I'm not sure it's just the case that men desire women more than women desire men. I think it's more to do with the narrow mindedness of society. For example, only certain men are attractive to girls, and those girls worship their asses as much as men worship theirs. I think this is especially true in the UK where their is a very potent and clear 'status culture'. Girls here are less open minded and only chase one type of guy (tall, white, middle class?) dictated to them by the media. So anyone who doesn't fit that stereotype will have a hard time. Society has become so narrow.
Sadly in this country there is only cool and desirable or uncool and undesirable and people judge in a split second which category men fit into.
