Good point. The tag Ikamusume alone has more than a thousand posts, approximately one fourth of the tag tentacles (about four thousand posts). So, relying on "tentacles" and the rating alone would not return optimal results.
Not all of the Ikamusume posts are tagged with tentacles, so it's less than one fourth. Only a handful of Ikamusume posts are explicit too, so there's no major problem with using ratings really.
Personally I don't like like the idea of tagging Ikamusume pics with tentacles unless her hair are actually behaving tentacle-y (i.e. restraining women, slipping into orifices, or depicted realistically enough to be tentacles beyond any doubt). I just think there's too much of a visual difference between a "tentacle" as in post #1021603 and one as in post #1021417.

I still support keeping tentacle sex and filling it with the applicable posts.
Cleaning Ikamusume up the way I described above would probably be a lot easier than going through all tentacles posts to populate tentacle_sex. Whether that would be more appropriate though, should be discussed and decided by people who are more qualified than I am. This is just my opinion.
