I don't know where some of you cats get your BS, but I'd like to point out a couple of things....
1. There is PLENTY of scientific, biological, historical, and anthropological evidence that human beings' "natural state" is not, in fact, to have 10+ fuck buddies, or even more than one. There seem to be people who are super into polyamory and/or promiscuity these days, who it really seems like to try and vindicate their own personal lifestyles by believing that "humans are naturally promiscuous". I hate to burst the hedonistic bubble, but there is more than enough evidence that points to that not being true, even in so-called "caveman times".
The vast majority of known, recorded human societies, had institutions of marriage and nuclear families going on. That includes most Native American cultures, African cultures, Asian cultures, ancient European cultures, etc. etc. People seem to love bringing up examples like ancient Greece and Rome, but against I hate to burst the bubble, but that was more the exception of ancient Europe, not the rule. Rome especially was widely known for their levels of hedonism and excess, but more importantly, even in ROME, that was more the exception, not the rule. Meaning, that just like with most societies, there was a huge difference between how the rich ruling minority class lived, and how the vast majority of actual Romans lived. MOST Romans did actually get married, and were fairly monogamous and family-oriented, much like their Italian descendants. Why? Because monogamy, marriage, and focus on family, just like the vast majority of other human cultures out there, were important cornerstones in what for most was a fairly hard-working, agrarian lifestyle.
Furthermore, while humans are often compared even to modern apes, as far as known, recorded history shows, human beings tend to be far more monogamous than pretty much all apes. Some of the oldest known societies, even ancient Syrians and Sumerians, had marriage and societal focus on nuclear families. More than enough psychological evidence exists to show that human beings are actually fairly hardwired to "pair bonding", IE mating for life, and mates staying together not only while raising children, but long after the children are grown. Some try to claim that this is purely "societal norms", nurture not nature, but it's mighty ironic that literally almost EVERY single human society and civilization, has had marriage and a focus on family, in SOME way. There are exceptions, but there is a strong argument to be made that, regarding "human nature", polygamy is more the deviation from our nature, not the adherence to it. While the idea that "humans naturally want to mate with as many people as possible to deepen the gene pool" may sound neat to some on paper, frankly it doesn't hold much water in the face of not only maternal, but natural paternal instinct hardwired into us. The way humans are built, in a more natural, primal setting, females tend to NEED the protection and help of males both when pregnant, and when raising children. Men that fuck and flee, do not exactly fit that bill, and humans likely would not have survived into the modern era if that was how we were wired.
I'm not saying it historically DIDN'T happen. It absolutely did. But that it was naturally, biologically, and culturally, in MORE cases than not, the exception, not the rule.
2. The use of the word "Pagan" is kind of silly to me. Just as one example, when a lot of people use the word "Pagan" these days, they think of people like the ancient Celts, because a lot of "Neo-Pagans" draw heavily on what is known of ancient Celtic culture for their views and beliefs. What IS known as about ancient, pre-Christian Celtic culture, is that they did, by and large, have a fairly monogamous, marriage-based society. In fact marriage was an important part of their culture and traditions. That isn't to say, again, that polygamy or promiscuity DIDN'T happen. But only to say that it wasn't the norm that most Celts subscribed to.
The implication also seems to be that society is moving away from "Christian values", thus becoming more "Pagan", and thus becoming more promiscuous. I find that insinuation insulting on many levels. For one thing, I myself AM "Pagan", for lack of a better word, and I do mostly draw on ancient Celtic views, though not completely. For another, the idea that somehow Christianity has a monopoly on monogamy, marriage, or non-promiscuity, is laughable. As previously stated, marriage and monogamous relationships have been part of MOST human societies, dating back many thousands of years before Christianity was a twinkle in anyone's eye. Secondly, while "The Bible" does indeed feature men with multiple wives, that was not generally the norm in Hebrew/Jewish pre-Christian culture either. Nor is it typically (while not unheard of), the norm in Muslim culture. And good lord, if you want to talk about "conservative", prude, ANTI-promiscuous (at least in belief) religion and culture, don't just point at Christianity, because Islam has that shit on LOCK. And there happen to be some billion or so Muslims in the world. So given that, I'd hardly say that (mostly American) Christians are the only ones shaping world views on sex and relationships.
Ultimately, while I find it kind of funny, I do wonder why this was even brought up. If some of you entertain or seem to like the idea of "fucking around", well then....go for it. I'd suggest it isn't the healthiest attitude (or practice), but live how you want, so long as you aren't hurting anyone. But please, enough with the "it's in human nature to have sex with lots of people", because honestly, not only is that to this day a highly contentious idea, but it also has plenty of evidence that it simply isn't, nor ever has been, true.
