I was looking at Viera lore and it got me thinking. Wouldn't homosexuality be considered the norm with Heterosexuality being the very rare exception with their culture the way it is in regards to male and female interactions.

According to the lore, the males are never present except in the case of mating and picking up the young males and taking them away. The way it is described gives the sense that this practice is very dissociative with each other and the practice of mating unlike most other races is done as more of a duty to their tribe than an act of love. However we also know female Viera are not loveless beings. So isn't it possible that Viera women are more likely to develop romantic relationships with each other than they would males, with males develop relationships with other males to a lesser degree since males are solitary creatures by nature.
