There are several ways that profligate sex can impact children.
1) To start with, people have a unique microorganism culture on their bodies, as distinct as a fingerprint. It is denser and has a greater number of pathogens in the “coliform zone”, from about the knees to the navel. (This is the real reason that it has long been suggested that you wash your hands after going to the bathroom.)
When people have sex, there is an enormous transfer of new types and strains of microorganisms between them. This is why when women lose their virginity, they often develop yeast infections, their immune system having difficulty fighting all these new infections simultaneously.
If people remain monogamous, this is usually no problem for more than a short time. Couples quickly develop similar cultures. However, with multiple sexual partners, people develop “supercultures” of microorganisms on their bodies that can opportunistically impact a person with a simple culture enough to inhibit their fertility. It is unknown what impact having “superculture” parents could have on the development of fetuses and infants.
2) Animals use a great deal of energy in reproduction. In some cases, even a lethal amount. People are unique both in having sex for its side effect of pleasure, and in assuming that sex is not taxing to their bodies. Often in strongly denying the fact. Young people, especially, believe they have the three “I’s”: they are impervious, immune and immortal.
Many people do not have enough energy to ever reproduce, and some have such limited energy that they cannot even have sex without serious consequences to their health. Reproduction has strong effects to both females, and it is now being learned, males.
On top of everything else, raising children is very energy intensive. More and more couples are abandoning sex entirely after having children. This is why I say it is such a critical issue that women, especially, are permitted to use their energy in child rearing, instead of to raise national productivity for free, their extra income being taxed away.
Reproduction is a very complex and difficult biological process, made more so with social and economic factors, and other stresses placed on reproductive age adults. The US was fortunate after WWII to have an explosion of suburbia, based on the Levittown model, which created the ideal situation for a baby boom.
Using it in contrast with life today, we see how they succeeded in producing children, where we are failing.
“Many people do not have enough energy to ever reproduce, and some have such limited energy that they cannot even have sex without serious consequences to their health. Reproduction has strong effects to both females, and it is now being learned, males.”
Sorry, I just don’t see this. I know that some people are just too tired any given night, but serious consequences to their health if they have sex? Don’t believe it.
“More and more couples are abandoning sex entirely after having children.”
I don’t doubt that many people have less sex after children for many reasons, but no sex? Not among folks I know.
“This is why I say it is such a critical issue that women, especially, are permitted to use their energy in child rearing, instead of to raise national productivity for free, their extra income being taxed away.”
Eh?
