Difficulty reaching orgasm or ejaculating is more common than most men realize, affecting up to 5% of men at some point in their lives. The causes range from medications and alcohol to masturbation habits, stress, and underlying health conditions. In most cases, something identifiable is driving the problem, and it can be addressed.
Medications Are the Most Common Culprit
If you recently started a new medication and noticed the change, that’s likely your answer. Antidepressants known as SSRIs are notorious for delaying or completely blocking orgasm. These include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), escitalopram (Lexapro), and citalopram (Celexa). SSRIs work by increasing serotonin activity in the brain, which helps with depression and anxiety but also suppresses the signals your nervous system needs to reach climax. Some people on these medications find orgasm takes much longer than usual; others can’t get there at all.
Blood pressure medications, opioid painkillers, and certain anti-seizure drugs can cause the same problem. If you suspect a medication is involved, don’t stop taking it on your own. Alternatives exist that are less likely to interfere. Bupropion (Wellbutrin), for instance, works through different brain chemistry and sometimes actually improves sexual response. Your prescriber can often switch you to something that treats your condition without this side effect.
Masturbation Habits and Reduced Sensitivity
A pattern sometimes called “death grip” is one of the more common and least discussed causes. It refers to desensitization of the nerves in the penis from frequently masturbating with a very tight grip, high speed, or one very specific technique. Over time, the nerve endings require more and more pressure to register sensation, creating a cycle where partnered sex simply can’t replicate the intensity your body has adapted to. The result: you can finish on your own but not with a partner.
The fix is straightforward but requires patience. Reducing masturbation frequency, loosening your grip, varying your technique, and using lubrication all help your nerve sensitivity gradually reset. Some men take a break from masturbation entirely for a few weeks to speed up the process. This isn’t a permanent condition. It’s a learned pattern, and it can be unlearned.
Frequent pornography use can compound the issue by training your arousal response to very specific visual stimuli that don’t match real-world sex. If you find that you’re aroused by porn but struggle to stay aroused with a partner, that disconnect is worth examining.
Alcohol and Recreational Drugs
Alcohol slows your central nervous system and alters neurotransmitter activity in the brain, particularly the chemicals that regulate nerve signaling. After a few drinks, ejaculation can take 30 minutes or longer, and with heavier drinking, orgasm may not happen at all. This is one of the most straightforward causes: if it only happens when you’ve been drinking, alcohol is your answer.
Recreational drugs including cocaine, MDMA, and amphetamines can also interfere, both acutely and with chronic use. Cannabis affects people differently, but some men report difficulty finishing while high. If substances are involved, the simplest test is to see whether the problem disappears when you’re sober.
Stress, Anxiety, and Being in Your Own Head
Your brain is the primary organ involved in orgasm, and psychological state matters enormously. Performance anxiety is especially common: the more you worry about whether you’ll be able to finish, the harder it becomes. That worry activates your sympathetic nervous system (the fight-or-flight response), which directly opposes the relaxation your body needs to reach climax. It becomes a self-reinforcing loop.
Relationship tension, stress at work, depression, and past trauma can all play a role. Some men experience this situationally, only with a particular partner or in certain contexts, which is a strong signal that the cause is psychological rather than physical. Sex therapy and cognitive behavioral therapy both have solid track records for breaking the anxiety cycle. Sometimes simply understanding that the problem is anxiety-driven, not a sign that something is physically wrong, is enough to start resolving it.
Hormonal Imbalances
Low testosterone reduces sex drive and can make orgasm harder to reach. But another hormone most men have never heard of, prolactin, can be equally important. Prolactin levels above roughly 35 ng/mL are linked to low libido and delayed ejaculation. Elevated prolactin can result from certain medications (including some antipsychotics), a small benign growth on the pituitary gland, or other medical conditions. A simple blood test can check both testosterone and prolactin levels, and treatment for either imbalance is well-established.
Nerve Damage and Chronic Conditions
Diabetes is one of the more common medical causes. Chronically high blood sugar damages both nerves and blood vessels over time, and the nerves involved in ejaculation are vulnerable to this. Men with poorly controlled diabetes often develop sexual difficulties gradually, sometimes before they even know they have diabetes.
Multiple sclerosis, spinal cord injuries, and surgeries involving the prostate or lower spine can all disrupt the nerve pathways that carry signals between the genitals and the brain. These causes tend to be more obvious because they come alongside other neurological symptoms or follow a known medical event. Cardiovascular disease, which reduces blood flow throughout the body, can also contribute. Smoking worsens vascular function by narrowing blood vessels and lowering nitric oxide, a chemical your body uses to direct blood flow to the penis.
Aging and Changing Sensitivity
As men get older, it naturally takes longer to reach orgasm. Nerve sensitivity decreases gradually, testosterone levels decline (typically about 1% per year after age 30), and blood flow becomes less robust. This doesn’t mean the problem is inevitable or untreatable. It does mean that what worked at 25 may not work at 45, and adjusting expectations, techniques, and the amount of direct stimulation involved in sex is a normal part of adapting.
What You Can Do About It
Start by identifying whether the problem is situational or consistent. If you can orgasm from masturbation but not with a partner, the cause is almost certainly related to technique, psychology, or the dynamic between you. If you can’t orgasm at all under any circumstances, a medical cause is more likely.
Practical steps that help many men include reducing or eliminating alcohol before sex, changing masturbation habits (lighter grip, less frequency, more variety), exercising regularly to improve blood flow and reduce stress, and communicating openly with your partner about what feels good. Exercise alone makes a meaningful difference for many men by boosting circulation and lowering anxiety.
If the problem persists, a doctor can check for hormonal imbalances, medication side effects, and nerve or vascular issues. There are no medications specifically approved for delayed ejaculation, but several drugs used for other conditions, including buspirone (an anxiety medication) and amantadine (a Parkinson’s medication), are sometimes prescribed off-label and can help. The right path depends entirely on the underlying cause, which is why figuring out your specific trigger matters more than trying random solutions.
