How do you define attraction?

Who do you find attractive. What qualities make them attractive to you? Why is it that this person is attractive to you? Love, lust, sex, boundaries these are things that we struggle with today. How we define male and female and what relationships are appropriate has been an issue since mankind's origins. It is clear that men and women are different, but why are we that way and why do men try so hard to be the dominant of the two? Different doesn't mean one is superior, it just means that we have different expertise to bring to the table and together we can accomplish more then we ever could on our own. Male and Female are but two parts of what makes up humanity. At our core we are exactly the same. Men have certain qualities that make them naturally better at certain things and women are naturally better at things too. There is so much more to explaining this then genetalia. For starters, why is the jobs men typically do more important? How we define worth in our society really confuses me. I have been at the very bottom of a company and at the top of a company. Truth be told I find more worth in the individuals that do the lowest paid jobs then the ones that get paid the most. There are two ways to look at this. Science or Religion. I find many religions confusing. Parts of their scriptures teach equality, but a lot of what is preached and done is far from equality. Marriage is diacussed but its not typically about love its about male ownership of the female. Homosexuality is eather barely discussed or only male homosexuality is discussed which brings up a double standard for lesbians. Science has come a long way in helping us understand ourselves, but I have not seen anything that discusses the how or why we are atracted to certain individuals. Without fully understanding the why how can we tell people they are 'loving wrong.'
