In a study published in 1979 in volume five of "Advances in the Study of Affect", as well as in another article using the same data and published in 1980 in the "Journal of Personality and Social Psychology", Michael D. Storms of the University of Kansas outlined his own reimagining of the Kinsey scale. Whereas Kinsey measured sexual orientation based on a combination of actual sexual behavior and fantasizing and eroticism, Storms used only fantasizing and eroticism. Storms, however, placed hetero-eroticism and homo-eroticism on separate axes rather than at two ends of a single scale; this allows for a distinction between bisexuality (exhibiting both hetero- and homo-eroticism in degrees comparable to hetero- or homosexuals, respectively) and asexuality (exhibiting a level of homo-eroticism comparable to a heterosexual and a level of hetero-eroticism comparable to a homosexual, namely, little to none). This type of scale accounted for asexuality for the first time. Storms conjectured that many researchers following Kinsey's model could be mis-categorizing asexual subjects as bisexual, because both were simply defined by a lack of preference for gender in sexual partners.
