Monogamy was not something I was interested in the first time my symptoms got really bad.
Actually, self control of any kind wasn't something I was interested in.
For me, that was my bottom line. Eat, drink, be merry... For tomorrow we may die.
There were other pieces that went into it (no self control); sex, fighting, etc. are all super-duper grounding for me, so they majorly moderated my symptoms; major trust issues; emotional issues; control issues; etc. And those were / are important. But the living every day as if it's your last? Sounds good. Lives badly. I was very, very wild for a long time. First because I had no self control. And then because I didn't want it.
I gradually did learn self control, because there were -eventually- things that I wanted in my life, and they required self control in order to get them. But it took quite some time to learn the first time around, and then the second time around it was just as hard to relearn it. Although, to be fair, I've gone about relearning self control completely differently this time. Instead of just saying f*ck it and going full tilt boogie, I threw on the breaks completely. With both I've had to work my way slowly towards the middle. The other way was faster and a lot more fun. This way creates one whole helluva lot less wreckage.

As far as monogamy as a sociocultural construct? I've spent far too much time in cultures where 1:1 isn't the natural order of things, to view 1:1 as the natural order of things ;) What I've come to believe, however, is that without the cultural norms backing up individual practice? "Good luck with that." Meaning it may not be impossible, but it is exceptionally difficult to maintain, much less establish. I think there are probably several norms in which I could be happy, though. As long as my bottom line/ personal preferences/ need-wants in a relationship are met. And that? That's the hard part! Regardless of whether it's monogamy, or polygyny, or polyandry, or casual dating, or f*ckbuddies, or whatever. Like minds & like hearts, aligning need/wants.
