ABCD types
Two common cross-classifications within the spectrum of asexuality are based on romantic attraction (some asexuals desire romance with one or more genders, and some don't) and sex drive (some asexuals experience sexual arousal, but without the desire to express it with another person). One way of classifying asexuals is to sort them into the following four basic types:
Type A asexuals, who experience sex drive, but no attraction;
Type B asexuals, who experience romantic or other forms of attraction but do not have sex drives;
Type C asexuals, who experience sex drive and romantic or other forms of attraction, but do not see them as linked;
Type D asexuals, who experience neither.
This classification system was retired, because not all asexuals felt comfortable putting themselves in one of the four categories. However, some asexuals still find it useful to reference the concepts of type A, B, C, or D at times. [1]
Recently there has been a resurgence in the use of type ABCD classification [2]. Without the existence of such categories pointing out obvious differences, it can become easy to lose sight of the great diversity of that asexuals experience. In particular, it can become easy to assume incorrectly that all asexuals are type D. [3]
