Here is a brilliant article discussing the use of
alien sexuality as a conflict driver in science fiction.
I agree that sexuality makes for awesome conflict, that studying wildlife is a great idea mine, and that introducing characters from different backgrounds can create long-term challenges that go beyond whether or not they'll ever get together as a couple. Many of my stories that feature romance/sexuality account for cultural or biological differences. "Did You Get Your Answers Questioned?" in
Genderflex was about dealing with a new partner's unfamiliar gender identity. "Peaches from the Tree of Heaven" in
newWitch dealt with divergent reproductive expectations. In
Torn World, my main storyline angles to introduce Fala (a Northern ranger) and Rai (a Southern shopkeeper) as a way of playing out some of the cultural conflicts; and the sexual/romantic arrangements in those two societies are
wildly different. My poetry does likewise. "
The Underground Gardens" presents not a couple but a trio -- a male elf, a female dwarf, and a male (but asexual) human -- and how their family structure influenced their choice of home. One of my unpublished epics, "Courting on the Porch" (currently on sale for $24.25 in the
2010 Holiday Poetry Sale) describes the sexual process of an alien species with
very different sexes, and how that affects their lifestyle.
Among my favorite examples from someone else's work are
haikujaguar's
Jokka stories, some of which are now available for individual download in electronic format. The Jokka have three sexes -- male, female, and neuter -- with varying degrees of durability. Their efforts to cope with their biology are a prevailing force in society; and I think some aspect of that appears in
every story about them that I've read so far.
How does divergent sexuality play into your reading and/or writing?
