You have to wonder why there isn't a word in the English language for the fireworks that go off in your brain when you finally kiss someone you've wanted for years. Or for the intimacy and tenderness you feel as you hold the hand of a suffering friend. A generation after the height of the AIDS crisis, what is it like to be a young gay man in New York?
