I met Hubby, S2, and my ex-boyfriend Guy through AdultFriendFinder, which bills itself as an "adult dating" site. In other words, a place for people to find *sex* partners, not necessarily *life* partners.
Clearly I found both with Hubby. We met in May 2008 and were exclusive from that point; we both agreed we wouldn't see other people, and when we married in April 2010, it was a monogamous marriage.
Fast-forward three and a half years, when in response to some incompatibilities in our relationship styles and sexual needs, Hubby suggested we open the marriage. No more monogamy... but at first, the "open" was supposed to be purely sexual. Friendship with other partners was okay; Hubby and I agreed that if stronger feelings developed for someone else, we would cut ties with that person. Each prospective partner was told this up front.
We both used AFF to find other partners. Hubby "hooked up" with one woman and decided the whole thing wasn't for him. That was nearly two years ago now. He's been monogamous, both emotionally and sexually, ever since.
Guy and I started as friends-with-benefits. Two months after he left our area to go home to the midwest, I admitted, first to myself and then to Hubby, that I had stronger feelings for Guy than friendship. I told Hubby that loving more than one man felt natural and right to me, but I also told him I was willing to keep our agreement and cut ties with Guy. Hubby said not to. He was the first to use the word "polyamory", and while he doesn't completely understand how I feel or why, he accepts it. So for a bit over a year, Guy and I had a long-distance relationship. (That ended in October; details are in my blog.)
From September 2013 until last summer, I chose to be with only Hubby and Guy, and not seek any other partners. Hubby maintained his monogamy. Guy, because of the distance thing, found other sexual partners, but chose not to have any emotional involvement beyond friendship. I stayed on AFF, as I had pretty much all along, because I have friends there and I like to chat with them, but I ignored any overtures from other men. And then S2 emailed me.
S2's marriage ended-- in a very friendly, respectful way-- last spring. At the time he and I met, he hadn't been with a woman other than his wife in something like 17 years. He was interested in polyamory; he'd researched it because his wife initially suggested it as a possible way to keep their marriage together, but they'd decided against it. And because he was just out of a marriage and wasn't keen on diving into another closely-committed monogamous situation, the fact that I was married completely worked for him. He went on one date with another woman and told me he felt like he was cheating on me, even though I'd encouraged him. And then something happened as a result of that date that caused him to decide to be exclusive with me. He and I have agreed that his end of our V remains open if he chooses to exercise that option, but right now, he's not exercising it. I'm now with only S2 and Hubby, with no desire whatsoever for any other partners.
So, long story short...
Hubby was initially insistent on monogamy, but changed that because we had some sexual compatibility issues that he felt would be best addressed by finding other sexual partners. (He was right, by the way.) When I developed feelings for another man, Hubby identified it as polyamory and gave me the go-ahead to live poly, but he considers himself "wired" for monogamy.
Guy didn't care one way or another, but because he travels extensively for his job, the fact that I was married to someone else worked for him, because he didn't have to worry about me being lonely or ignored when he wasn't around. He doesn't label anything, but during the time I was with him, he was polysexual, but not polyamorous.
S2 prefers the fact that I'm married because, at this point, he's enjoying living alone, not having to take care of or take full responsibility for another human being, and having the freedom to come and go as he pleases. He's still sorting out whether he considers himself polyamorous or monogamous, but for the time being, exclusivity with me works for him.
As for "like-minded" in terms of how to poly... All three of the men I've mentioned have followed my lead completely. So I guess they're like-minded in terms of "If KC thinks it will work this way and she's happy, we're cool with it." I did have a bit of a rough patch when I tried to explain to Hubby that I'm not okay with hierarchy... Hubby believed he should be my "number one" and Guy my "number two", and I had to make him understand that I didn't feel that way. In my polyverse, no partner is *more* important than another; they're important *differently*. Eventually we reached a place of peace with that when I told Hubby that, while he isn't "number one" over anyone else, he does have a larger *part* of my life by virtue of the fact that he's the one I actually live with. Both Hubby and S2 know I consider them equal as far as their place in my life and heart, and they're both okay with that.
