Kyon does seem to let the man upstairs make the decisions for him instead of the man downstairs.
But at the the end of the day can't it just boil down to him not really being attracted to girls who are anything but "normal"? I mean as fascinating as the three ladies are, they all represent too much of a challenge if you wanted to date them. A deity, a time-traveller and an artificial life form are not exactly an easy proposition, specially for someone as demanding as Kyon.
