Re: You mean a woman's orgasms are tied to his genes and income?
An orgasm lets sperm pass the cervix much more easily. Otherwise, the cervix acts as a filter/barrier (cervical mucus) to limit sperm passage. So, traits that make a man seem more desirable as a father, will increase the chances of a woman having an orgasm, improving the chances his sperm will reach an egg. This is true even if she mated with someone else quite recently, but did not orgasm - that guy's sperm are stuck trying to pass through the mucus, while the later guy's sperm take the expressway. Symmetry is one indicator of good genes, as are good overall health, good skin tone, clear eyes, etc. What makes for a good provider has changed over the millennia, but the important thing is how well the man can support his mate and offspring so the children survive and thrive. Consensus of peers affirms a woman's perceptions that a man is a good mate (whether or not he actually is).
Love is an ideal thing; marriage is a real thing; a confusion of the real with the ideal never goes unpunished. - Johann Wolfgang von Goethe
