I think it would be difficult to tag based on context since often we can't know a character's personality, story, beliefs, identity, etc... just what we can see. At least most of the time.
In this case, the terms 'andromorph' and 'gynomorph' literally translates to 'male form' and 'female form', and I believe that it is referring to the physical sex instead of gender, especially since 'form' in this case is alludes to the physical representation of the character.
What I'm trying to say is that the terms 'andro' and 'gyno' refer in this case to the physical sex and are translated as 'male' and 'female'. In this sense it would make sense to use [M*] and [F*] since the original [M] and [F] tags are also related to physical sex instead of gender, since the gender of a character can't be determined by just the character's physical traits. A character with breasts and a vagina might very well be the fursona of a trans male furry and he feels it better represents him because it's closer to his physical appearance.
Wait a second....

Okay, I think I got it.
Here's the definition for the term 'prime' used in mathematics:
"In mathematics, the prime is generally used to generate more variable names for similar things without resorting to subscripts, with x′ generally meaning something related to (or derived from) x. For example, if a point is represented by the Cartesian coordinates (x, y), then that point rotated, translated or reflected might be represented as (x′, y′). "
Thus the most respectful way of tagging andromorphs and gynomorphs could be [M′] and [F′], since it does indicate that an element such as a function in mathematics is derivated, differentiated but by no means does it indicate that it's inferior in any way. Technically the prime character ′ is it's own character but I think that using apostrophes will suffice.
I would still like to campaign for [G'], [S'] and [L'] because I think it's a way simplify tags when there's 3+ characters. Most of the time when you browse yiff what matters to you is the orientation of the characters / scene, instead of the amount of characters by counting the number of Ms and Fs.
Thus, how about this:
- [M], [F], [M'], [F'], [I], [A] for solo pictures
- [M/F], [M/M], [M/F'], etc... for two characters The above categories probably encompass the vast majority of yiff and they're easy to understand. Then we relegate group tags such as [G], [L], [S], [G'], [L'], [S'], [Bi], [Bi'] ONLY for pictures with 3+ characters as an optional representation that can save you from having to write many letters and making searching and filtering easier. (G-L-S-Bi notation would change from being discouraged for pictures with just two characters where two letters can give us full precision at a minor extra cost of a single letter and from now on only encouraged for pictures with 3+ characters)
In this case I realize that some precision is lost, but pictures with 3+ characters aren't the majority, it's optional and it could be tidier in many circumstances where you care about the orientation.
I think we might be getting close to having a solution? What do you think?
Damn, if that's the case, how and where can I please surround myself with cybersecurity experts? Please... for security purposes of course.
