Is it realistic to be monogamous?
If we mean realistic for the species of humans, then the answer clearly is yes. In various cultures around the world people are able to engage in lifelong monogamous relationships.
Monogamy is an intrinsically unstable mating strategy. Benefits include the (relative) certainty of access to the partner's reproductive potential, but the chief disadvantage is that access to other potential partners is strongly diminished, particularly in those cases where males exhibit strong mate-guarding behavior.
Anderson argues that monogamy enforces “jealousy scripts,” which fade over time in open relationships. Sex with others is also certain to create emotional attachments that undermine the primary relationship—and the dignity of others.
According to conventional wisdom, women are more likely to want a monogamous relationship because we're more interested than men in establishing an emotional connection. Men, on the other hand, simply want sex, sex, and more sex, which, the theory goes, explains why dudes just aren't built for monogamy, babe.
Monogamy, after all, does not come naturally; it is not the norm unless a society enforces it as such. There are immense benefits to doing so. But it is unclear how well we humans can achieve this aim in the present environment.

“The human mating system is extremely flexible,” Bernard Chapais of the University of Montreal wrote in a recent review in Evolutionary Anthropology. Only 17 percent of human cultures are strictly monogamous.
The PNAS paper, which analyzed 230 species of primates, concludes that protecting the kids is the greatest benefit of male monogamy. By sticking close to his mate a male reduces the risk of infanticide.
As long as the relationship is ethical, considerate, and considerate, being monogamous is not selfish. If couples are accepting and open-minded, there isn't a wrong or selfish relationship. Put simply, you shouldn't worry too much about what others think and focus on discovering your truth.
People are wired in different ways, and what they want from a relationship can differ, too. Both polyamorous and monogamous relationships are perfectly normal.
Are polyamorous people happier than monogamous?
More recent field research on a large Canadian sample also found that those in open or polyamorous relationships were just as happy as those in monogamous relationships. The Rubel and Bogaert review reports that most non-monogamous people are just as or more sexually satisfied than monogamists.
The human male body provides ambiguous clues to the answer but the balance of evidence indicates that we are biologically inclined towards monogamy while retaining an urge to "sleep around".

John Gill comments on 1 Corinthians 7 and states that polygamy is unlawful; and that one man is to have but one wife, and to keep to her; and that one woman is to have but one husband, and to keep to him and the wife only has a power over the husband's body, a right to it, and may claim the use of it: this power over ...
So, from the perspective of evolutionary psychology, monogamy is natural because fathering is natural in the human species and fathering only evolves with sufficient sexual exclusivity to allow for paternity certainty for men and sufficient resource provision certainty for women.
According to the New York Times, a 2011 paper showed that early humans, or hominids, began shifting towards monogamy about 3.5 million years ago—though the species never evolved to be 100% monogamous (remember that earlier statistic).
Monogamous men were more likely to experience any degree of erectile dysfunction and depression. Odds ratios and 95% confidence intervals for erectile dysfunction and depression were 14.4 (95% CI: 3.1–67.5) and 7.4 (95% CI: 0.9–61.9), respectively.
To some people, one partner at a time makes them feel like they can't explore their sexuality or romanticism to the fullest. Ethical non-monogamy allows them to explore their sexuality while still being fully committed to one person. They love more than one person at a time.
Just like you can be committed to multiple friendships, you can be committed to multiple romantic relationships as well — and there's nothing wrong with being single, whether you identify as monogamous or not!
Recent discoveries have led biologists to talk about the three varieties of monogamy: social monogamy, sexual monogamy, and genetic monogamy. The distinction between these three are important to the modern understanding of monogamy.
In Brief. Even in societies where polygamy is permitted, monogamy is by far the most common human mating arrangement.
Are men biologically polygamous?
In essence, men are only socially monogamous rather than genetically monogamous.
By mating with more than one male over the course of her lifetime, a female gains higher genetic variation among her offspring. The benefits of monogamy, which are shared parental care and territorial resources, are maintained by having only one mate at a time, or by concealing extra-pair partnerships.
For humans, monogamy is not biologically ordained. According to evolutionary psychologist David M. Buss of the University of Texas at Austin, humans are in general innately inclined toward nonmonogamy. But, Buss argues, promiscuity is not a universal phenomenon; lifelong relationships can and do work for many people.
Humans are now mostly monogamous, but this has been the norm for just the past 1,000 years. Scientists at University College London believe monogamy emerged so males could protect their infants from other males in ancestral groups who may kill them in order to mate with their mothers.
This means that of all marriages, 58 per cent are monogamous. Only men in the top 10 per cent of status married more than two women. The most wives that anyone has is four.
“The human mating system is extremely flexible,” Bernard Chapais of the University of Montreal wrote in a recent review in Evolutionary Anthropology. Only 17 percent of human cultures are strictly monogamous.
Balance of evidence indicates we are biologically inclined towards monogamy. Science has yet to definitively pronounce on whether humans are naturally monogamous (lifelong male-female breeding pair) or polygamous (single male breeding with more than one female).
Summary: In cultures that permit men to take multiple wives, the intra-sexual competition that occurs causes greater levels of crime, violence, poverty and gender inequality than in societies that institutionalize and practice monogamous marriage.
Many people are not fulfilled in monogamous relationships, and instead pursue other less conventional relationship styles, like polyamory or throuples.
Toxic monogamy, as defined by Hillary Berry in her article “Toxic Monogamy Culture,” refers to “monogamy as a cultural institution [that] has been interpreted and practiced in ways that are unhealthy.” These ideas are often romanticized or perpetuated in media, cultural norms, and social expectations.
How common is swinging in America?
The best evidence suggests around 4 percent of adults. That may not sound like many, but it means one couple in 25. If you know two dozen couples, chances are one participates in consensual non-monogamy (CNM), also known as “open” relationships. Put another way, 4 percent means some 2.8 million U.S. couples.
Monogamy is difficult to maintain. Sure, it's easy enough at times when your life is devoid of temptation. But unless you and your partner live in isolation in a cottage in the woods, there are no guarantees that an attractive “other” will not emerge — to lure you away and challenge the sanctity of your relationship.
Monogamy is a relationship with only one partner at a time, rather than multiple partners. A monogamous relationship can be sexual or emotional, but it's usually both. Many modern relationships are monogamous. But even if they want to be with just one partner, some people have trouble staying monogamous.
