Legend
As far as I am aware the most sexist thing in L5R is the female only Battle Maidens. Otherwise there is no difference in gender.
And the expectation that a female of the Samurai or Royal social castes is accompanied by a yojimbo at all times when not at home. I'm not digging out 2E to quote page numbers.
Plus, no male geishas (I've not seen reference to them in L5R at all), most of the female NPC's are either courtiers or shugenja. There are some Samurai-ko... but even that is an interesting quirk of Japanese - -ko is used to indicate any of "female," "Child," "Little," or "Small."
It's mentioned in the 2E Player's Book that the gender issues in Rokugan are toned down, but not erased. Just enough to keep a samurai feel... in both directions. (Historical Nippon was much more complex.)
In general, if male/female doesn't have any impact at all on things, I can't maintain enough suspension of disbelief to enjoy the game. It's too far from What People Are Like for me to be able to keep that world in mind. I keep replacing it with one that makes more sense to me.
Then again, I submit that the issue with your games being gender focused is yours. You have gender biased expectations, and you demand they be met in games you play in. Please, don't play at my table, because, either I'm enforcing historical ones, or I'm not paying attention to character gender.
You're the one with the issue, and the problem.
