[Kaira]
Ziel - it gets even more fun when the relationship is between two identity clusters (legal entities/summative minds that contain multiple dissociated identities) who both pretty much all identify as demiasexual/demisexual to fully asexual, varying by identity, and don't even acknowledge the shared body as being any of theirs, ie, being fully species-dysphoric. Our avatar-bodies are direct expressions of our identities, artistically created yet also engineered works that show and express who we are, and in that context 'what we are'; however we also acknowledge that we are actually just identities, data encoded into neural states and whatnot as well, ie, we are anchored in the reality of what we actually are.
As far as we are concerned, Love is purely something that stems from Emotional Intimacy - the capacity to completely open one's self up to another, to care for their well being and perpetuated existence as a discrete identity, and sacrifice for the sake of the others. Sexuality does not enter into it.
Quite simply, we don't need sex, the promise of sex, or even the desire for sex, in order to have our relationship. It can be used as one of many possible expressions of love, but in no way, shape or form is our relationship founded, driven by, or otherwise contingent on sex or sexuality. In fact, the very notion of "love" that is contingent on sex or sexuality to us (the Kairavan cluster at least) is both incomprehensible and repulsive. Its insincere - from our perspective, its A LIE, plain and simple. Because its not truly and completely about the other person. For the other cluster, its more painful than repulsive, but still as much a lie, because they've been hurt many times in the past by people falling in 'love' with them only to leave them when they discovered they were not going to be able to sexually love them back.
On top of that, given our identity-driven detachment from our shared bodies, our identity-genders or lack thereof may completely not align with the shared body's as well, let alone species (no alignment in any cases here - heck, our Thavdyn is a machine for crying out loud). AND EVEN THEN we have no preferences.
And although we have plans to live together, its not about sex at all, rather about being able to look out for and care for each other. Heck, um, to be entirely honest, human bodies at least for me.. especially this one (for I guess obvious reasons), are.. a little disturbing...
And... our relationship is even more atypical to those in your society, but I think I've rambled on enough for now..
