Hmm? I've known older woman who've only had one sexual partner; their husband.
Given the history of Western civilization, where losing your virginity out of wedlock ruins you and committing adultery can end in your death, I wouldn't be surprised if there have been many monogamous people throughout the centuries.
Jeez, you're making it sound like monogamy is a punishment and everyone would be polyamorous if it wouldn't end "badly" or something. There are people who enjoy monogamy, you know. Or maybe you don't know. And again you've ended up speaking for the entire world. "Most people". Again, you're wrong. You don't know what "most people" want or do. When will you learn that?
As for the thread I'm in agreement with the Cullen guy. This has gotten way out of hand. And while I originally was in favor of having a few polyamorous options in the game, I'm becoming more cynical about it myself. Seems most of the vocal supporters for it here are ones who are wanting inclusion for inclusion's sake, and not for the sake of realistic character development. I am fine with the inclusion of any romantic option such as this, but as long as it makes sense. As long as it contributes something of value. Heterosexual, homosexual, bisexual, asexual, transsexual, polyamorous, monogamous, whatever. I'm fine with it. But if people simply want it to be coded in and simply want it included for the sake of feeling included, while not providing any logical background for it or any reason of value for it to be included, then no, I don't want it in, because it dilutes and clogs everything else. Even heterosexual monogamous relationships; I don't want many of them, unless they can provide value and substance to the world and its character, not just a "We need inclusion so let's include it" sort of deal. I want these things to matter, to be important, not just some extra line of code and dialogue tossed in for a character for no reason.
