Animals are gene delivery and propagation vehicles.
Females have to invest a lot of time and resources to produce one child.
They tend to be attracted to what they perceive as a high genetic merit individual.
Males can produce numerous children if they can convince enough females to do so. Males therefore can tend to have sex with a wider range of individuals than females as the burden of producing children does not weigh as heavily on them. There are of course pair bond tendencies evolved in humans.
Back in the '' caveman days or through much of human history, it was better to have two parents stick together(within the wider tribe). It led to greater success in raising children to child bearing age than if the female was left on her own.
These pair bonds can of course weaken over time.
The strength of humans is their weakness.
They found greater survivability by having some degree of pair bonding and by uniting into small tribal and family groupings.
Long ago, if a man was an island, he likely ended up starving or being killed by predators.
Of course men and women may break the pair bond either covertly or overtly in some instances to mate with other high worth genetic individuals(in their eyes). There can be a possible genetic benefit conveyed to any subsequent offspring.
To induce people to procreate, sex is pleasurable for most people, so it can be the be all and end all for some, but in evolutionary terms sex evolved as a means of reproduction and as a way to shuffle different combinations of genes into the next generation.

10,000 years of Middle Eastern civilisation and the place is not at peace but rather in pieces.
