Nostalgia.

Christopher Isherwood is in the news thanks to a play about him on BBC.  Back in my childhood - I suppose I'm talking about when I'd be about 13 or 14 - we had a bookcase in the hall, full of my parents' books, which I'd dip into when they weren't about.  One was called "I Am A Camera" and it was written by or about Isherwood and his experiences in Germany just before the Second World War, and it opened this young lad's eyes to a world so very very different from the one I was being brought up in.  I don't remember noticing any particular homosexual content - but then I went to an all-boys school, so the idea of men hanging out with other men wouldn't have struck me as strange.  I do remember having the hots for Sally Bowles though!
