Those are interesting and useful terms, but not really what I need, though noetisexual is closer than sapiosexual.

It's not so much that I'm turned on *only* by words, just that I need them to kick start the process. My natural desire for sexual satisfaction is rather low; I'm not opposed to it, but I feel no real need for it most of the time. If I'm not already in the mood, I *need* the words to get in the mood; physical foreplay doesn't engage my brain enough, so the sexual touch just feels pointless or wrong, sometimes even icky. And I have yet to find a succinct way to describe that.
