What guys primarily want: Hot bodies
What women primarily want: Money
Who do you think has the hot bodies and who do you think has the money?
The more financially secure a woman is, the more superficial she becomes, i.e. attracted to a man's body. The less independent she is, the more she looks for a dad to take care of her.
Men don't do that, cause they can't. You can't rely on the "sugar momma" plan by dating cougars unless you're like Brad Pit hot, whereas a girl can fall back on that plan as long as her BMI is 20 and she has some teeth left, as long as she's willing to date a balding 40 year old accountant with anger issues.
