Since I mostly upload gynomorph NSFW, I was wondering.

Why don't we have a "Gynomorph" tag in the "Characters" section? It only has "Intersex" tags

The upload form includes male, female, andromorph, gynomorph, hermaphrodite, male-herm, and ambiguous_gender as buttons. The option's already there.
As I understand it, though, there aren't any buttons like andromorph/male because it'd make for an absolutely massive explosion of buttons (for our purpose there are seven "genders", seven times seven is 49, versus the 6 buttons that are currently dedicated to pairings).
In an ideal world the upload form would suggest pairing buttons based on what gender buttons you've clicked, but there's no code for that yet.

There's a trick to get quick tags to show up on uploading screen. What you do is add any regular tag like say, artist name, and then you can use quick tags. Adding custom long lists of tags effectively gives us custom 'buttons'. Trying to remember where someone went into more details, but that is all you need to get it working. You can add (or remove) tag buttons directly, using userscripts and other methods.

oh, wait is _that_ why posts will so often have the specific intersex genders but the paring tags are always juat i/i, i/f, or i/m?
