Let’s talk about sex.
Specifically bisexuality. Okay, so there’s more to sexuality than just mashing genitalia together—and what genitalia—which may come as a surprise to you if you’ve just graduated from the Steven Moffat School of Sexxyyyy Ed.
I totally agree with just about everything in here, except for the definition of bisexuality- a lot of bisexuals who identify as such interpret the bi prefix as being attracted to people who identify as a gender different than our own, and a gender closer to our own, as well as the spectrum in between, rather than being strictly attracted to those who identify hard-line male and hard-line female; thus bisexuality can be inclusive of the spectrum, trans individuals, and third gender individuals as well. at least, that’s how I’ve always defined it, and when I was looking into this a bit the other week it seemed I wasn’t alone. Jack’s omnisexuality is applicable because of his universal attraction to everything that moves, but in our limited Earth vocabulary I don’t think its invalid to count him as a bisexual character if, say, there is a poll being done of queer representation on television, as GLAAD did earlier in this year in their regular Where We Are on TV tally. IMO, of course.
