Onee-Sama=Older Sister, used as a deferential term of respect for a female authority figure. Which usually is the dominant one in the Yuri animes. Yuri=Girl Love
My record as a Geek Chic is fairly established, and that includes anime, and what got me into anime was learning that the Japanese were so open to girl love they had a full blown category for it.
Janine, I don't see anything wrong with beeing abit geeky and liking stuff. The Japanese where very perverse in their history, then they where industrialized and started to adapt western standards. Now they are getting more perverse again, with the idea that things are forbidden which just makes it even worse.
I've got a girlfriend that is a real sucker for yaoi (boys love), she just loves the forbidden love idea about it… and seeing two hot guy together. I think she wouldn't like to see another girl take the character she likes.
