Is this the very place where Mailer poses the question? Why do gay men tend to gather in cities that boast giant phallic monuments? To be honest, I can't quite recall. It's a rather thought-provoking query. Maybe there's some underlying psychological or cultural factor at play. Do these monuments hold some sort of symbolic significance for them? Or perhaps it's just a coincidence that these cities happen to have both the monuments and a relatively large gay population. It could also be that the visibility and openness of these cities attract gay men from all over, and the presence of the monuments is just an added aspect. Without further research or Mailer's own explanation, it's difficult to determine the exact reason behind this phenomenon.
