If you're not a scientist, after a short sex you might wonder at the end of the bed, how long usually sex lasts?
A scientist may be formulated in the same question with a more abstract terms, namely: How the average time it takes to get the intravaginal ejaculation?
I understand that sex is more than just the effort of inserting the penis into the vagina so the ejaculation, but other things related to sex is not always easy to define (kissing? rub?). To keep this discussion to keep it simple and specific, we will focus on the time of ejaculation.
Measuring the average time for ejaculates rather than things that can be done directly. Perhaps you think what if ask people how long they need to ejaculate? There are at least two major problems in such an approach. First, people tend to bias on the long time in estimating the timing of ejaculation, because socially you expected can last all night.
Another issue is people usually did not know how much their time when having sex. Not usually people intercourse while watching the clock next to the bed, and it may be difficult to estimate the time when love-making without assisted others.
What studies show?
The best research so far calculate the average ejaculation time at 500 couples from across the country that calculates time fuck them for four weeks by using a stopwatch.
Sounds weird, just press the Start button "participants" at the time of penetration and pressing the button "stop" when the ejaculation. You may think this will ruin the mood, and did not fully reflect the natural thing. But science is rarely perfect, and research the above is the best we have found so far.
So what do the scientists find? The most surprising results indicate there are many variations of the time. The average time it takes each pair (taken on average during their sex) ranges between 33 seconds to 44 minutes. That means the difference between 80 times
So it is quite clear that there is not a normal amount of time to measure the intercourse. Even so, the average time of all the couples that is 5.4 minutes. This means if you lined up with a pair of 500 which has a short time to long, a couple that is located in the middle of the lineup have average time 5.4 seconds when they do it.
There are other things that draw from the above research. For example, condom use does not affect the time factor, so too does the prianya never been circumcised or not, who are questioning the old understanding that circumcision effect on penile sensitivity and sexual relationship with durability.
Country of origin of the pair also have no effect, except if they come from Turkey that his relationship is very short time (3.7 hours) than any other country from couples (Netherlands, Spain, United Kingdom and the United States). The other thing that's surprising is the fact that the older spouse, then the shorter the time bercintanya, in contrast to common understanding (which may have been made by an older man).
Why should we old have sex?
As a researcher of evolution, all the talk about how long does sex last a makes me wonder: why sexual relationships also require time? All intercourse is aiming to enter the sperm into the vagina. And create what it Rookery movement in bed? Instead of inserting and removing the penis hundreds of times when the intercourse, why not include it only once and thereafter we can spend our time drinking lemon?
Before you answer, that it is fun, keep in mind that the process of evolution do not care about the things that are purely fun; evolutionary process of designing everything becomes fun just because he's helped our ancestors pass down their genes to future generations.
For example, although we enjoy devouring food, we are not going to chew food for five minutes just because we love it. It will make feeding becomes inefficient, and we evolved to understand that chewing food for too long, it was disgusting.
Why do we make love for long is a complicated question and there is no answer, but the instructions might be located on the form of the penis itself. In 2003, researchers found — by using the vagina, penis, sperm and artificial — that actual penis head tip take sperm that was previously present in the vagina.
This shows that the penis backwards movement over and over again actually aims to remove the sperm of another man before finally ejaculates, the sperm to ensure that they first arrived at the egg. This then explains why men feel pain when they pushed his Dick back entrance after their ejaculation, because it means that movement risky to remove the sperm of their own.
So what needs to be done with this information? My suggestion hadn't thought too while being fuck.
