Taking a long time to reach orgasm is more common than most people realize, and it almost always has an identifiable cause. The median time to ejaculation during intercourse is about 5.4 minutes, based on a multinational study of over 500 couples, but the range spans from under a minute to over 44 minutes. When it consistently takes longer than 20 to 25 minutes of stimulation and it’s causing you frustration, clinicians consider that delayed ejaculation. The good news: most causes are treatable or reversible once you figure out what’s going on.
How Your Brain Controls the Finish Line
Ejaculation is ultimately a reflex controlled by your nervous system, and two brain chemicals play tug-of-war over when it happens. Dopamine acts as the accelerator. It drives arousal and pushes you toward climax. Serotonin acts as the brake, inhibiting the ejaculatory reflex. When your brain’s balance tips toward more serotonin activity or less dopamine activity, it takes longer to get there.
A third chemical, oxytocin (sometimes called the bonding hormone), also plays a role. It strengthens the muscular contractions involved in ejaculation and shortens the time it takes to climax. Anything that disrupts the normal interplay of these three signals, whether it’s a medication, a health condition, or a substance like alcohol, can push your timing further out.
Medications Are the Most Common Culprit
If you started taking an antidepressant and noticed the change, that’s very likely your answer. SSRIs (the most widely prescribed class of antidepressants) work by flooding the brain with serotonin, which is exactly the chemical that delays ejaculation. The effect is so reliable that SSRIs are actually prescribed off-label to treat premature ejaculation.
The numbers are striking. Somewhere between 25% and 73% of people on an SSRI experience sexual side effects, depending on the specific drug and study. In one trial, 67% of men taking sertraline reported ejaculatory difficulties. Paroxetine tends to be the worst offender, with sexual dysfunction rates around 65 to 71%. If your antidepressant is the cause, your doctor can sometimes switch you to a different medication with a lower sexual side-effect profile.
Masturbation Habits Matter More Than You Think
This one catches a lot of people off guard. If you’ve trained yourself to orgasm using a very tight grip, a specific speed, or one particular motion, your body can become conditioned to need that exact type of stimulation. This is sometimes called “death grip syndrome,” though it’s not a formal medical diagnosis. The nerves in the penis gradually desensitize to lighter touch, making partnered sex feel like not quite enough.
It becomes a cycle: as sensitivity drops, you grip harder or stroke faster to compensate, which desensitizes you further. Over time, the gap between what your hand provides and what a partner’s body provides keeps widening. The friction during oral sex or intercourse is progressively less intense than a tight fist, so those experiences may not be enough to push you over the edge.
The fix involves retraining your body. Therapists who work with this issue recommend changing your masturbation technique: switching hands, loosening your grip, slowing down, and gradually shaping the experience to feel more like partnered sex. Avoiding orgasm for at least 72 hours before a partnered encounter can also lower the threshold. The goal is to widen the range of stimulation that works for you, rather than relying on one narrow routine.
Hormones and Health Conditions
Your hormonal balance has a direct, measurable effect on ejaculatory timing. A study of over 2,600 men found that as testosterone levels dropped, ejaculatory delay increased. At the same time, higher levels of prolactin (a hormone that typically rises after orgasm to create that “done” feeling) and thyroid-stimulating hormone were both independently associated with longer times to climax.
Low testosterone, high prolactin, and underactive thyroid are all testable with a simple blood draw. If any of these are off, treating the underlying hormonal issue often improves things.
Several medical conditions can also interfere with the nerve signals that trigger ejaculation. Diabetes is one of the most common, because long-term high blood sugar damages the small nerves throughout the body, including those in the pelvis. Multiple sclerosis, spinal cord injuries, stroke, and prior prostate surgery can all disrupt the same pathways. Even a urinary tract infection can temporarily affect things.
Alcohol, Nicotine, and Other Substances
Alcohol is a central nervous system depressant, and it earns that label. It slows the brain’s processing speed, reduces sensitivity to touch, and directly alters the neurotransmitter activity that controls ejaculation. A couple of drinks might delay things slightly. Heavier drinking can make orgasm genuinely difficult or impossible.
This isn’t limited to one big night out. Regular heavy drinking keeps your nervous system in a chronically dampened state. If you’ve noticed the problem lines up with increased drinking, cutting back is worth trying before looking for other explanations.
Psychological Factors
Your mental state during sex matters enormously because orgasm requires a certain level of mental immersion in the experience. Performance anxiety, stress, relationship tension, or simply being distracted can all keep your brain from fully engaging in arousal. Some men develop a pattern where they worry about taking too long, which creates anxiety, which makes them take even longer.
Pornography use can also play a role, not because it’s inherently harmful, but because it can create a mismatch between the visual and psychological stimulation you’re accustomed to and what’s happening during real-world sex. If your arousal has become dependent on very specific visual scenarios, partnered sex may not generate the same mental intensity.
Sex therapists address this through structured exercises that gradually rebuild arousal patterns. The approach typically starts with removing the pressure to orgasm entirely, focusing instead on progressing from neutral to pleasurable sensations without any expectation of a finish. From there, you learn to identify what thoughts, movements, and types of stimulation help you stay mentally engaged, then progressively transition from masturbation to partnered stimulation.
How to Start Figuring Out Your Cause
The most useful first step is identifying when the problem started and what else changed around that time. A medication change, a new relationship, increased stress, a shift in drinking habits, or a new health diagnosis can all point directly to the cause. If it’s been a lifelong pattern rather than a recent change, masturbation habits and psychological conditioning are more likely factors.
If you suspect a medical or hormonal cause, a basic workup including testosterone, prolactin, and thyroid levels can rule in or rule out the most common endocrine problems. For men on antidepressants, a conversation with the prescribing doctor about alternatives or adjunct strategies is often the fastest path to improvement.
For habit-related causes, the retraining process takes time but works for most men. Loosening your grip, varying your technique, spacing out your solo sessions, and practicing with less intense stimulation all help recalibrate your body’s threshold. Many men see noticeable changes within a few weeks of consistent effort.
