Men and Sex

In my futile attempts to understand the sexes, I came up with the following hypothesis: All men desire from women is sex. Yea I know it is cliche but think about it.

Men can provide for themselves materially, and can maintain a home, feed themselves and (hopefully) clean up after themselves.
Men are more stable emotionally, and can subside without a woman to be dependent on.
Men are direct and straightforward, and are more adept to solve problems.

The only thing a man cannot provide for himself is sex.

Blah blah I'm a sexist, and don't really know anything deeper about woman. I am not claiming to be right, just doing a thought experiment.

This just makes me think more about traditional gender roles. There is a good quote "Men can build a house, but only a woman can build a home". There is truth in that, but it still makes me think that sex is the only thing women have to offer, and sadly it becomes a bargaining chip in order to get a man who can provide for them.

It might be just me.
