I spent a lot of thing thinking over the plots of my stories, and since most of my stories centre around "platonic" relationships that are actually secretly yaoi relationships, I think about it quite a bit.
And of course most of them time I'm on the computer I'm chatting with a friend about my slash, or have a fanfic or some manga open in another tab for some light reading, so... it adds up. xD

I think the worst part for me is when I'm trying to do something serious, like read 1984, and I'm just like "Okay, so Winston is tied down and... WAIT, I CAN'T THINK THAT!!!"
You can't? ninja
Didn't stop me.
