yes, the man being a mind reader shows a woman how much he cares
Despite the sarcasm, you are actually correct in a sense. This thread inspired me to reread "Sperm Wars" by Robin Baker. The book outlines how our subconscious urges define all aspects of our outward sexuality. Every person is subconsciously wired to try and have as many children/grandchildren as possible, homosexuals included. But beware, you'll never look at a relationship the same again. Infidelity lurks everywhere. 10% of children in the U.S. are unknowingly raised by a man who falsely believes he is the father. 5% are conceived when a woman has more than one man's sperm in her.
A man's goal is pretty straightforward: sleep with as many desirable women as often as possible without acquiring a disease. Despite what Cosmo and Redbook say, there are no secrets to pleasing a man. Most men can't have tons of partners with good genes, so they choose monogamy to try and guarantee the chance of a few children with the subconscious thought that there will be opportunities for infidelity.
Women must behave much differently since they can't have as many children as a man. Women's sexuality has evolved as a method to mask their fertile phases such that they can best deceive men (subconsciously) and influence who fathers their children.
Female orgasm has great influence over fertilization. It's a mechanism that allows her to prevent all her partners the equal opportunity to conceive. Any man who can make a woman orgasm during or immediately after intercourse has a much better chance of fathering her child. She's got to be able to sway the odds if she gets as much as a single chance with a desirable man, infidelity included. That is why all women orgasm in different ways, and you unsatisfied men should make sure your wife tells you how she likes it. Her body knows that any man who knows how to work her individual body type without express directions has likely learned from much experience with many other women. Hence, any son of that man is also likely to be very desirable to women and have the chance to father many grandchildren. However, most women compromise when selecting a partner, opting to choose a man who can pass on good genes but is also likely to help her raise the children.
