Every female cuckolds the man she is with, the problems arise because females value their "social standing" far more than mate viability. So today women waste their peak fertility chasing unattainable men, get knocked up, then he abandons her if she hasn't driven him away with her feminist bullshit. Then she is stuck as a single mom because no matter how erotic the thought is, males do not want to care for another males offspring. In nature those children are killed by the new male, or they are tossed out on their own and they die. That's REAL NATURE, not the porn fantasy, which all the single mothers who are trying to hook a "cuckold" can attest to. No man wants them because men EVOLVED to avoid that situation, and that is why women always lie about their partner count or who the actual ******* of a baby is, but modern science with paternity testing has taken that option away from women. Before white men created the modern world if a female was shunned by her tribe she would quite literally die because females are not capable of surviving on their own, they still can't, but with modern technology their odds are much higher.
The human female dual mating strategy is the root cause of all of this, her find "best male" then bear his baby and hope "best male" will stick around and bring food back to cave for female and offspring.
the problem is that "best male" who has the best genetics AND can fight off the rival tribe, ******* random dinosaurs for food and has a big cave is almost NEVER the same person so the female seeks two distinct males, one for "genetics" and the other for "survival" and both are cuckolded by her choices.
The "genetics male" gets the baby, but she lies and says it's not his and convinces the "survival male" he is the ******* so that she and the baby don't starve.
