Man, every time I read your rants I suddenly think "heeey, I could do /that/ with my world too!". I should probably keep some of them free for the entire bloody continent I have very little clue about yet, since there is really only so much you can cram into two linked mountain valleys and surrounding area, but the philosophy idea is really interesting. In part because I've already been experimenting with the different values and ideas that a culture founded by craftsmen would have, e.g. their concept of art and its role in everyday life, and this does tie into that. There's also the truly screwy immortal society... now I'm going to have to bring philosophical debates into the story somehow, damnit.
I already have a few female asexual characters, although considering that people default to sexual unless the opposite is explained to them at length using small words I doubt it'll be obvious in their stories. I'm also not inclined to make a big theme out of it or really address it to that extent, simply because it'd feel like therapy writing/cribbing from my own life and that weirds me out. I think I'm too close to the subject to write about it that way. (Also, making a big deal out of the ex-prostitute's asexuality - although she /is/ genuinely asexual on top of the residual trauma and issues - would probably send the wrong message.)
I do support everyone writing more asexual characters. *waves Visibility flag* There are a plethora of things that an author could write about regarding this, and it saddens me to never see asexuality actually addressed in fiction. I hadn't realised the gender imbalance in possibly-asexual characters, but now that you mention it it does seem obvious and ARGH YES, happy and fulfilled asexual female characters are not an oxymoron and sex, even romantic love for us aromantics, is not the end-all and be-all of existence.
