Well, I'm probably biased, but the Klein Grid looks to me like the pinnacle of sexual privilege. Seriously, not even the "sexual behavior" questions merit a "no one" option? (I'd add it to all the questions, but assuming people need to have had sex on the last 12 months to figure out their sexual orientation seems crazy to me). I can't fill that thing without lying on half of my answers, and I don't even identify as asexual! I go with queer or "bi", my sexuality is fluid across the Kinsey spectrum and the sexual-asexual spectrum.
