The interplay of quantity and quality: Analyzing the Coolidge effect and the truth behind male emotional burnout
Female animals don't readily accept males. While this may seem like a passive or negative attitude towards mating, it's actually a way for them to buy time to assess the male's suitability. Male animals aim to leave behind as many genes as possible, leading to a relentless courtship of every female they find. Female animals, on the other hand, are temporarily unable to mate after a single mating, thus requiring careful evaluation.
Males prioritize quantity over quality, while females prioritize quality. Many wild birds have illegitimate offspring, not because females are promiscuous, but because the males who come to court have better genes than their mates, thus winning the female's favor. For humans, however, a woman's success hinges on a single egg. Considering the issue of having children, the quality of the partner's sperm is crucial. These factors must be carefully examined.
When men flirt, women often respond with a series of negative statements. But in reality, these responses are buying them time; they are evaluating the man's qualities. Of course, you probably don't realize you're judging him. The neocortex, the thinking part of the brain, which humans evolved, is the most significant characteristic that distinguishes humans from other animals. Therefore, the union of men and women involves highly complex emotions, far more complex than simple animal unions.
From a biological perspective, the instinct to leave behind healthier offspring is undeniable. Males prioritize quantity, while females prioritize quality-this is true even for humans. I often hear women lament, "After marriage, the frequency of sex suddenly decreases..." Men are often described as creatures who "don't give bait after they've caught the fish," but if this is true, why is that?
Spending too much time with the same person can lead to boredom. However, this issue is also closely related to the biological nature of male animals. Have you ever heard of the "Coolidge Effect"? People who have ever kept chickens or hamsters in pairs may have noticed this phenomenon: when males and females are first put together, they mate frequently, but soon the frequency of mating decreases.
I've also noticed that keeping a rooster and a hen together inevitably leads to a gradual decrease in their mating frequency. After a while, it's almost exactly like a human couple going through a period of sexual burnout-the rooster completely loses interest in the hen. This might seem like the rooster's energy has waned, but if a new hen is introduced at this point, the rooster immediately becomes excited. Once it considers the new hen as a potential partner, its sexual drive surges again.
The decrease in mating frequency is not due to decreased male stamina or reproductive function, but rather to male instinct. Always facing the same mate fails to satisfy the instinct to "spread their genes everywhere." Therefore, they need new mates. Male animals are such creatures. From animals to humans, this common phenomenon of the "Coolidge effect" can be seen in all sexually reproducing organisms.
Human males often "stop feeding once they've caught the fish," a phenomenon not necessarily due to boredom with their wives, but rather explained by male instinct. This is because even increasing the frequency of intercourse with the same partner cannot spread their genes more widely. Among the many reasons for male infidelity, the differences in male and female reproductive organs and their impact on sexual behavior cannot be ignored.
When discussing male physiology, the sperm accumulated in a man's body must be constantly released. Young men are able to have sex daily because their bodies have a strong sperm-producing capacity, and the epididymis-the sperm storage container-quickly fills up. Penis erection occurs because of sexual arousal. This mechanism can be broadly divided into central erection and reflex erection. Understanding these physiological facts helps in understanding male behavior.
