What lore do you ignore?

[Cleretic]

It's been five thousand years since Allag dunked itself into the ground in what by all appearances was a continent-wide earthquake. That's a lot of chance for knowledge to get lost, especially considering the fact that they were by all appearances a very centralizing nation, and that nobody liked them, including their own citizens.

Basically all it would take to lose a huge bulk of Allagan knowledge after their fall is one modestly successful generation of 'let's return to the earth'. They had a lot of institutional knowledge (including knowledge of how to read their own surviving records; computers aren't as easy to use as, say, a book) that would've been lost, and once that's gone it's leagues harder to retain.

The women we see in Sastasha, the post moogle quest of stroking the haft, many female npc speech bubbles in Limsa hint to said activities. The Ninja quest Ninja Bathin'.. The mamool Ja that you beat up in the fate Peeping Ja. His "dance" is implied to be more about what he wants to do with some of the female Miqo'te bathers. Also Haurchefant, Aymeric, Zenos and any other npc that can be seen as flirting with the WoL don't care about their gender. Magnai and Daidukul being rare exceptions. As Magnai only wants to flirt with you if you're female and well all Buduga only want to interact with other men.

Yeah, that's a pretty workable starting list. I was going to mention the Ul'dahn merchant making some very unsubtle threats to the Ala Mhigan woman outside the Quicksand, and in a more indirect form there's the numerous bastard children in Ishgard, but other than that you've got most of the big ones.

If we're going whole-game the other big one to mention is Yotsuyu, but I think the game's approach to the subject becomes very different sometime around when Kazutoyo Maehiro left to do FFXVI; Yotsuyu is emblematic of a very different era.
