Hormonal birthcontrol. On their cycle, a woman's preferences change. She wants to be around masculine smells that carry the scent marks for a different immune system dna. When not on her cycle, a woman wants to be around familiar smells, like family.
So, when modern couples try to start a family, the woman's body realizes he smells like her brother/father and she is subconsiously repulsed.
Male circumcision: Ever wonder where that "ridged for her pleasure" style of condoms came from? It emulates the folding back of skin on an intact penis. The rise of circumcision resulted in less pleasure from intercourse for both parties.
It also caused a rise of premature ejaculation.
Female masturbation: With the destimatization of this act, women started abusing themselves to the point of nerve-death from overstimulation.
The Sexual Revolution: With the destimatization of infidelity, premarital sex, and all those other little taboos, women became aware that while they're young and pretty, they could land nearly any man for intercourse. They think this continues their entire life, until the wall arrives and teaches them otherwise.
The number of life-time sexual partners also decreases to ability for a woman to subconsciously feel like a relationship is a permanent thing, worth investing in.
And so, we arrive at the modern condition. Literally everything is stacked against the possibility of forming a functional pair bond.
