In a somewhat relationship with two bi women

I'm not sure how to explain this but I'll do my best. I have recently become involved in a relationship with two amazing women who were already together. They invited me in as a male part in the bedroom and it evolved into a somewhat mess. The women have had prior mishaps and are not as solid as I thought. Both of them are amazing and balance each other out. The first couple sex sessions got off to a rocky start but we did click. One of the women hadn't had anyone get her off without her having to finish the job herself. The other was the one that I originally started to like. Ok well for the last couple weeks we've been trying to figure out what we're doing and how this works. One of them wants it to work like a threeway couple ( for lack of a better explanation) the other is focused on her partner and says that she is her main focus. I like both of them equally because together they're a cool couple. I am ok with being here for both their needs separated or together. The issue I'm having is I felt they were using me as a weapon to get back at watchtower for stuff in the past. I pointed out that there is a lot of stuff they need to work through and that for this to work communication had to be clear and concise. We agreed that there shod be no surprise pop in when two of us were alone while the other was out. We all agreed to that and then the rules changed. I helped them start talking through some issues but if I hang out with one the other will inevitably try to crash in or pick a fight with the other about something from their past. I suggested that if we are gonna do this that if girl a is with me and girl be comes home the options should be girl a can either join or not but can't ruin or expect sex to stop. But what if girl a wants to fuck and girl b doesn't and we are all together? I don't think this needs to be as stressful as it is. I like both of these women and put myself in the middle by getting involved. I need some advice on how do we make this situation work?

I think the question is what do you want out of this relationship situation? You have to keep in mind that you are the 3rd party in this, they are the couple. It's no different than if it was m/f couple, they have the established relationship dynamic and you are participating when and if they allow it.

If you want to continue in this I suggest you have some more discussion about the situation. From what you describe one partner is focused primarily on the other and explained that is her main relationship, so you need to respect that to make things work. They have to determine what occurs if you are not all together and you will need to go along with it.

If that gives the power of refusal to one party, so be it. It's mutual respect for each other but mainly for their existing relationship. Stress, drama and miscommunication is going to be a part of it if you try to alter the dynamics too much and spend more time with one than the other.

If you're looking for more and it's not working for you I suggest you opt out before it all blows up.

The only thing I can say is what I would do... I'd tell them I don't feel comfortable with the current situation, that I feel like they need to deal with some issues first, and then, contact me again, if they still want to...

Somehow, I'm sure you already know deep down what you should do...
