I saw something as I scrolled my flist the other day and I didn't think much of it, and I could be even misremembering what it really was, too. But it was something to do with Challenging yourself. Ficwise. Write something you've never done before.
And there's not much I've not done. Scat and vomit play maybe and I'm not very interested in the former and the latter is a triggery thing for me. I'm not sure whether I've written watersports, but I know I have beta-read it. *shrugs*
For the most part, if I wanted to write it? I've written it. If I was so-so on something, I've written it or something like it. If I'm squicked by it, there's a fifty percent chance I've written that stuff, too.
So, for me to think of something challenging, it'd be pointless. Though, I admit that one of the hardest things for me to wrap my brain around to write is monosexuality. It's really hard for me to comprehend what it's like to have no sexual interest in either men or women.
It's probably why I usually write from the pov of someone bi.
Certain types of genres are tough for me, too. Like fluff/schmoop. (Though I got a Schmoop bingo card, because I can't write angst all the time.)
I think the difficulty in the light things is that my favourite ever romance is Wild Adapter. (not that it's a romantic thing) Just volume six, guys. Volume six. The I love you so much I will shoot everyone in the fucking face to get you back. The shot of Tokito holding a gun twists my heart because he's not a killer. But they tried to kill Kubota and that's not okay and the Kubota steps behind him and they hold the gun together. Guh. Yeah, so this is my favourite sort of love. Horribly dysfunctional and desperate and unhealthy, but undeniable and til death.
