One of them just hit me with, "What about guy, guy, girl?" and I know the other ones will soon be asking it to.

Now this is a complete doubt standard but I don't have any interest in another guy, for one I just don't swing that way and two, It just seems... not right coming from my frame. These girls are all down for being completely dominated, like tied up and forced pleasure and it just seems like allowing another man in would effectively be relinquishing a bit of that dominance which is instinctual why they are so attracted to me in the first place.

Oh and for context, there is little rapport between us because I have yet to meet these girls, it was via tinder and no they are not catfishes because I had them send plenty of confirmation pics.

So the question is, how do I handle this/explain this stance? Do I go with the evolutionary explanation on women being left alone together in caves while the men could be gone for days or weeks hunting so they adapted to being use to being with other females. Do I go the more logical route and just explain that she is attracted to me because I dominate her and I'm not going to allow another man to do the same, which is effectively dominating her even more?

Here is the txt and how I've handled it so far
