I extend Dawkins' Battle of the Sexes by introducing a population with mating structure. Previous models of the battle of the sexes specify a dynamic system on the basis of the payoff matrices of the evolutionary population-game. Here the sex war is modeled by expressing the costs of raising offspring and performing a prolonged courtship in terms of a time delay during which individuals cannot mate anew. The dynamics of this model are qualitatively different from those of the `homogeneous' models of the battle of the sexes. Evolutionary predictions of a game-theoretical model, in which the costs and benefits of a strategy are summarized by a single entry in a payoff matrix, may be quite different from a model that explicitly considers the mechanisms controlling mating in a structured population.
