lol i wonder how many 'yuri' couples in this kinda world are 'legit' versus "well, there's no way i'll ever hook up with a man"
I imagine every girl would be a 'yaoi hater' by default unless they're also uncaring about getting pregnant versus "i wanna see boys happy together after they're done with their duty to provide /keep the population going" Altho it must be a nightmare for actual gay guys in this world or someone trans who wanted to be a girl (tho even if they could somehow get their hands on hrt medicine, i doubt there are enough 'male doctors' [if they're willing] versus like trusting to be sedated by a group/female hospital to get a sex change operation but i doubt it'd ever get that deep into lore diving)
In that world, a guy going for the gay life is a true loss for the human species, considering how rare guys are. Though that being said, it's not a catastrophe since they rely on artificial insemination anyway.
Well, not like they're forced to marry but they're required? to just donate sperm like once a month or whatever it was , tho even if they're not gay, based on how MC's family said that men are treated/react to women i imagine it would be rare for them to actually be attracted to a woman considering some can't seem to contain themselves, tho given the over population of women i wonder if there are female equivalents of 'eunuchs' being made into adult guards or so past high school/college age (Unless til after a while someone elderly ends up 'settling down' with a housewife so they don't have to worry about them being insatiable, or if they're infertile [tho irl i know it's possible for like a 60 year old to knock up a 20 year old])
