Difficulty ejaculating, or not being able to ejaculate at all, is more common than most people realize. It can happen during sex with a partner, during masturbation, or both. The causes range from medications and nerve-related conditions to psychological factors like anxiety or habitual masturbation patterns. Clinically, when ejaculation takes longer than 20 to 25 minutes of stimulation or doesn’t happen at all on most sexual occasions, it’s considered delayed ejaculation.
Medications Are the Most Common Culprit
If you recently started a new medication and noticed a change, that’s the first place to look. Antidepressants, particularly SSRIs like sertraline, paroxetine, fluoxetine, and citalopram, are well-known for disrupting ejaculation. Between 58% and 73% of people taking SSRIs experience some form of sexual dysfunction, and delayed or absent ejaculation is one of the most frequent complaints. In one study, 61% of men taking sertraline reported difficulty reaching orgasm during a 16-week trial. Paroxetine tends to be the worst offender, with rates around 70%.
Other antidepressants carry lower risk. Bupropion, for instance, caused sexual side effects in only 14% of users compared to 73% for SSRIs in one head-to-head comparison. Mirtazapine falls somewhere in the middle. Beyond antidepressants, certain blood pressure medications and drugs used for prostate enlargement (alpha-blockers) can also interfere with ejaculation. If you suspect a medication is the cause, it’s worth discussing alternatives with your prescriber rather than stopping on your own.
How Masturbation Habits Play a Role
One of the most overlooked causes is a mismatch between how you masturbate and what partnered sex feels like. If you’ve trained your body to respond to very specific, high-friction, or high-pressure stimulation, the comparatively gentler sensations of oral or vaginal sex may not be enough to push you over the edge. This is sometimes called “idiosyncratic masturbatory style,” and it’s surprisingly common.
The fix involves gradually retraining your body’s response. Sex therapists typically recommend reducing how often you masturbate to orgasm, particularly within 72 hours of planned partnered sex. Switching your grip, using your non-dominant hand, or using less pressure helps your body adapt to a wider range of stimulation. The goal is to close the gap between what you experience alone and what you experience with a partner. Condom use during solo sessions can also help reduce reliance on direct friction.
Psychological Factors
Your mental state during sex matters enormously. Performance anxiety is one of the biggest psychological barriers to ejaculation. The more you focus on whether you’ll be able to finish, the harder it becomes. This creates a feedback loop: one difficult experience leads to worry, which makes the next experience harder, which builds more worry.
Other psychological contributors include depression, poor body image, relationship tension, unresolved cultural or religious guilt around sex, and a disconnect between your fantasies and the reality of partnered sex. If your internal experience during sex with a partner feels fundamentally different from what arouses you privately, that gap can prevent your body from reaching the threshold it needs.
Nerve Damage and Neurological Conditions
Ejaculation depends on a complex chain of nerve signals running from the brain through the spinal cord to the pelvic region. Anything that disrupts this pathway can delay or prevent ejaculation entirely. Diabetes is one of the most common medical causes, because long-term high blood sugar damages the small nerves that control the ejaculatory reflex. Multiple sclerosis, Parkinson’s disease, and spinal cord injuries all affect the same pathways. In people with neurological disorders, sexual dysfunction rates run as high as 80%.
Spinal cord injuries have specific patterns depending on location. Higher injuries tend to preserve reflex-based sexual responses but eliminate those driven by arousal and mental stimulation. Lower injuries, particularly to the base of the spine, reduce genital sensation and make orgasm much harder to reach. Prostate surgery and other pelvic procedures can also damage the nerves involved.
Retrograde Ejaculation: When It Goes Backward
If you feel the sensation of orgasm but little or no fluid comes out, the issue may not be delayed ejaculation at all. In retrograde ejaculation, the muscle at the opening of the bladder doesn’t close properly during orgasm. Instead of traveling out through the penis, semen redirects into the bladder. It’s harmless, and you’ll typically notice cloudy urine afterward.
Common causes include prostate or bladder surgery, diabetes-related nerve damage, and certain medications like alpha-blockers prescribed for enlarged prostate or high blood pressure. Retrograde ejaculation doesn’t affect your health, but it can be a concern if you’re trying to conceive.
What About Testosterone?
Many men assume that difficulty ejaculating points to low testosterone, but research doesn’t support this. A study specifically examining the relationship between ejaculation time and testosterone levels found no association. Men with delayed ejaculation did take significantly longer to reach orgasm than other men, but their testosterone levels were no different. Routine hormone testing isn’t typically useful for this issue unless other symptoms of low testosterone are present, like low sex drive, fatigue, or loss of muscle mass.
Treatment Options That Work
Treatment depends on the cause. If a medication is responsible, switching to one with a lower sexual side-effect profile often resolves the problem. Bupropion is frequently used as an alternative antidepressant for this reason, or it can be added alongside an SSRI to counteract the sexual effects.
For psychological and behavioral causes, sex therapy built around gradual retraining is the standard approach. The process typically starts with removing the pressure to ejaculate during partnered sex entirely. You progress through stages of stimulation, from manual to oral to intercourse, rebuilding your body’s ability to respond at each level. Fantasizing during partnered sex or incorporating erotica is encouraged when intrusive or anxious thoughts are blocking arousal. The key principle is reducing the “performance demand” that makes the problem worse.
No medication is specifically approved for delayed ejaculation, but several are used off-label with varying success. One that has shown promise is cabergoline, which lowers prolactin levels. In a study of 72 men who couldn’t reach orgasm, 69% improved with cabergoline treatment, and about half of those returned to normal function. For antidepressant-related cases specifically, cyproheptadine taken one to two hours before sex has helped some men, at doses ranging from 2 to 16 mg. These are conversations to have with a doctor who can weigh the tradeoffs for your specific situation.
Lifelong vs. Acquired: Why the Distinction Matters
If you’ve never been able to ejaculate easily, even from your earliest sexual experiences, the cause is more likely to be neurological, anatomical, or rooted in deeply ingrained patterns. If the problem developed after a period of normal function, the trigger list is more focused: a new medication, a health change, a shift in your relationship, increased stress, or aging-related changes in sensitivity. Acquired cases generally respond better to treatment because there’s a clear baseline to return to. Either way, the condition is treatable for most men once the underlying cause is identified.
