Why only humans don't have a fixed period of estrus?

Animals are in heat only once or more times a year. Animals have sex, one is to give birth, the other is to regulate their bodies. People are different. People can have sex at any time, even though their childbearing time is fixed. We still don't know why people do this. The characteristic of sex without a fixed period of estrus brings happiness and endless annoyance to human beings. If there is a fixed period of estrus, men do not have to go around the kiln like Ximen officials after having three wives and four concubines adult toys , nor do they have to occupy the beauties of the world like the emperor but can do nothing about it. And not so many people have the urge to rape.

It is precisely because human beings do not have a fixed period of estrus and can have estrus or have sex at any time, so human beings have sexual morality. For the first time, man covered his lower body with leaves. Man's invention of clothes also comes from the cover of the lower body. Now many people think that people can go back to basics and act naked. It's a good idea, but it's naive. They have no idea why humans wear clothes. Is it to keep out the cold? This is only a secondary idea. Several great sexual revolutions in human history are carried out because of the extravagance of the sexes. Human beings are different from animals. Animals have no intention to think about sex after they disappear in estrus. However, human beings are different. Their brains are full of sexual symbols.

Some people think that this is the result of brain development, because what distinguishes people from animals is that people have brains unmatched by other animals. Long-term repeated sexual intercourse practice makes sexual intercourse a well-trained activity that fills the brain with sexual content, and he knows what to do even if certain stimuli fail to stimulate him. As it is passed on from generation to generation, the sexual content left in the brain becomes a sexual signal that often works and becomes a genetic factor, and the female's estrus gradually disappears.

This explanation seems quite reasonable. Because people will naturally ask, why do so many animals do not go beyond the limitations of the creator in evolution and still have a fixed period of estrus? Humans think it mainly lies in the brain. People have such brains, but animals don't.

More anthropologists and physiologists believe that the disappearance of female estrus, like breast bulge, is a camouflage and deception performed by women on men out of the need for survival and the need to protect future generations, which has been "deceived" for millions of years. So "make the fake come true," and it's what it is now. This is an extension of Darwin's theory of sexual selection.

It has been found that in some primates, there is a phenomenon of killing offspring. For example, in a species of long-tailed monkey, the male monkey is usually the "concubine 3000", but often powerful male monkeys invade the territory and occupy the "harem," killing all the offspring of the previous male monkeys and wiping out the roots. In this way, the new king can have all the female monkeys, waiting for their estrus, and he can continue his offspring. In such a dark autocratic background, if the female monkey is already pregnant with a child, she will pretend to enter a "false estrus" so that the child is born. After millions of years of repeated training, estrus basically does not exist.

This Monkey King mentality seems to have been inherited in human beings. Once the emperor ascended the throne, the first thing he thought of was to possess the beauties of the world. So in the autocratic period, the emperor represented the pinnacle of desire.

The disappearance of estrus is accompanied by a human physiological tissue. This is the hymen of the woman who has been arguing about it for a long time. Human beings can't help but wonder that the creator not only gives human beings a sexual body without a fixed period of estrus, but also places women with a hymen that allows men to grasp the handle. Why is that?

Sociologists often explain this in terms of Darwin's sexual choice. However, people have not found any structure similar to the human hymen in chimpanzees, gorillas and orangutans. Is it possible that humans created it in the process of evolution? Following this line of thinking and sexual selection, anthropologists speculate that the hymen must have developed after humans "broke up" with apes, and even calculated the exact time: about 4 million to 40, 000 years ago. They believe that the origin of the hymen is probably a secondary birth defect, like webbed fingers or toes, and the hymen is less useful than the cecum or tonsils, but in body semiotics, the hymen may be a symbol. it may be the result of the sexual choices of jealous, possessive men in the past, which they want to ensure a woman's chastity and confrontational betrayal. The male ancestors of human beings were only willing to provide for virgin brides in order to increase the chances of their genes being passed on to future generations. The bride has a hymen g spot vibrator , and her daughter's offspring tend to have a hymen, so men can continue to make "sexual choices" for women with hymen until all the little girls are born with that little film. From an evolutionary point of view, the hymen is the result of human "sexual choice".

This explanation is obviously far-fetched. At the beginning of human birth, until the rise of patrilineal culture in the Neolithic Age dildo shop , it has been in matrilineal society. During this period, women have far more sexual rights than men, and there is no need for such camouflage. In fact, it is probably a kind of physiological tissue brought about by the birth of human beings, not the result of evolution. It's just that later men like to use it to control women, and this is after men began to have the right to sexual choice.



Editor's recommendation:

The biological clock of sexual desire of men and women in a day.

The time from 6: 00 a.m. to 8: 00 a.m. is expected to enjoy high-quality sex, and the feeling of holding back urine after waking up in the morning increases women's desire for sex. The study found that having sex at this time of day is the easiest time to get the best part of the pleasure, but the tight schedule in the morning often makes it impossible to express your passion.

When a woman's sexual desire comes, there will be four small moves.

Research shows that when a woman's estrogen levels rise, she blinks an average of 32% more times per hour than others when she wants the attention of the opposite sex. Especially in front of masculine-looking members of the opposite sex, this feature is the desire to get each other's attention.
