Taking a long time to ejaculate is more common than most people realize, and it almost always has an identifiable cause. Clinicians generally consider anything beyond 25 to 30 minutes of stimulation to be delayed ejaculation. The causes range from medications and masturbation habits to hormonal shifts and psychological factors, and most of them are treatable once you know what’s going on.
How Common Delayed Ejaculation Is
Delayed ejaculation is the least studied of the major male sexual difficulties, but it’s far from rare. For a formal diagnosis, the delay needs to happen during 75% or more of sexual encounters and persist for at least six months. It also has to be something you don’t want, not a deliberate technique. Many men experience occasional episodes without meeting that clinical threshold, especially during stress, fatigue, or after drinking alcohol.
The condition splits into two categories. Lifelong delayed ejaculation means it has always been this way for you. Acquired delayed ejaculation means things changed at some point, which often makes the cause easier to pinpoint because you can look at what else changed around the same time.
Medications Are the Most Common Culprit
If you started taking an antidepressant and then noticed the change, that’s likely your answer. SSRIs (selective serotonin reuptake inhibitors) are well known to delay orgasm and ejaculation. Fluoxetine, paroxetine, sertraline, citalopram, and fluvoxamine all carry this side effect. In clinical studies, both citalopram and fluoxetine measurably increased the time to ejaculation in otherwise healthy men. The effect is so reliable that some of these drugs are prescribed off-label specifically to treat premature ejaculation.
Other medications that can slow things down include certain blood pressure drugs, anti-seizure medications, opioid painkillers, and some antipsychotics. If you suspect a medication is responsible, the timing of when the problem started relative to when you began the drug is the biggest clue.
How Masturbation Habits Play a Role
This is one of the most underrecognized causes. If you’ve trained yourself to climax using a very specific technique, speed, or grip pressure that partnered sex can’t replicate, your body may simply not receive enough of the right stimulation during intercourse. The Sexual Medicine Society of North America describes these as “idiosyncratic” masturbation practices. A man accustomed to a very fast motion, tight grip, or particular type of pressure may find the slower, softer sensations of intercourse insufficient to reach the finish line.
This is sometimes called “death grip syndrome” informally, though that’s not an official medical term. The good news is that it’s one of the most fixable causes. Gradually changing your masturbation technique to use lighter pressure, slower speed, and varied stimulation can retrain your body’s response over several weeks.
Hormonal Imbalances
Low testosterone is often the first hormonal suspect, though the connection to ejaculation timing specifically is complicated. Testosterone drives libido and arousal more directly than it controls ejaculation speed, and clinical trials of testosterone supplementation for delayed ejaculation have shown limited benefit on their own.
Elevated prolactin is a more targeted hormonal cause. High prolactin levels suppress the hormones that drive sexual function, and this can happen even when testosterone levels test in the normal range. In one study, treating elevated prolactin improved sexual function in about 64% of men, including improvements in orgasm, desire, and satisfaction. Prolactin isn’t part of a standard blood panel, so it’s worth asking about specifically if other causes have been ruled out.
Nerve Damage and Medical Conditions
Ejaculation depends on a precise chain of nerve signals running from the brain through the spinal cord to the pelvic region. Anything that disrupts those signals can slow or prevent climax. Diabetes is one of the most common medical causes because long-term high blood sugar damages small nerve fibers throughout the body, including those involved in sexual response. Multiple sclerosis, spinal cord injuries, and stroke can all affect the same pathways.
Prostate surgery and other pelvic procedures can also damage the nerves responsible for ejaculation. If your difficulty started after a surgery in that area, nerve damage is the most likely explanation.
Psychological and Relationship Factors
Your brain is the primary organ involved in orgasm, which means psychological factors can be just as powerful as physical ones. Performance anxiety creates a feedback loop: you worry about taking too long, the worry pulls your attention away from physical sensation, and that makes it take even longer. Relationship tension, unresolved conflict, or feeling emotionally disconnected from a partner can have the same effect.
Religious or cultural guilt around sex, a history of sexual trauma, and depression itself (separate from antidepressant side effects) can all contribute. One pattern clinicians look for is whether the delay happens only during partnered sex or also during masturbation. If you can climax in a normal timeframe alone but not with a partner, psychological factors are more likely at play.
What Actually Helps
Treatment depends entirely on the cause, which is why identifying it matters so much. For medication-related delays, switching to a different drug or adjusting the dose often resolves the issue. For antidepressant-induced cases specifically, several approaches have shown benefit. In one study, about 81% of men with antidepressant-related sexual problems responded to a supplement that works by blocking certain serotonin receptors. Another medication improved sexual function in roughly 48% of similar cases. Bupropion, a different type of antidepressant that works through dopamine rather than serotonin, improved orgasm delay in 70% of non-depressed men in one trial, though results were more modest in men with lifelong delayed ejaculation.
For psychological causes, sex therapy uses a technique called sensate focus, developed by researchers William Masters and Virginia Johnson. It works by removing the pressure to perform. You and your partner go through structured exercises that start with non-sexual touch, focusing purely on sensation rather than any goal. Over time, the exercises gradually incorporate sexual touch while keeping the emphasis on pleasure and connection instead of climax. The gradual approach lets you work through anxiety and mental blocks at your own pace.
For habit-related causes, the approach is retraining. This means deliberately varying your masturbation technique over weeks, using less pressure, different speeds, and ideally conditions that more closely resemble partnered sex. Some therapists recommend reducing masturbation frequency as well, to increase sensitivity.
Sorting Out Your Specific Cause
A few questions can help you narrow things down before you ever see a clinician. First, has this always been the case, or did it develop at a specific point? If it developed, what else changed: new medication, new relationship, surgery, a stressful period? Second, does the delay happen during masturbation too, or only during partnered sex? If only with a partner, psychological and relationship factors move to the top of the list. If it happens regardless, medications, hormones, nerve issues, or masturbation habits are more likely.
Third, consider your overall health. Uncontrolled diabetes, neurological symptoms, or fatigue and low mood could point toward a physical or hormonal cause that deserves blood work and a proper evaluation. Delayed ejaculation often responds well to treatment once the right cause is identified, and in many cases, the fix is simpler than you’d expect.
