Strban attitudes towards sexuality

The Kingdom of Strba is unique for its wide prevalence of sororal and semi-sororal polygamy: it is common for a man to marry twins, or women who are sisters. It is also expected that when multiple get married and practice polygamy, all of the involved people love each other like lovers - unless they are siblings. This means that essentially, women are expected to be bisexual if multiple women marry the same man. Men are expected to be bisexual if multiple men marry the same woman - polandry also exists in Strba, but only socially acceptable for women of high status.

Heterosexuality and bisexuality are seen as the norm - being exclusively homosexual is seen as an illness: homosexual relationships are not seen as legitemate or as "true love". They are seen either as just playing around, or as practicing for a "real" (heterosexual) relationship. To escape this, it is common for two lesbian women to seek out a weak man and get married to him, so that their relationship becomes legitemate - unrelated women who get married to the same man are expected to love each other as lovers instead of arguing who is the first wife. This loophole is very convenient for them, even though it's expected for women to treat their husband as the number one priority - likewise, for men in polandry, it is expected from them to prioritize their wife first.

In addition to polygamy, historically, concubinage used to be common before the Ten Heavenly Principles gained foothold. As the religion teaches that people should be loyal to their spouses, the idea that people in a polygamous relationship should love each other as either lovers or siblings. Not even this new religion could root out polygamy in the kingdom of Strba. Not even Shár influence could do it.
