" We're not meant to separate sex from love; there's a reason why euphoria occurs in both situations. Sex and love nourish each other. You can argue it's humanity's way of establishing family groups and guaranteeing creation of the next generation; but the simple fact remains: the more often two people engage in sex, the more likely it is that one of them will fall in love.
