Everyone is greedy, selfish, fearful, pain avoiding, pleasure seeking, and ultimately self-interested.

Since death awaits us all, nothing can truly be taken away from us. In life, there is literally nothing to lose. Nature imposes needs. Society sells wants. Most people trade in tomorrow’s success for today’s pleasure. The mind is a battlefield! Some folks go to sleep and wake up tired. Why? They had sleep but no rest. Most folks can’t endure spending a few minutes alone. Yet they expect others to spend hours, or days, or even a lifetime with them. Last but not least: you might as well be yourself, dahling, because everyone else is already taken. 

People are generally more honest and open to suggestion when physically tired, When we hug, biology comes into play, Feelings of “love” are analogous with pain, We are subconsciously deeper affected by moods of those close to us, rather than strangers, Fear of losing one’s cellphone is an actual phobia. 

Polygamous

Take a moment to consider how many men have put their careers, family life and happiness at risk just for a single meaning less, extra marital fling.

consider how in some countries women are stoned to death for adultery, yet the urge to pursue sexual variety outside the lifelong partner has persisited since the dawn of mankind

From this perspective it seems strange that countless individuals in human history have risked their lives and possesions for something that is believed to be “unnatural” to our species.

we evolved in communities where casual sex was the norm : prior to the invention of agriculture just a couple thousand years ago, humans lived in normadic, hunter - gatherer tribes. these societies were tiny, rarely exceeding 150 people. in these close knit societies the obligatory sharing of food, shelter and child care respnsiblities were essential to the survival of the group and its individual members.

sex to was considered a community resource, and both males and females would engage in sexual intercourse with whomever they desired. in other words it was a multi male - multi- female mating system, and it was an effective way to keep people relaxed, amiable and cooperative.

Such societies faded long ago, for the most part. However, the legacy of their promiscuous behavior has been evident in human cultures ever since.

Since the invention of agriculture, many cultures and religions have attempted to diminish our desire for sex and promote monogamy, via strict codes of conduct and harsh punishments for promiscuity. Nevertheless, the human sex drive continues to express itself.

Sexual promiscuity helped our ancestors survive by sharing fatherhood among the group and strengthening social ties.

Because our ancestors engaged in lots of casual sex and had a limited understanding of conception, they had no way of knowing who the father of any given child was. Thus, every male was inclined to care and provide for every child, a responsibility that was distributed among the group. As a result, food and other goods were shared also, improving the chances of survival for everyone.

Casual sex strengthens bonds within the group, because it tends to keep the participants happy, relaxed and amiable. The hormone oxytocin is largely responsible for this phenomenon: sometimes called “nature’s ecstasy,” it is released during sex and produces feelings of closeness and peace.

But wait a second. If everyone was happy sleeping around and shared parenthood is such a great idea, how on earth did we end up living in dysfunctional monogamous couplings, and demonizing promiscuity?

With the invention of agriculture, sexual expression and freedom were severely limited.

Although the standard narrative has been that agriculture was a huge leap forward for humanity, many scientists today believe it was one of the worst things to happen to us. When we began to cultivate plants and domesticate animals, not only did the new, unvaried diet damage our general health, but our social and sex lives suffered a blow: agriculture fostered possessiveness, jealousy and greed.

Prior to agriculture, in their nomadic hunter-gatherer-life, our ancestors had little to be greedy about. They shared whatever food they found, so it wouldn’t be wasted, and because they were constantly on the move, they couldn’t burden themselves with unnecessary possessions.

But then farming created the possibility for humans to become sedentary, and along with that came the idea of ownership and prosperity. As a result, for the first time in history, a distinction between rich and poor appeared, and social problems like hunger and war weren’t far behind.

As human greed was activated, sexual expression and the status of women suffered greatly. The idea of possession, and consequently jealousy, soon extended to sexual relations and family.

For the wealthy farmer, it became important to be certain of which children were his, so that his property would remain in the family after his death. And the only way for the farmer to be certain of his paternity was to force women into fidelity, by public shaming, brute physical force, or legal institutions, such as marriage.

Also, with men doing all the farming, women’s skills as gatherers became redundant, and their role was gradually limited to taking care of the children. As women’s roles became limited to raising the family, the modern idea arose that the female libido is weaker than the male’s – which, as it turns out, is completely untrue.

The human male’s genital anatomy reveals that we evolved in a competitive mating system.

The human penis is, relative to body size, the largest of all in the animal kingdom. Male testes are also large, and located outside the body to keep a large amount of sperm cells at their optimal temperature.

Why?

As you might’ve guessed, these features evolved to perform a specific function in our ancestors’ environment.

First, the size and shape of the human penis and testes evolved out of man’s need to compete with the sperm of many other men, since in prehistory, females would copulate with many men, particularly when they were fertile.

The quality, speed and amount of the males’ sperm would determine whose cells would gain access to fertilize the female. Those men with larger testes, more sperm cells per ejaculate and a better shot were more likely to succeed.

Furthermore, the shape of the human penis, and the thrusting motion during sex, have evolved so the man can literally pump out the semen of previous men. Additionally, the first spurts of semen contain chemicals that protect that man’s sperm from chemicals in other men’s sperm.

And size matters not only in terms of the male genitals, but in terms of the man’s height as well. The height difference between men and women most closely reflects multi-male-multi-female mating.
