I'm the kind of RPer who really doesn't talk to people all that much OOC about what I want from my scenes, or my relationships, or the direction I'm looking to take my character in. My general philosophy is what happens, happens, and part of the fun is the mystery of it. Its not to say I can't be coaxed into talking about these things, its just that I never initiate them myself. The only exception is re-made relationships in which you need to have a common ground of understanding to portray said relationship accurately going forward (whether that relationship is romantic or sibling of parent or friendship or hated enemies).
As an extension, I don't really think I've ever discussed what I want out of a TS scene. I've never asked anyone if they want to bump the uglies in text. Often what I write isn't even what would actually get my knockers off properly, which is not to say I'll not get aroused. Its just, you know, personally I don't find blood spraying everywhere to be particularly sexy, but if I'm playing a vampire they rarely get all that interested unless you offer them blood, too. And if my character has gotten drunk as part of the foreplay, it should shock nobody if he (occasionally she) falls asleep, or abruptly has to run (stumble and fall on the way) to the toilet.
Anyway, I do know I like certain styles. I like sharp descriptions (as opposed to the vague 'she got naked'), I like it blunt and to the point action. I don't like endless flowery rants or internal monologues of this is the best and its love and wow lets go to heaven together. I'm very okay with temporary awkwardness and things getting derailed.
I can count on one hand the amount of times I've actually TSed over the last year, though. That by itself keeps things a bit fresh, I suppose. I will quickly use FTB and one-post summaries, or make it all about the sexposition (thank you GoT for that word!) if the sexytimes come in too rapid succession. If I portray a relationship often a scene set will be post coital, so the sex is part of the background, but you know, its already done so lets get our clothes back on and focus on the story going forward.
