I also want to do something about my "very vague smut" and "smut" tags. I might rename it to "sex" and let the rating speak for the vagueness or otherwise. Let me know what you think.

Now that I think it over a bit, I do like this idea, too. I think "vague" is kind of, well, vague. I think just labeling them all "sex" then letting the rating speak for the level of detail and depth works better and helps the readers know exactly what to expect.
