Taking a long time to reach orgasm during sex is more common than most people think, and it usually comes down to a mix of brain chemistry, physical sensitivity, medications, or psychological factors. In a large multinational study, the median time to ejaculation during intercourse was 5.4 minutes, but the range stretched from under a minute to over 44 minutes. If you’re consistently on the longer end and it’s bothering you or your partner, there are real, identifiable reasons why.
What Counts as “Too Long”
There’s no hard cutoff that separates normal from abnormal. Some people naturally take 15 or 20 minutes and are perfectly happy with that. It becomes a clinical issue, called delayed ejaculation, when there’s a consistent, bothersome inability to finish or a noticeable increase in how long it takes, despite being aroused and wanting to. Clinically, this needs to happen during at least 75% of sexual encounters over six months or more before it’s formally diagnosed.
Delayed ejaculation affects roughly 1% to 4% of men, making it the least common male sexual complaint. But a broader international survey of men aged 40 to 80 found that about 13% reported difficulty reaching orgasm, suggesting plenty of people experience this without it rising to a clinical diagnosis. Age also plays a role: younger men (18 to 30) have a median time of about 6.5 minutes, while men over 51 average closer to 4.3 minutes. So while ejaculation generally gets faster with age, the ability to reach orgasm can paradoxically become harder for some.
Your Brain Chemistry Sets the Threshold
Ejaculation is ultimately controlled by your nervous system, and two brain chemicals play opposing roles. Dopamine pushes you toward orgasm. Serotonin holds you back. Your brain maintains a baseline level of serotonin in the spinal cord that actively inhibits ejaculation until physical stimulation is strong enough to override that brake. If your natural serotonin activity is on the higher side, your threshold for reaching orgasm is higher too, meaning it simply takes more stimulation and more time.
This isn’t something you can feel or measure at home, but it explains why some people have always taken longer to finish, even from their very first sexual experiences. It’s a neurological setting, not a failing.
Medications That Raise the Bar
If the delay started after you began taking a new medication, that’s likely your answer. Antidepressants that increase serotonin levels, particularly SSRIs, are well known for making orgasm harder to reach. This isn’t a rare side effect; it’s one of the most common complaints people have on these drugs. In controlled studies, both citalopram and fluoxetine significantly delayed ejaculation compared to placebo, with citalopram showing the strongest effect.
Other antidepressants can also cause this by raising prolactin, a hormone that dampens sexual response. Beyond antidepressants, certain blood pressure medications, antipsychotics, and opioids can all interfere with the pathway from arousal to orgasm. If you suspect a medication is the cause, it’s worth a conversation about alternatives or dosage adjustments, because this is one of the most straightforward causes to address.
How Masturbation Habits Retrain Your Body
This is one of the most common and least talked about causes. If you masturbate with a very firm grip, fast speed, or a specific technique (like rubbing against a mattress while lying face down), your nervous system can become conditioned to respond only to that exact type of stimulation. The result: partnered sex doesn’t provide enough intensity to get you over the edge.
The International Society for Sexual Medicine describes this as a desensitization of the penis from frequent, rigorous masturbation. Speed, pressure, and frequency all shape how your body responds to touch during sex. The good news is that this is reversible. Gradually shifting to a lighter grip, slower pace, or a different position during masturbation can recalibrate your sensitivity over weeks to months. Some people also benefit from reducing how often they masturbate so that partnered stimulation feels more intense by comparison.
Hormonal Imbalances
Low testosterone (hypogonadism), an underactive thyroid, and elevated prolactin levels can all contribute to delayed ejaculation. These conditions don’t just lower desire; they can directly interfere with the physical process of reaching orgasm. If you’re also experiencing fatigue, low libido, weight changes, or mood shifts alongside the delay, a hormonal cause is worth investigating with bloodwork.
Anxiety and the “Watching Yourself” Problem
Performance anxiety doesn’t just cause erection problems. It can also keep you from finishing. When you’re anxious during sex, your sympathetic nervous system, the fight-or-flight system, stays activated. Orgasm requires a specific sequence of nervous system reflexes, and anxiety disrupts that sequence by keeping your body in a vigilant, tense state rather than letting it relax into climax.
A particular pattern called “spectatoring” makes this worse. Instead of being mentally present during sex, you’re monitoring yourself from the outside: wondering how long it’s been, whether your partner is getting frustrated, whether something is wrong with you. That mental distance pulls you further from the physical sensations you need to build toward orgasm. Depression, relationship stress, and unresolved feelings about sex can all have similar effects. Often the delay has both a physical and psychological component feeding into each other.
Alcohol and Recreational Drugs
Alcohol is a central nervous system depressant, and even moderate amounts can dull the nerve signals involved in orgasm. Heavy drinking reliably delays ejaculation, and chronic alcohol use can cause longer-term changes. Recreational drugs, particularly opioids and stimulants, also interfere with the ejaculatory reflex. If the delay only happens when you’ve been drinking or using substances, that connection is probably not a coincidence.
What You Can Do About It
The approach depends on the cause, but several strategies have real evidence behind them.
If masturbation habits are involved, retraining your body’s response is the first step. Use a lighter touch, vary your technique, and consider using lubrication to more closely mimic the sensations of partnered sex. Give it at least a few weeks of consistent change before judging results.
If anxiety or relationship dynamics are part of the picture, working with a sex therapist or counselor can help. Treatment is often more effective when both partners are involved, because the frustration and pressure that build around delayed ejaculation can create a cycle that makes it worse. Open conversation with your partner about what’s happening takes the secrecy and shame out of it, which alone can reduce the mental interference.
For medication-related delays, switching to a different drug or adjusting the dose often resolves the issue. Some antidepressants are much less likely to cause sexual side effects than others.
When the cause is hormonal or neurological, treatment options exist but are all used off-label, meaning no drug is specifically approved for delayed ejaculation. In studies, a drug that lowers prolactin levels helped about 69% of men who couldn’t reach orgasm, with about half returning to normal function. Other medications that counteract serotonin’s inhibitory effects have shown improvement rates ranging from about 42% to 81% depending on the drug and the study. These numbers aren’t guarantees, but they do show that pharmacological help is available when behavioral changes aren’t enough.
For many people, the fix is simpler than expected: adjusting a medication, changing a masturbation habit, or addressing the anxiety loop that’s keeping the body from doing what it’s designed to do. The delay doesn’t mean something is fundamentally broken. It means one or more specific, identifiable factors are raising the threshold your body needs to cross.
