Tagging rules for intersex and ambiguous characters

Just to be clear, I don't want us to be super picky about tags - IMO as long as it's understandable, anything is okay. However, Pokémon yiff has a pinned thread talking about this, and I've been PMed asking how to tag something. Basically, even if we don't want to enforce it, it might be useful to have some standard as a guideline.

Many communities reference the tagging rules of the main !yiff community, which includes tags for male and female. However, it does not specify rules for characters that fall outside that spectrum, or whose gender is unknown (due to being obscured, for example). This has resulted in tagging being a bit ad-hoc (e.g. [H], [I], [G], for gynomorphs), and might feel a bit exclusionary for a site that claims to be "queer".

Just as something to propose, how about we update the tagging rules to be something like this (to be similar to e621's gender tags):

• [M] For male characters.
• [F] For female characters.
• [G] For gynomorph (feminine character with a dick but no pussy).
• [A] For andromorph (masculine character with a pussy but no dick).
• [H] For herm (character with both a pussy and dick).
• [U] For Unknown/unclear.

This would also mean retiring pairing codes ("G" for "gay", "S" for straight and so on) in favour of "M/M" and "M/F".
