A question based on observation. Why is it that most women who go to sperm banks do so out of desperation when they are nearing 40 apparently unwanted by men or incapable of consumating a comfortable relationship with one in time to have a possibility of a traditional family unit at least for a few years?
Men are needed and this other thing is a cop out and coverup for dysfunction in pairing up.That is probably way too harsh. Maybe it is part fate. Fate just doesn’t serve up the opportunity for some reason? Not that these are not wonderful women in so many ways. I have met several. I have known several over decades and know that they had unfullfilled longings for quality male companionship before they took this ultimate decision. In some instances I might have been “the one” had they been more capable and/or more seductive.
Also in the animal kingom all this offspring rearing and pairing up happens with different degrees of “parental bonding” Some animals, even birds pair for life. They can’t help themselves. Others do so to varying degrees and periods of time. They also can’t help themselves given normal circumstances. Humans are significantly a pairing animal. Nature creates the need. Sure it can be subverted or missed, but that doesn’t mean it is not inherent in humans and if it is not, lack is isolated to individuals.
Maybe epidmeics of this lack are possible in sophisticated civilization but even that hasn’t proved that nature has changed.
