Oh for fuck's sake. I am a trained scientist and I can distinguish between societal norms and biological urges.

Sexual selection as first outlined by Charles Darwin and which has since then been one of the hypotheses which has garnered more backing through research shows that on average women of reproductive age (that is anything from 13 to 40) prefer older men because an older man demonstrates that he is successful and can care for offspring. A woman has much to lose if she gets pregnant and has no man to help her so women tend to go for men who have demonstrated that they are successful and dependable.

Men, on the other hand, are biologically 'programmed' to mate with females who show signs of good fertility and of good health. There are biological reasons why most men prefer women with the 'Marilyn Monroe body'. The wide hips and ample bosoms are excellent signs of fertility and of being able to raise children.
