That whole switch-up thing is so damn weird, and kind of scary at times. I'm right in the middle of that currently, I thought I was attracted to only girls for a while, admitted to being bi, and recently realized that my interest/attraction to girls has been decreasing and then more or less just poofed entirely. I can still appreciate a girl's attractiveness, but there's zero sex drive there. It's so weird.
And DAMNIT those moments are infuriating, aren't they? I was looking for D&D books with my friend Chase and the clerk was effing adorable. I couldn't figure out what books we needed because the guy was too distractingly cute X_X
