Why are women so different from men when it comes to dating and attracting?

Women are naturally attracted to men who exhibit a large capacity for being able to attract women other than themselves. They may not want to act on their innate impulses to find attraction in such a male, but inevitably find it difficult not to do so. Most women are happy to share a perfect alpha male with each other so long as none of them know that they are sharing him with one another (and many times even if they DO know.) This, my friend, is the counter-intuitive behaviour I think you were speaking of. It will forever be.
