Do you really think I'm interested in living out all my sexual fantasies no matter how perverse?
First of all, I must point out that this is an odd question to ask in this circunstance. You are implying that threesomes with bissexual people are inherently and remarkably perverse. Such is not even remotely the case.
I do expect you, like much anyone else, to live your sexual fantasies to the extent that you have the opportunity, that you can do so within reasonable parameters of physical and emotional safety, and that in so doing you all respect each other.
I don't think that is too much to hope for, and I certainly fail to see why that would rule out experiences with bissexual people.
I really take issue with the implication that it is "perverse" to want to be in a relationship with a bisexual person. Here is hoping that after some reflection you might decide that it is not a proper or accurate thing to say. I certainly think so.
Those are pagan ways, not Christian. Ultimately I've already lived out many of my sexual fantasies and found them pretty unsatisfying in the long run. I'm not deluded enough to think that chasing down my bisexual fantasies is going to be the thing that fills me with what I really need or want.
I thought the Christian way was to perceive all people as equally helpless and insignificant before God, and therefore to love each other in a fraternal way?
I truly don't think that involves denial of one's own sexual fantasies, particularly at the expense of respect for actual people.
You may be genuinely attracted to bissexual women and threesomes, or you may not. Either way is fine, as is not being certain. it is even fine whether you decide to pursue the matter or rather to settle into the safety of a known situation; fantasies are not always significant and important, after all.
But to belittle people and treat them as less deserving of respect because they are bissexual, women, willing to express their sexuality, not repulsed by the idea of a threesome, "pagan", at peace with fantasies that you claim to find unsatisfying despite raising them on your own or any other such silly reason,
that is a bad sign.
