As I've said, I began writing over on FFN, and was pointed to AFF to read a fic or two. I also had a few friends from FFN who'd published more explicit work here, and when I wrote my first MA work, this is where it went up.
I'm in the process of cleaning up and posting a fic here that's not at all smut. I've done a batch of oneshots that are no sex. We're about writing, and the freedom to write what you want to write. Adult fiction can engage the mind and challenge preconceptions without always being smut.
Having said that, the smut can be fun as well.
