There are any number of Yuri manga that I know I'd probably like, but to start them at this point is a little daunting. But last night I picked one of them and started at the beginning: The Boy That She Liked Wasn't a Boy, also known as "Green Yuri", I guess because a lot of the art uses green as a color to enhance black and white art. Anyway, if you think deciding to do this a half hour before bed was a bad idea.... it was. :P
