This is not to say that all men will simply flee the scene once they’ve consummated their desire: for starters, we’re a hell of a long way from evolutionary equilibrium, and even then it’s not clear that the game in question has a dominant strategy, especially once you factor in complicating influences from women’s sexual selection of men and from various social pressures. More likely we’d see a diversity of different strategies.
