I think some degree of bisexuality and polyamory is the norm. I read a theory supporting this many years ago but I can't remember the source (sorry). The gist of it was that most species have an innate awareness of regulating their populations; the herd grows too large and food becomes scarce, too small and it may fail altogether. So reproduction is a factor. But there's also a basic need to develop social orders in most species: colonies, herds, flocks, schools, communities. And that bonding urge goes beyond reproductive sexuality. Or something like that.
Man, being self-aware (most of the time anyway), kind of skews the whole thing because of social mores, religion, and other self-imposed belief systems. So that norm of bisexuality is lost to one extreme or the other because the opportunity exists to allow it to be lost. The 'norm' is arbitrarily decided to be heterosexual because centuries of religious mandates say so, and it's good for supporting a viable worker class. There's a zero-tolerance mentality so anyone that doesn't feel 100% heterosexual has few options to consider other than a complete break with the 'norm', or in other words, a counter-culture develops that supports 100% homosexuality.
Now, before the flames start, all I'm saying is that there's probably a much broader spectrum than what our culture allows for. We've been pushing people to one extreme or the other for centuries and you can't underestimate the effect of that on a society, or species. I have no doubt that there are people that are born inclined to be 100% hetero- or 100% homo- but like most bell curves in biology the vast majority is probably somewhere in the middle, all other factors being equal.
I'll take my own sexual attitudes as an example. When I was in puberty I played with some of the neighborhood boys and girls like many, many people do. Didn't really care what gender they were, I was just curious and exploring the unknown. Then I got older and was solely interested in girls because that was the natural order of things in my specific situation. For many years I considered myself 100% hetero. No way would you have convinced me otherwise. I even had a few MFF situations that I thoroughly enjoyed. Then my wife convinced me to have an MMF thing with her and a friend of ours (hey fair is fair, right?). Surprisingly, I had a blast! There wasn't any touching between me and the other guy, it was all focused on her. But I liked the three way connection just as much as I did in the MFF setting. Then we did it again, and again, and again... okay, finding a guy as a 3rd is much easier than finding a woman. Go figure.
To this day I'm only comfortable with certain limited contact with me and the other guy in these situations. But basically I've come to realize that parts are just parts (cocks are sexy just like pussies) and it's more about the connection of all of us.... the bonding urge, the herd mentality, the community.
Does any of this make sense to anyone? Again, I'm sure there are people that are 100% one way or the other. Born that way. Period. But I think there's a vast majority that are closet bisexual to one degree or another. Isn't it interesting that we have that option on our profiles here?
