Difficulty reaching orgasm or ejaculating is more common than most men realize, and it almost always has an identifiable cause. The medical term is delayed ejaculation, and it ranges from occasionally taking longer than expected to being completely unable to finish during partnered sex. It becomes a clinical concern when it happens during 75% or more of sexual encounters over at least six months, but even occasional difficulty can be frustrating. The causes fall into a few broad categories: medications, masturbation habits, psychological factors, alcohol, and less commonly, nerve or hormonal issues.
Medications Are the Most Common Cause
Antidepressants, especially SSRIs, are the single most frequent reason men struggle to ejaculate. These medications work by increasing serotonin levels in the brain, which is great for mood but directly slows down the orgasm reflex. This isn’t a rare side effect. It’s so predictable that some of these same drugs are prescribed off-label specifically to treat premature ejaculation. If you started having trouble around the same time you began a new medication, that connection is worth exploring with whoever prescribed it.
Other medications that can cause the same problem include certain blood pressure drugs, antipsychotics, and opioid painkillers. Even over-the-counter antihistamines can occasionally interfere. The effect is usually reversible once the medication is changed or the dose is adjusted, though that decision should involve your prescriber since stopping abruptly can cause its own problems.
Masturbation Habits and Sensitivity
This one gets discussed a lot online, and there’s real substance behind it. When someone habitually masturbates with a very tight grip, high speed, or a very specific motion, the nerves in the penis gradually become desensitized to anything less intense. The result is a cycle: declining sensitivity leads to gripping harder, which causes further desensitization. Over time, the sensations of vaginal or oral sex simply can’t match what the hand provides, making it difficult or impossible to finish with a partner.
The fix is straightforward but requires patience. Reducing masturbation frequency, loosening your grip, varying technique, and using lubrication can help retrain sensitivity over a period of weeks. Some men find it helpful to stop masturbating entirely for a stretch to allow nerve sensitivity to reset. This isn’t a permanent condition, but it won’t resolve on its own if the same habits continue.
Stress, Anxiety, and Getting in Your Head
Your nervous system has two competing modes. The parasympathetic system handles arousal and relaxation. The sympathetic system handles the “fight or flight” response. Sexual function requires the parasympathetic system to be running the show for most of the encounter, and the sympathetic system plays a role only at the very end, during the orgasm reflex itself. When you’re anxious, stressed, or mentally distracted, the sympathetic system activates too early and too broadly, suppressing the bodily functions you actually need.
Performance anxiety creates a particularly vicious loop. You worry about not being able to finish, which triggers the stress response, which makes it harder to finish, which increases the worry. This pattern can start after a single bad experience and reinforce itself over time. Relationship tension, body image concerns, work stress, or even just being overly focused on your partner’s experience can all pull you out of the mental space needed to reach orgasm.
The practical difference between psychological and physical causes often shows up in one key pattern: if you can ejaculate fine on your own but not with a partner, the cause is more likely psychological or related to the difference in stimulation. If you struggle in both situations, medications, habits, or a physical issue are more likely.
Alcohol and Other Depressants
Alcohol slows down your central nervous system and alters the neurotransmitters that carry signals between your brain and your body, including your penis. A drink or two might lower inhibitions, but beyond that, alcohol directly delays ejaculation and makes orgasm harder to reach. This is a dose-dependent effect: the more you drink, the more pronounced the problem. For some men, even moderate drinking is enough to make the difference.
Cannabis, benzodiazepines, and recreational drugs can produce similar effects through different mechanisms, all ultimately dulling the nerve signaling required to reach the orgasm threshold. If the difficulty only happens when you’ve been drinking or using substances, the connection is probably exactly what it seems.
Hormones and Physical Causes
Low testosterone is often the first thing men suspect, but research suggests the connection isn’t as direct as you’d think. A study examining the relationship between testosterone levels and ejaculation timing found no significant association between the two, meaning routine hormone testing isn’t particularly useful for diagnosing this specific problem. Testosterone affects sex drive more than it affects the ability to ejaculate once you’re already aroused.
Prolactin, a different hormone, may play a more direct role. One study of 72 men unable to reach orgasm found that 69% improved after treatment to lower their prolactin levels, with about half of those men returning to completely normal function. Elevated prolactin is uncommon, but it’s worth checking if other causes have been ruled out.
Nerve damage from diabetes, spinal cord injuries, or pelvic surgery (especially prostate surgery) can physically disrupt the ejaculatory reflex. Aging also gradually reduces nerve sensitivity, which is why some men notice the problem developing in their 40s or 50s without any other obvious explanation.
Lifelong Versus New-Onset Difficulty
This distinction matters because it points toward different causes. Lifelong delayed ejaculation, meaning you’ve always had difficulty finishing, tends to have deeper roots. It may involve how your nervous system is wired, long-standing psychological patterns around sex, or masturbation habits that developed early. It affects a smaller number of men and often benefits from working with a sex therapist alongside any physical evaluation.
Acquired delayed ejaculation, where things used to work fine and then changed, is more common and usually easier to trace. The most productive question to ask yourself is: what else changed around the same time? A new medication, increased stress, heavier drinking, a shift in the relationship, or a new health diagnosis will often line up with when the problem started.
What Actually Helps
The single most effective step is identifying the cause, because the solutions are different for each one. If a medication is responsible, switching to an alternative or adjusting the dose resolves it for most men. If masturbation habits are the issue, retraining sensitivity takes a few weeks of deliberate changes. If anxiety is the driver, cognitive behavioral therapy or working with a sex therapist has strong evidence behind it, and the improvement tends to be lasting rather than temporary.
For men whose difficulty is caused by antidepressant side effects specifically, certain medications can counteract the problem. In one case series, about 48% of patients with antidepressant-related orgasm difficulty improved with a medication that blocks the excess serotonin activity responsible for the delay. These are prescription options a urologist or psychiatrist can discuss.
Couples-focused strategies also help, particularly when the issue creates tension in a relationship. Shifting the focus away from orgasm as the goal of every sexual encounter, incorporating different types of stimulation, and open communication about what feels good all reduce the pressure that makes the problem worse. Many men find that the less they fixate on the outcome, the easier it becomes to get there.
