saying_yes_2010 is a sex positive art-and-ficbit-athon running its first round in January 2010.
Saying Yes! is a challenge designed to showcase characters who like sex, enjoy sex, and want sex -- characters fully capable of giving informed consent, and giving it enthusiastically. It's about characters who don't view sex or any of its aspects as something demeaning or shameful and don't pass similar value judgments on their partners' choices. There are a lot of stories out there, both fanfic and published, where characters enjoy sex despite themselves, and where a character who takes on a certain role or performs certain behaviors during sex is thought of as weaker or lesser. Sex and sex roles become imposed rather than sought out, and desire is passive, the result of things done to a character rather than things a character actively seeks out and wants.
In contrast, stories and art for Saying Yes! show how being the submissive or bottoming partner during sex is FUN and not demeaning -- and that bottoming and submission are far from the same thing. In these creative works, characters shout "Yes!" instead of "No!," and characters can get up to all kinds of kinky crazy fun without ever being made to feel shamed for their desires.
I will definitely be participating as this hits some issues I find important in the way I handle sex and sexuality in fiction.
