As a single twenty something, I subsisted on stories of sexual exploits. Brunch with friends consisted of dishing the dirt on what happened the night before. All of our experiences seemed like some kind of amazing movie, where the hot musician/artist/stranger from out of town walks in and sweeps away the night with his own unique way of wooing, either leading to mounting sexual tension or strewn sheets.

I also worked at a brand new restaurant where they only hired you if you were beautiful or Irish. Everyone was sexy. We worked hard, played hard, and then all ended up in bed together. To be honest, it was the best job I ever had, with the strongest sense of community. The drama kept it interesting, and persistent flirtations kept my adrenaline pumping. People with commitments didn’t fare so well working there. But I had no strings, no attachments, and just a couple of obsessions. I was at that age where you were allowed to be just a little bit stupid. I learned that you probably shouldn’t mix business with pleasure, but it’s a lot more fun when you do.

Ten years later, I look back on that time as my heyday of singledom. It was an adventure to sleep with all kinds of men, and I’m glad that I did. I learned a great deal about life from all of those experiences. I never imagined that my life would change so much since then, and that I would choose to be in a monogamous marriage.

We’ve both admitted that the single thing we miss most about dating is the variety. Once married, that excitement of the brand new person in your arms is a thing of the past. The challenge is to go beyond the familiar to create a fresh erotic experience. Biologically, the familiar is a warning signal that keeps us from committing incest, and once your family, there is nothing more familiar than your spouse.

At times, we get our kicks from listening to stories told by our single guy friends. But as they talk, I find myself feeling depressed and left bored. They check young girls off their list, and are consumed with looks rather than substance – the type of girls who like to flip their ponytail in your face; had a boob job at eighteen; and fail in conversations with comments like, “Alcohol was once illegal? That never happened!” In the meantime, the fully formed human beings are relegated into friendship territory.

For much of our lives, love and sex are two very different things. If you marry a person based on your passionate sex life, you’ll wake up one day to find that you have nothing in common. If you marry your best friend, you’ll realize that as love grows stronger, keeping sex fresh is a challenge. Love and sex only come together completely in the first initial phases of an intense relationship, and as familiarity takes over, lust wanes.

Everything that I’ve ever felt about the nature of human sexuality is explained and affirmed in Sex At Dawn – How We Mate, Why We Stray, and What It Means for Modern Relationships by Christopher Ryan and Cacilda Jetha’. As their theory goes, we owe much of our culture to the rise of agriculture, but the earth was a more balanced place when we remained hunter-gatherers in pre-history. There was no famine, no malnutrition; people grew taller and lived longer; finding food took up to three hours a day leaving the rest of time for play; when food and resources were scarce they kept moving; and communities were kept small so that everyone could be accommodated for. Strength came from how little you had – as in possessions as well as people. Greed represented failure, and sharing was the ultimate benefit. As food was not withheld, neither was sex.

During ovulation, women slept with as many men as possible, letting the best sperm-match for her egg battle it out inside her body. The baby could be anybody’s, and this ensured protection for the child. Everyone took responsibility for raising the children. There are many communities throughout the world that still function in this way, though outside pressures threaten to stamp it out.

Our bodies perform functions that are basic to this mode of sex and reproduction. As a woman vocalizes during orgasm in the throes of sex with one man, she is calling attention to other potential mates in the area. When a man thrusts, his action combined with the coronal ridge of his penis creates a suction that removes competing sperm from a woman’s vaginal canal. A woman’s body will actually attack sperm that are not the right match for her egg. But when sperm and egg are the right match to make a strong and immune child, her body is more welcoming. These various functions are called “sperm competition.”

There is a lot to be learned in this regard from our primate cousins. With Gorillas, the largest male wins all the females. He competes with his strength, but his scrotum is tiny – an example of male competition rather than sperm competition. With bonobo chimps, the females lead with a sexually free society, where the males can enjoy themselves instead of posturing to win the ladies. When there is enough sex to go around, everyone can relax.

Most social primates are non-monogamous. In fact, it’s a real stretch to find any animals anywhere that are monogamous. I hate to burst the bubble, but even penguins find a new mate after the hardships of protecting the young are through. Sometimes penguins engage in threesomes that are beneficial for the male in times of keeping the egg warm – double duty.

Of the primates, gibbons are a standout for their solitary existence up in the trees, with a generally monogamous existence. Among the gibbons, males and females are exactly the same size. Humans have much more in common with chimps and bonobos in regards to male/female size ratio and the general size of male sex organs. We also share 98.8% of the same DNA.

As a social function, sex throughout history has been a solidifying exercise between people groups – a way to create bonds, establish friendship, welcome distant travelers and gain their trust. Marriage, on the other hand, was a negotiation – an economic and political maneuver. Typically, patriarchs chose who you married, before the Victorian era built up the idealistic idea of marrying for love. That same era was the most uptight, restricting, and repressive time. No one thought that women actually wanted to have sex. They were idealized as angelic creatures, all the while getting their orgasms at the doctor’s office in treatment for Hysteria.

“Otto Kiefer, in his 1934 Sexual Life in Ancient Rome, explains that from the Roman perspective, “Natural and physical laws are alien and even opposed to the marriage tie. Accordingly, the woman who is entering marriage must atone to Mother Nature for violating her, and go through a period of free prostitution, in which she purchases the chastity of marriage by preliminary unchastity (Ryan, Jetha, 124 – 125).””

Sound advice. There is a reason why “gang bangs” are such a popular porn feature. The truth is, it takes us back to our roots in the ultimate expression of sperm competition. Monogamy has caused an increase in fertility issues in men – some 20% of men suffer, and the numbers are rising. These issues would never arise in a non-monogamous society, where the strongest sperm win, weeding out the weak. In monogamy, the weak just keep trying.

A man’s sexual preferences become rigid in his youth, while a woman’s preferences are infinitely flexible (whether she knows it or not).

“Gay or straight, the men were predictable. The things that turned them on were what you’d expect…. The female subjects, on the other hand, were the very picture of inscrutability. Regardless of sexual orientation, most of them had the plethysmograph’s needle twitching over just about everything they saw. Whether they were watching men with men, women with women, the guy on the beach, the woman in the gym, or bonobos in the zoo, their genital blood was pumping. But unlike the men, many of the women reported (via the keypad) that they weren’t turned on. As Daniel Bergner reported on the study in The New York Times, “With women… mind and genitals seemed scarcely to belong to the same person (Ryan, Jetha, 273).'”

Despite the major shift in consciousness through the last one hundred years, women are still very good at being sexually dishonest with themselves. And why wouldn’t they, when society at large anxiously awaits that moment when they can label a woman a slut or a whore? Women are still punished for being sexual, when it should be celebrated.

I’ve never fared well with overly idealistic women. When they ask me to tell them how I met Michael, how he proposed, where we got married – I cringe a little bit. They are all great stories, but they sum up our relationship into some bizarre fairytale narrative that has nothing to do with our day-to-day reality. Those stories are mere blippits on the radar at this point. They remind me of the whirlwind that I was swept up into, left almost unrecognizable to myself, as I planned a wedding and turned into a girly girl, entering into a mainstream institution.

I’m still confused by what, exactly, happened to me. I’m still difficult to deal with, yes, but my personality did a back flip in response to Michael’s triple lutz. He made me a better person. I became strong and secure, simply because he believed in me so much. And now, five and half years since we met, we’ve changed so much together that I have little in common with the person I was back then.

I know that I could handle an open marriage, but Michael is not interested. And would I want to go back to that way of life? I see the other options out there, and it all pales in comparison. Before, so much energy went into thinking about sex, when now, we put our energy into the work that we love doing. I was not that productive before Michael came along.

We have a shared narrative that makes life enjoyable. Sometimes we get stuck in a rut, and sometimes we forget to have sex for a few weeks, and at other times, he feels more like my brother or my son or my father than a husband. But then it all comes back around, and it’s like we’re at the beginning again, in our own little world, with the sheets in wild disarray, and the hours passing by undetected.

I think the important thing is to not look at a relationship as a given. To not give up on life and let everything go. It’s the outside world that keeps the inside world invigorated. It’s the community at large that keeps love alive. An insular relationship is doomed to end in boredom. With trust and openess, fresh energy flows, and you find that the person you married never stops changing.
