The tag obscured_inner_labia implies vulva, both of which are considered explicit tags. This does make sense to me inherently, but a number of the posts under obscured_inner_labia (and therefore vulva) are rated questionable. Some of these ratings even seem reasonable to me considering the relatively reasonable coverage and lack of excessive indentation of fabric in some of them - as seen in post #5866894, post #4243790, post #3704611. Though, of course, my opinion on these isn't set in stone.
I do believe many of the posts under the obscured_inner_labia rating:q tags should be re-rated as explicit (and I will probably take a shot at it eventually), but I'm curious about the edge cases. Should the tag be removed from them, or should posts similar to those linked above be rated explicit as well? Or any other options. Just want something more concrete for all the genital tags in the questionable rating.
