Unlike premature ejaculation, delayed ejaculation is a less common male sexual problem. Some may not even consider it as a problem!
Delayed ejaculation occurs when one takes more than 30 minutes to ejaculate (or does not ejaculate at all). Severity of delayed ejaculation can be grouped under
1) Mild – able to experience orgasm through vaginal intercourse, but under certain conditons
2) Moderate – not able to ejaculate during vaginal intercourse, but able to ejaculate using other form of stimulus (e.g. oral intercourse, masturbation etc.)
3) Severe – inability to achieve orgasm / ejaculate under any circumstances
Causes of delayed ejaculation include:
1) Psychological – unusual masturbation pattern, past traumatic experience, unattractive partner etc.
2) Physical – previous injury to spine, pelvic injury or surgery with nerve injury, blockage of spermatic duct
3) Hormonal – low testosterone level, low thyroid hormone
4) Medications – certain anti-depressants
Treating the underlying causes (especially for low hormones or delayed ejaculation secondary to medications) help with the delayed ejaculation. For psychological cause, therapy would be necessary (such as sexual counselling and therapy or even hypnotic therapy).
