After fucking the same man for a while and not getting pregnant, the foid's instincts start subconsciously telling her that the man is infertile and then drive her to lose interest and seek out a new mate.
seems like a logical theory to me
condoms also stop the transmission of neurochemicals through precum that help pair bonding
without pair bonding chemistry they are more likely to lose interest
If you at least precum in her pussy then pull out and cum on her face / in her ass / in her mouth it might work better than a condom catching it all
but I still agree with you that impregnating her is the most important thing to convince her subconscious of your virility
that said: let's not act like this is a guarantee or anything. You could impregnate a woman constantly for 5 years and you could still get cheated on the instant chad walks by and mogs you
This is at best one of many factors that might tip scales in edge cases.
Perhaps another factor is also that impregnating the women makes them less appealing to other men (they get stretched out, fat, more masculine, carry a burden) so the women have reduced sexual opportunities from appealing men.
Not caring for children would also leave more free time and boredom to cheat. Plus no sense of obligation to stay with you for sake of child during rough times.
No, the opposite really.
Lower IQ people are the ones that are most likely to not use birth control right now.
If we forced everyone to stop using it, the lowest quality people might start breeding more,
but the highest quality people would start breeding a LOT more.
IQ relationship to birth control is probably a lot like it is to racism.
