Men often worry about how they measure up, and misleading ideas from porn don’t help. Here is what research actually shows.
How long does sex usually last?
The best-known data comes from a study of 500 couples in five countries who used a stopwatch to time sex. The median time from penetration to ejaculation was about 5.4 minutes. The range was enormous, from under a minute to over 40 minutes, and average times differed between countries and age groups.
In surveys of sex therapists, penetrative sex lasting 3 to 7 minutes was described as “adequate” and 7 to 13 minutes as “desirable.” Anything much longer was not seen as better.
The takeaway: there is no “correct” time. What matters is whether you and your partner are satisfied.
How long does an erection last?
There is little good data on the length of erections during partnered sex, because it depends on arousal, stimulation and when ejaculation happens. After ejaculation, erections normally fade within minutes.
At night, healthy men typically have three to five erections during sleep, often lasting 20 to 40 minutes each, mostly during REM sleep. These nighttime and morning erections are a sign of healthy blood flow and nerves.

The refractory period
After ejaculation, men enter a refractory period during which another erection or orgasm is difficult. It varies from a few minutes in young men to many hours or even a day in older men. This is normal and gets longer with age.
When an erection lasts too long
An erection lasting more than four hours is called priapism and is a medical emergency. It can permanently damage the penis if not treated. It’s more likely with some medications, injectable ED treatments, sickle cell disease and certain drugs. Go to an emergency department.

What to drink (and avoid)
No drink will make you last longer or give you firmer erections, but a few choices make a difference:
- Alcohol: a small amount may reduce anxiety, but more than a drink or two weakens erections and delays or blocks orgasm
- Water: staying hydrated supports energy and normal semen volume
- Energy drinks and lots of caffeine: may increase anxiety and heart rate for some men
- Watermelon and beetroot juice: often promoted because they contain citrulline or nitrates, which support blood flow. They’re healthy choices, but there’s no good evidence they improve erections on their own
How long does the average man last in bed?
A large study of couples found a median of about 5.4 minutes from penetration to ejaculation, with a very wide range.
Is it normal to lose an erection during sex?
Occasionally, yes, especially with tiredness, stress or alcohol. If it happens regularly, talk to a doctor.
How many erections does a man have at night?
Healthy men typically have three to five erections during sleep, each lasting around 20 to 40 minutes.
When is a long erection dangerous?
An erection that lasts more than four hours, called priapism, is a medical emergency and needs immediate treatment.
