Absolutely, Positively Not by David LaRochelle (teen book)

Thanks to my librarian pal Beth L. for recommending this funny, charming book to me! Sixteen-year-old Steven is worried that he might be gay, so he does all sorts of things to prove to himself that he's not (learning how to belch, trying to buy a Playboy, etc). Still, he finally ends up at the conclusion that yep, he's gay. This is one of those refreshing teen books that isn't filled with black depression and angst. Yes, there's angst, but the author (writing in Steven's first-person voice) does a great job of infusing Steven's situation and outlook with humor and wit. What a great read! I stayed up too late reading it, always a good sign.
