Takmar and xtauh have a long, inconsistent, and extremely complicated history with gender identities and modes of sexuality that are not what most would consider “normal”. As with humans, many cultures consider the latter to be a basic fact of the universe, deviation from which is anything from confusion to an illness to a moral evil; but, also as with humans, this either ignores or actively discounts the presence and prevalence of what we might today call LGBT+ individuals, as well as the more nuanced positions of other past and present cultures have had toward them.
Though sleeping around is no less common among homosexual and bisexual takmar and xtauh than any others, committed relationships tend to be limited in scope; that is to say that while heterosexual females may have many husbands, and heterosexual males may occasionally have more than one wife, the more permanent same-sex relationships tend to involve two people (especially if they are female; males will sometimes form triads). The reasons for this are not clear, though certainly a factor is likely to be the ease of noticing a larger same-sex group.
Over the broad sweep of both species and their histories, it is a general truism that there are lighter consequences when males engage in same-sex relationships than when females do.
On the one side, males are under less strict 'official' supervision. As part of a nomadic band, they are most often in areas where the only significant form of social control is provided by the band itself, and many bands are fairly tolerant of behavior that does not threaten them. Within a settlement, they may be more closely observed, but in general their sexual or romantic behavior stands a decent chance of going ignored so long as a wife (whether one's own, or someone else's) is not being slighted by it. A particularly broad-minded female may even, sometimes, be willing to marry both male members of a homosexual relationship, especially if they are likely to be economically valuable; the males will be camouflaged as part of a traditional family, and will get to have a home and the experience of raising children, while their wife will have their assistance and labor in her household, even if her children must be fathered by someone else.
Males often live in groups, so no one notices if they remain close to each other. With little to no acknowledgement of biological paternity, physically fathering children is not required to blend in. Females have neither such solace; they usually do not live with other females other than close family members, and they usually live in societies where femininity and status are linked to fertility. Either childlessness, or cohabiting with an unrelated female, would likely bring comment and whispers; both at once would, at best, make one a subject of ridicule. As a result, takmin lesbians generally have poorer quality of life, since they are usually unable to live openly except in extreme isolation, and keeping their orientation secret - or at least plausibly deniable - often involves considerable effort in misdirection, to the point of bearing children for the sole purpose of avoiding suspicion.
Bisexuals have the flexibility to submerge themselves in the general population, though whether they can do so with the one or ones they love is a different question.
There is sometimes room for an individual to take on a socially accepted role as a gender other than that corresponding to their biological sex. In these cultures, a lesbian may be able to classify herself as male, allowing her to marry and cohabit with a “public” female. (In takmin societies, this tends to link the understanding of sexual orientation to that of gender identity, even though they are otherwise separate phenomena.) One of the most prominent takma societies to allow this, and generally one of the most liberal in terms of restricting any behavior, is the city-state of Ǣdyihòzh, which for this reason among many, many others is considered a moral cesspool by its neighbors.
