Lasting Longer

It’s a fact of life that every one of us wants to last longer!

A satisfying sexual life is an important component of a healthy and happy relationship. Your inability to ‘last long enough’ can also impact heavily on your partner's sexual life and cause major relationship difficulties.

How long should you last?

Let’s get technical here: IELT.

Intravaginal ejaculation latency time (IELT) is defined as the time between the start of vaginal intromission and the start of intravaginal ejaculation.

Marcel Waldinger et al assessed the intravaginal ejaculation latency time (IELT) distribution amongst 500 couples recruited from countries: the Netherlands, United Kingdom, Spain, Turkey, and the United States.

The researchers discovered this:

“the distribution of the IELT in all the five countries was positively skewed, with a median IELT of 5.4 minutes (range, 0.55 to 44.1 minutes). The median IELT decreased significantly with age, from 6.5 minutes in the 18-30 years group, to 4.3 minutes in the group older than 51 years. The median IELT varied between countries, with the median value for Turkey being the lowest, i.e., 3.7 minutes (0.9 to 30.4 minutes), which was significantly different from each of the other countries. Comparison of circumcised (N=98) and not-circumcised (N=261) men in countries excluding Turkey resulted in median IELT values of 6.7 minutes (0.7 to 44.1 minutes) in circumcised compared with 6.0 minutes (0.5 to 37.4 minutes) in not-circumcised men (not significant). The median IELT value was not affected by condom use.”

It all boils down to this:

If you doing at least 5.4 minutes (or to put it in a more positive light, 324 seconds) per session, you’ve got no worries.

Less than this and you are suffering from PE.

PE is not Physical Education!

The medical literature contains several definitions of PE.

Realising that all of these definitions are just authority based rather than evidence based, and have no support from controlled clinical and/or epidemiological studies, Chris McMahon and mates at the Australian Center for Sexual Health in Sydney set out to clarify the murk.

The Aussies analysed the evaluations of the 2007 Ad Hoc Committee for the Definition of Premature Ejaculation (PE) of the International Society for Sexual Medicine (ISSM) on the strengths and weaknesses of the then current definitions of PE, the evidence in support of the constructs of ejaculatory latency, ejaculatory control, sexual satisfaction, and personal/interpersonal distress.

After lots of deliberation (and beer?), all 21 blokes decided to call it a day by agreeing to the agreement of the Ad Hoc Committee that lifelong PE is

"a male sexual dysfunction characterized by ejaculation which always or nearly always occurs prior to or within about one minute of vaginal penetration, and the inability to delay ejaculation on all or nearly all vaginal penetrations, and negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy."

Simply put, if you cum within 1 minute of penetration or you cum before penetration, you’ve got PE!

Calm down! It’s not a problem without solutions.
