Sex without love is a meaningless experience but as far as meaningless experiences go its pretty damn good.

To love is to suffer. To avoid suffering one must not love. But then one suffers from not loving. Therefore to love is to suffer not to love is to suffer to suffer is to suffer. To be happy is to love. To be happy then is to suffer but suffering makes one unhappy. Therefore to be happy one must love or love to suffer or suffer from too much happiness.
