There have been several solid studies over the past 15 years concerning the time it takes for men to ejaculate during sex. The reason this is important is that it helps doctors, men, and women know how to define premature ejaculation.
One study titled measured how long it took for men (from The Netherlands, United Kingdom, Spain, Turkey, and the United States) to orgasm and ejaculate after their penis was inserted into the vagina, called the Intravaginal Ejaculatory Latency Time, or IELT. Foreplay was not timed and no same-sex couples were included. They took note of condom use and circumcision.
The results were fascinating. The average was just about 6 minutes with men from Turkey having the shortest time (4.4 minutes) and the men in Great Britain having the longest time (the longest IELT) (10 minutes).
Condom use and circumcision were not factors and the men who felt that they didn’t last long enough lasted 5.2 minutes.
It seems that usual times of vaginal penetration are not that much longer than for men who suffer from premature ejaculation, which can be defined as lasting as many as 3 minutes.
In another study, men who experienced premature ejaculation (PE) were asked to measure the time it took for them to masturbate both in a medical office and at home. The time it took for them to reach orgasm was compared to men who did not experience PE. The reported times for men with PE was 3.42 minutes and for men without PE 8.84 minutes.
This last estimate is probably the most reasonable approximation. Knowing what is typical can help define what is not typical, what might be considered Premature Ejaculation (PE).
