Early humans were actually no different from animals, living a life of drinking blood mushroom hair. For us at that time, sexual intercourse with the opposite sex was just for the sake of passing down the family line. And how can one make their offspring survive? As mammals, females play a greater role. Because the fetus needs to spend a long period of time inside the mother's body, and childbirth is also a major test for women. We all know that fetuses mature in the uterus and are then born from the vagina. Everyone has watched it on TV, and during childbirth, doctors often only say force! Force it!, What force is used? Nature is the force exerted by the sphincters on both sides of the female vagina. This is related to whether the fetus can be delivered smoothly, human life is at stake! How did early humans know that women had strong enough muscles?
Hip lifting is the best proof, indicating that this woman has strong enough strength to safely deliver the fetus during childbirth, and the probability of such a situation occurring during fetal death is low.
It is also important for women to have sufficient milk to support their next generation after birth. So, whether a woman has healthy breasts is a major factor in the survival of the fetus. How to judge as a male? The standard is very simple, sharp and full. If a woman has plump breasts, it means she can provide enough milk for her children in the future without starving them to death.
Of course, what was mentioned above is based on early human standards. Nowadays, there are various breast milk substitutes that can also be delivered by caesarean section. Naturally, in the eyes of modern people, the two points are no longer related to the life of the fetus. But in our subconscious, these two points still unconsciously control men's behavior. I once asked people around me, why do you like plump women? Their answers are the same because they are sexy! I asked again, why are plump women sexy? Their answers are vague, sexy is sexy, and why. In fact, this is the default value that nature has set for us since the emergence of humans, which cannot be changed or will not be changed. Humans can reproduce until now, relying solely on these default values.
Now start analyzing psychologically. Women often say why men are not as cautious about sexual behavior as women. I will conduct psychological analysis based on physiological characteristics. Physiologically speaking, the formation of a fetus requires sperm and eggs. A healthy man can generate at least 100 million sperm per day, while a woman's eggs take one to two months to mature. It is obvious that men weigh more than women weigh more. This physiological characteristic quickly transforms into a psychological difference. The sperm consumed by men during sexual intercourse will recover in less than a day, and men will not have to endure the pain of childbirth like women do. Once a woman's only egg in a month is fertilized, the ovaries will stop ovulation, and what awaits the woman will be the inconvenience of conception in October and the pain of childbirth. So, men subconsciously have a reckless attitude towards sexual intercourse because they won't lose anything except for some protein, water, and salt (the main components that make up sperm). Women, on the other hand, are different. They need to put in too much effort, so women have a cautious attitude towards sexual behavior.
As for some women, they may ask why men are promiscuous? The reason may be that these men feel that this reflects their charm and status, or they may simply enjoy it. Some men may ask why I prefer skinny women? This may be related to trends, but for the sake of your descendants, it's better to find a full-bodied version.
