part of the ejaculatory reflex. Relationship tension, unresolved conflict, or simply not feeling emotionally connected to a partner can have the same dampening effect. The body needs a combination of adequate physical friction and sufficient mental engagement. Researchers describe this as the “friction and fantasy” model: if either one is lacking, the process stalls.
Hormones That Affect the Reflex
Two hormones play an outsized role. Low testosterone reduces blood flow to the penis and makes the nerves there less sensitive, which means it takes more stimulation and more time to reach the point of ejaculation. Testosterone levels naturally decline with age, which is one reason delayed ejaculation becomes more common in men over 40.
The other hormone to know about is prolactin. When prolactin levels are abnormally high, it can directly block ejaculation. This sometimes happens because of a small, non-cancerous tumor on the pituitary gland that overproduces the hormone. The good news is that both of these hormonal causes are treatable. Testosterone therapy restores nerve sensitivity and blood flow, while medication or, less commonly, surgery to lower prolactin levels can resolve the issue.
Nerve Damage and Chronic Conditions
Because ejaculation depends on a nerve pathway running from the brain through the spinal cord to the pelvis, anything that damages those nerves can slow or prevent the reflex. Diabetes is one of the most common causes. Over time, high blood sugar damages small nerve fibers throughout the body, including the ones in the pelvic region that control ejaculation. This is called diabetic neuropathy, and it affects sexual function in a large percentage of men with long-standing diabetes.
Multiple sclerosis, spinal cord injuries, and stroke can all disrupt the same pathway at different points. Pelvic surgeries, particularly prostate or colorectal surgery, can physically damage the nerves responsible. In these cases, delayed ejaculation is often one symptom among others, like reduced sensation or difficulty with erections.
Alcohol and Other Substances
Alcohol is a central nervous system depressant, and even moderate amounts slow the brain’s processing speed. It alters the activity of key brain chemicals involved in sexual arousal and interferes with the nerve signals needed to maintain arousal and reach orgasm. Chronic heavy drinking compounds the problem over time, but even a few drinks on a given night can noticeably extend the time it takes to ejaculate, or make it impossible altogether. Recreational drugs, particularly opioids, stimulants, and cannabis in some users, can have similar effects.
When It Becomes a Clinical Diagnosis
Not every instance of taking a long time to finish is a medical problem. The clinical threshold for delayed ejaculation requires that the issue is present during at least 75% of sexual encounters, has persisted for six months or more, and causes you genuine distress. An expert panel also set a practical benchmark: consistently needing more than 20 to 25 minutes of active stimulation to ejaculate, combined with personal frustration about it.
Clinicians distinguish between lifelong delayed ejaculation, which has been present since a person’s first sexual experiences, and acquired delayed ejaculation, which develops after a period of normal function. The acquired type is far more common and usually easier to pin to a specific trigger like a new medication, a health change, or a shift in relationship dynamics. If the issue is situational, meaning it happens with a partner but not during masturbation, that points strongly toward psychological or behavioral causes rather than a physical one.
What Actually Helps
The most effective approach depends entirely on the cause. For medication-related delayed ejaculation, the options include switching to a different drug, adjusting the dose, or timing the dose differently relative to sexual activity. These decisions involve weighing the benefit of the medication against the sexual side effect.
For masturbation-related causes, the standard approach is a structured retraining process: reducing frequency, loosening grip, using less speed, and gradually shifting the stimulation pattern to more closely match what partnered sex feels like. Many men see improvement within a few weeks of consistent changes.
For psychological causes, therapy focused on reducing performance anxiety, addressing spectatoring, and improving communication with a partner can be highly effective. Couples-based approaches tend to work better than individual therapy for this issue because the dynamic between partners often plays a role in maintaining the cycle. Hormonal causes are addressed with hormone therapy, and nerve-related causes are managed by treating the underlying condition when possible or adapting sexual techniques to work with reduced sensation.
