I'm reading Times Square Red Time Square Blue by Samuel R. Delany. I'm not a science fiction fan, but years ago I read his memoir The Motion of Light in Water, which is about his life as a young writer living on the Lower East Side in the late sixties, when he was married to the poet Marilyn Hacker. It was one of those life-changing books.
This book I'm reading now is about the Times Square porn theaters, from the seventies through the nineties. I don't know of anyone who writes so humanely, and so sanely, about anonymous public sex. Anyone who doesn't understand why some people seek it, enjoy it, even consider it important, should read this book.
