David Letterman, LeAnn Rimes, Kris Jenner, Bill Clinton, Tiger Woods and Kristen Stewart are several public figures that have proven that in their own lives, monogamy has not been realistic. The catch phrase, “Monogamy isn’t realistic,” can be heard on a scene in Judd Apatow and Amy Schumer’s recent movie, "Trainwreck." The scene takes place on the hood of a car with a portrayal of Schumer chanting the phrase as a child in unison with her younger sister.

Monogamy is defined as “the practice or state of being married to one person at a time; the practice or state of having a sexual relationship with only one partner.” An article on CNN asked the question, “In the age of hookups, friends with benefits and online dating, and as human life expectancy grows, is it still reasonable to expect people to pair up and stay monogamous until death do them part?” Do I believe that today’s society will rigorously practice monogamy in relationships? No. Do I believe that it is possible to practice monogamy in a relationship? Absolutely.

With movies, songs, books and television shows that promote sexual promiscuity, it is easy to fall into the trap of thinking that "Fifty Shades of Grey" is an acceptable lifestyle, and that it is not human nature to have sexual relations with only one person throughout an entire lifetime. I agree, it is NOT human nature to devote the act of sex to one partner, because human nature is SINFUL. The explanation that I have for why monogamy is indeed sensible is because in Mark 10:8 the Bible states, “And two will become one flesh; so they are no longer two, but one flesh.” God did not say three or four, but ONE. God showed that polygamists, people who practice having more than one wife or husband at the same time, in Bible-time did not benefit. Abraham and Jacob's acts of polygamy created disharmony amongst their families. The custom of polyamory (being romantically involved with more than one person at the same time), polygamy and promiscuity stem from instant sexual gratification, and more often than not end with personal conflict.

Psychiatrist Judith Eve Lipton stated, “There are a lot of reasons why sexual monogamy is in people’s interests, because whether it’s raising children or avoiding emotional chaos and drama, building an estate and avoiding conflict about estate planning, there are lots of reasons that two people who cooperate are better off than one person alone or one person who is a cheat.”
