Poly relationships can work when you have the right individuals.
I've attempted a poly relationship, I flew up to meet them back in march. He was a sensual dominant named David and Tracy was a 'mommy' domina who loved to be pampered/
I was very happy and loved by both of them, in fact, things were going so well that we were planning a live in situation and they were going to get a larger house to accomodate me. They were awesome people. though it did fall out for reasons I dont really feel like getting into. We're still on good terms, and if a similar situation were to arise and I was single, I would love to do it again.
Its all very situational. My friend Mike wanted me to be a sister sub to his current submissive and it drove me up the wall. I said no. She drives me insane. He's one of my really good friends, and I can handle either her OR him, I Like her when hes not around, but when theyre together it makes me want to puke. So when we all tried playing together I get bored, annoyed, then irritated. It just would not have worked in the least. So I stopped playing with the two of them. He somehow thinks this is because I'm straight. Ha. I've decided to let this go rather than create an argument that could risk our friendship, its that much of an issue with me.
You have to learn what works for you. With a couple, you Have to take the pair, no one or the other. I'm a jealous girl that craves attention and affection - I know this and can foresee a situation where my jealousy would become an issue.
I'm not attracted to submissive females, but I loved having a Domme while it lasted. I miss her very much. Ive also realized that serving With other subs leaves me disinterested, which is why having a Dominant couple over a Dom/sub one works very well with me, I can spend my time serving one or the other, and as the 'pet' of the two, I become a very happy girl =)
Its certainly not for everyone, you have to know yourself, be Honest with yourself, have an idea of what youre getting into.
