Anybody who read books during adolescence that they shouldn't have?

I enjoyed "The Collector" by John Fowles, and "Lolita". "Tropic of Cancer" and "Capricorn" were so-so but too lonely and old mannish. Didn't like D.H. Lawrence but my girlfriend did. There's one I'd better not mention here. In my early adolescence I was obsessed by a novel about young, unrequited love which I can't for the life of me remember the title of; there were traces of Great Expectations but it was by a woman and slightly more risque. When I was a first-year student in London my landlady, not much older than myself, enjoyed discussing such things with me. It meant plenty of free drinks, useful for a student. She couldn't understand how such things could be available in Holy Ireland. The English blind spot about Northern Ireland !
