If there were a quiz that would tell you whether you were asexual, would you take it?
There is, of course such a quiz, created and validated by researcher Morag Yule in 2015. It is said to capture 93% of self-identified asexuals. (As for what it does with gray/demis, who knows?) However, I refuse to take it, or even scrutinize it too closely. I consider it lucky that it hasn’t been disseminated widely. I just think no good could possibly come from it–outside of research, of course.
