I agree with StillBehindBlueEyes and Elyse.

It has annoyed me to no end when someone else started making my character take actions. Sometimes I would let it slip, but others I wouldn't. Like Kishi, I've done quite a bit of non-erotica online RPing (though I haven't kept up with it for a couple years). If someone is making your character dance around in circles, then what does that leave you to do? I understand if it was a Dom/Sub story line and the dom would yank back on the subs hair saying something to the effect of = *Suddenly he reaches forward and takes a handful of her hair, pulling back hard enough to stop her from breathing* -- That would be obvious in most cases, that you wouldn't be able to breath with your throat at a certain angle.

I think if you are truly trying to create something then both parties should feel like they are their own character, becoming that character I suppose. To me it's a lot more fun that way
