The sites not big enough to warrant tagging projects (or maybe it's in the perfect spot to be able to cover everything)

male -1_male -multiple_males

female -1_female -multiple_females

unknown_gender -1_unknown -multiple_unknown

Plus since I'm responsible for 99.9% of uploads and literally made the tags, everything should be more or less consistent within a margin of error
The more regular users that actually upload be get the more some tag cleanups will be needed

I've considered adding an androgynous tag (alongside masculine & feminine, anologus to ambiguous) so that theoretically every post should have one of those three, making finding missing posts easier
