First Things First

Hello.
I'm M.B.
I've recently joined an afianced couple, to become their third and begin our polyamorous relationship. I'm a unicorn. Which is the colloquial term for a person, usually female, who is willing to be exclusively romantic and/or sexual with both members of a dyad.
For the sake of their children and any future careers the three of us might persue, I'm going to abbreviate names to J (wife), K (J's first child), L (J's and M's first child together and second child to each, who is yet to be born), M (husband), and Mj (M's first child.)

Yes, J, K, L, M, Mj, and MB. Right? It makes me smile. So many M's.

I suppose this blog will be about the interpersonal connections, family life, solutions to the problems that turn up, and just in general slice of life. And also very poorly ordered, because I'm very bad about thinking in jagged shards of everywhere. 

 I called the blog Cellular Polyfidelity because a cellular family is a vernacular term for a three-or-more adult family. The term is based around nuclear family (two adults and their children), and polyfidelity is faith to all the members of the relationship.

But since this is the beginning, and we seem to be headed into fairly uncharted territories, and my nature is one of a thinker and a writer, I chose to start the blog. I am later going to attempt to get both the adults in on it, and maybe even the children once they learn to read and write and type. If they won't post, I'll definitely get data and permission to share aforementioned data.

I'll let them post how they feel about polyamory themselves and let them decide to say why exactly they were looking for a third, or ask permission later, but for me-- polyamory's always just made so much sense to me. The extra help alone with children and money and cooking and cleaning and errands and-- just life in general-- seems like it would be very useful, and that's not to mention that you can get some things from some people (certain kinds of emotional support, sexual favors, someone to talk about the other person with) that you can't from a single mate.

For the initial contact... For the three of us, it was an accident, really. We met on fetlife, a fetishist social media site, where one can post all kinds of pictures and fictions and meet all kinds of people from all sorts of lifestyles. It's mostly BDSM-related, but there are furries, transsexuals, transvestites, asexual, genderqueer, polyamorous, monogamous,
The two of them had been together for about a year, and had been not-very-intentionally seeking a third. I'll ask if they want to announce the reasons later.

I have some erotica (okay, fine, porn) I've written and posted onto my page, the quality of which M appreciated.
And so he messaged me to talk to me about it, and he and I started to write back and forth. I expressed some interest, as did he (after I started it, I confess. I'm a horrible flirt.), and then I contacted J, because that's a part of the rules in my book (you don't hit on one member of a couple without hitting on the other one!), and I quickly won her attention, too. (Again, didn't realize how strong I was coming on, but I wouldn't change it upon retrospect.)

And within... say... two weeks? I think, of initial contact with M, they invited me over for the weekend, basically to be a first date.

The weekend was lovely. The bonding happened quickly and easily, even the kids got used to me quickly, and I learned a lot about them each, in their habits and their parenting methods and who they are. And so far, it has only gotten more intense and more wonderful.
I returned the following weekend, and the next one, and I brought her home with me (we still live apart), and we've started to take action to live together. We're hoping to establish a spot where I won't have to couch monkey soon.
They call me Second Wife (because she has a woman she's been calling her wife since second grade or something). And we're working on what the kids can call me. I think we've decided on Ima, which is Yiddish for 'mother', and doesn't sound too much like Mom.

At first I was rather ambiguous about joining the relationship. First of all, it was a commitment that I couldn't take lightly. due to the children.
And then M went to a girl's house and I got territorial, and when I get territorial, I determine it's time to put up or shut up.

We've determined that we're closed. (there are a lot of things that can also be used to call us what we are; exclusive, polyfidelitous, 'fluid bound', a series of other things.) Closed poly, being that there are the three of us and only the three of us. (Also the two point five kids.)

We're working on moving in together, and then, hopefully, the adventure will really begin.
Thanks for stopping by. Take care.
