I'm bisexual. Sometimes I seem to want mostly females, occaisionally I go through boy-crazy phases. On the whole I consider myself primarily oriented towards women, but compatibility of soul and spirit is more important to me than physical attraction, and there are more men who are compatible with me, it seems, than women (come on, where are all the female nerds?)
Blood, of course, knows no sex, any more than soul. Souls reincarnate in bodies of different sexes, all of which of course have blood. Female blood is not different from male blood, to me, except that every drop of blood has the traces of an individual in it, and individuals have their own peculiar feel; part of which involves sex. What I guess I'm trying to say is that sexuality, for me, is a lot like blood lust - so long as I find a compatible partner, the chemistry is sufficient. Aesthetic considerations or primary orientation seem rather less important. I have definite preferences, but I am quite willing to look outside my primary preference, or be open to possibilities. I'm an opportunist. It helps me get what I need, both emotionally and in terms of blood.
The only thing that I really can't do without is emotional connection. It hurts terribly not to be involved with my lovers and donors. I get nothing out of the transaction; it's cold and meaningless. I'm too damn romantic for my own good. That aside, I can pretty much be open to various alternatives.
However I have yet to meet a lesbian vampire. That was not a rude or ill-willed comment, just the truth from my own experiences. For a while, I had a screen name on AOL known as "BiVampire" - a self-humoured take off on the book "I, Vampire". But it fit me none the less!!
*grin* They're out there, believe me! (Pat Califia comes to mind, although she too is slightly bisexual in certain circumstances) Think of the statistics, though: lesbianism is a minority sexual orientation. At most, it accounts for five percent of the population (if you want to trust Kinsey's statistics). Vampires are even less common. I think "one in a million" is a fair guess. What, then, is the likelihood of one stumbling across a Kinsey 6 or 7 vampiress? Um, I'm not good at maths, but it's...pretty damn low. They exist, but are a VERY tiny and probably invisible minority. Something like that came up on the PrideGoth list recently - we were kind of snarking about the low incidence of lesbian goths.
