I hear you. A society not heavily based on the family unit is dysfunctional to my understanding and observation, and I may well be overlooking my own advantages. Still though, at base, I do not believe that it is any sort of difficult thing, this relating to the the opposite gender thing of which you speak -- you just find the one with whom you build your family and get to know each other. The others you treat professionally, without reference to their sexuality.
I respect but cannot speak to your personal experience, not because I don't believe that a valid means of securing knowledge about the world, for indeed, I hold it to the basic, but because I simply don't know enough about the experience and the context to make any sort of judgement.
Thank you, though, for responding.
