How long does sex generally last?
Brendan Zietsch , an associate professor of psychology at the University of Queensland, Australia, explains 'general sex duration,' which many people secretly care about but are difficult to find out.
Many people have wondered, 'How long do ordinary people have sex?' During or after having sex.
How long does sex normally last?
Scientists rephrase the question, 'How long does normal sex last?' To 'What is the mean intravaginal ejaculation latency time?' The average vaginal ejaculation latency sounds difficult, but in simple terms it is the 'average time from putting the penis in the vagina to ejaculation'.
Of course, sex isn't all about putting a penis in your vagina and ejaculating, it also includes elements such as kissing and foreplay and actions during insertion, but researchers simplify things from insertion to ejaculation. Focuses on time. But simplifying sex time from insertion to ejaculation is not easy to study, Zietsch said.
Questionnaire surveys are the most data-collecting method for investigating mean vaginal ejaculation latency, but there are two problems with this approach. The first is that people may report the duration of sex longer than they really are because of the social belief that 'it is better to have sex longer'. Second, many people don't check their clocks at the beginning and end of sex, so they don't know how long they actually had sex.
study Zietsch says it says. In this study, we conducted a stopwatch when having sex with '500 couples who have a stable heterosexual relationship for more than 6 months' living in the five countries of the Netherlands, the United Kingdom, Spain, Turkey, and the United States. I had them measure the time. The experiment continued for four weeks, and each time the couple had sex, they measured the time from insertion to ejaculation with a stopwatch, and also recorded the presence or absence of circumcision and the use of condoms.

Analyzing the aggregated data, the average intravaginal ejaculation latency of each couple varied greatly, with the shortest couple taking 33 seconds and the longest couple taking 44 minutes, an 80-fold difference. did. Therefore, Zietsch points out that there is no fixed 'general sex time'. In addition, when arranging 500 couples in order of average intravaginal ejaculation latency, it seems that the couple who came to the center was 'about 5 minutes 24 seconds', and if you say it strongly, 5 minutes 24 seconds is the median value of all couples. It becomes.
The study also found that the presence or absence of condoms and the presence or absence of circumcision did not affect the average intravaginal ejaculation latency. Results contrary to the idea of 'becoming longer' were also found. In addition, while there was no difference in average vaginal ejaculation latency between couples in Western countries, Turkish couples had a slightly shorter median of about 3 minutes and 42 seconds, and older couples had sex time. I also found it short.
Of course, the act of 'measuring time with a stopwatch during sex' may have affected the mood or failed to accurately time, but this study has so far average vaginal ejaculation latency. Zietsch says it was the most researched on.
study showed that 'the shape of the penis is suitable for scooping out the dripping liquid in the vagina.'
Based on the idea that 'sex is to leave offspring,' the real need for sex is to send sperm into the vagina. Therefore, it is most rational to insert the penis into the vagina and ejaculate immediately, and there is no need to repeatedly insert and remove the penis and continue having sex for a long time.
Zietsch points out that the clue may be in the form of a penis as a reason why sex has evolved so that it doesn't end with just one penis insertion into the vagina. A 2003
This result suggests that the act of repeatedly moving the penis in and out has the function of 'scraping the semen left in the vagina by another man before ejaculation.' By putting the penis in and out before ejaculation and scraping out the semen of others, it may be easier to fertilize with your own semen. Zietsch also said that the reason why moving the penis after ejaculation is painful may be to prevent it from squeezing out your semen.
