Why Men Love Women?

I've been thinking hard why men love women and been mentioning my thoughts to my wife. I'm seeking her response if these ideas were at all plausible or not...

1. It's their intoxicating smell.
   
2. They give you an offspring or two.
   
3. They manage your finances.

The list may go on... but so far that's what I've collected. {31 July 2009}
