Viera culture and sexuality

[Fenral]

Because I know entirely too much on the subject: it is a proven fact of the natural world that sexually-reproducing species, especially those wired for recreational sex, engage in homosexual behavior (sometimes exclusive, sometimes not, so just like humans really). Said behavior, while not procreative, does strengthen the bonds between members of the same sex, contributing to the overall fitness of the herd as whole and, consequently, the continued evolution and survival of the species.

So I'd say yes definitely for females, but probably no for Word-following males if only because their Jedi training apparently leads to them interacting with nobody at all most of the time. (This will be amusing at 6.0 when ~80% of the gay male playerbase goes bunny.) Heterosexual monogamy is probably not really a thing (much like nunh), but depending on fertility rates and longevity, could be sustainable in some cases. All of this made more sense when males were supposed to be treated like they don't exist at all. Should've just gone with the Galka explanation...

tl;dr: it wouldn't be unnatural by any objective scientific metric, but we will also probably never get lore that says otherwise, regardless.

(A tale of forbidden romance between two wood warders would be totally up my alley though.)
