Here is a thorough answer based on medical textbook evidence and research:

Is 35-40 Minutes to Ejaculation Normal?

Yes, it is within the wide range of human variation - but it is on the longer end.

What the Research Says About Normal Ejaculation Time

The most widely referenced study on this topic measured Intravaginal Ejaculation Latency Time (IELT) - the time from vaginal penetration to ejaculation - across five countries (Waldinger et al., 2005, PMID: 16422843).
Key findings:
  • Median IELT: ~5.4 minutes
  • The range across the general population is very broad - from under 1 minute to over 30+ minutes
  • There is no strict "too long" cutoff in clinical guidelines
According to Campbell-Walsh-Wein Urology (one of the leading urology textbooks), sexual therapists consider:
IELT DurationRating
Less than 1-2 minutesToo short (premature ejaculation)
3-7 minutesAdequate
7-12 minutesDesirable
13-30+ minutesLonger than average, but not a disorder

Is 35-40 Minutes a Problem?

Taking 35-40 minutes to ejaculate is not a medical disorder on its own, but if it is causing distress or difficulty, it falls under a condition called delayed ejaculation (also called ejaculatory dysfunction or inhibited ejaculation).
Delayed ejaculation is considered clinically significant only when it:
  • Causes personal distress or dissatisfaction
  • Occurs consistently over time
  • Cannot be explained by medications or other medical conditions

Common Causes of Longer-Than-Average Ejaculation Time

  1. Psychological factors - anxiety, relationship issues, stress, performance pressure, or reduced arousal
  2. Medications - antidepressants (especially SSRIs), antipsychotics, antihypertensives, and alcohol are well-known causes
  3. Hormonal issues - low testosterone (hypogonadism)
  4. Nerve-related - diabetes-related neuropathy, spinal conditions
  5. Masturbation habits - very firm or specific stimulation during masturbation may make penetrative sex less stimulating
  6. Age - ejaculation typically takes longer as men age, and this is completely normal

When to See a Doctor

Consult a doctor if:
  • The long ejaculation time causes you or your partner distress
  • It has changed suddenly (was not always like this)
  • You cannot ejaculate at all during sex
  • You have other symptoms like reduced libido, fatigue, or erectile problems

Bottom line: 35-40 minutes is longer than the statistical average, but it is not automatically abnormal or harmful. If it doesn't cause distress to you or your partner, it requires no treatment. If it is bothersome, a urologist or sexual health specialist can help identify any underlying cause.

I think it is because of masterbation before 1 day of sex

Your thinking is very likely correct. Here is a clear explanation:

How Masturbation the Day Before Affects Ejaculation Time

The Science Behind It

When you ejaculate (through masturbation or sex), your body goes into a refractory period - a recovery phase. During this time:
  • Semen volume is lower - the seminal vesicles and prostate haven't fully refilled
  • Nerve sensitivity is reduced - the sensory threshold for triggering ejaculation is temporarily raised
  • Arousal levels reset - it takes more stimulation to reach the same peak of excitement
  • Testosterone and dopamine levels that drive sexual drive take time to fully restore
If you masturbate on Day 1 and have sex on Day 2, your body may still be in partial recovery, meaning it takes significantly longer to reach the ejaculatory reflex - hence the 35-40 minutes.

How Long Does Full Recovery Take?

Recovery time varies by individual and age:
FactorEffect on Recovery Time
Age (younger men)Faster recovery - hours to 1 day
Age (older men 40+)Slower recovery - 1-3 days or more
Frequency of ejaculationMore frequent = longer recovery needed
Overall health & testosteroneBetter health = faster recovery
For many men, especially those over 35-40, ejaculating even 24-48 hours before sex can noticeably delay ejaculation during intercourse.

Practical Tips

  1. Wait 2-3 days before sex if you want to ejaculate closer to average time
  2. Avoid masturbation in the 2-3 days leading up to planned sex - this is the single most effective adjustment
  3. No rigid rule - some men are fine after 1 day, others need 3 days; learn your own pattern
  4. If the issue happens even without recent masturbation, it may be worth checking with a doctor for other causes (low testosterone, medications, psychological factors)

Is This Harmful?

Not at all. Masturbation is a normal, healthy behavior. Adjusting the timing before sex is simply about managing your body's natural recovery cycle - there is nothing medically wrong with you.

Summary: Yes, masturbating the day before sex is a very common and well-understood reason for delayed ejaculation. Simply giving yourself 2-3 days of abstinence before sex should bring your ejaculation time closer to normal. If the problem continues even after adequate rest, consult a doctor.
