The formulation of the upcoming Sexuality Spectrum mimics the formulation of the Mind Spectrum. That is, how there are only two types of aroused genitalia to have sex with vs. two halves of the brain to think with. For the latter, the distinct characteristic combinations underlying the Mind Spectrum’s Thought Process Foundation are either “all” empathy and little logic; balanced empathy and logic; little empathy and “all” logic; or little empathy or logic.
For the former, the technically chromosome-based characteristics discussed so far helps create the Sexuality Spectrum’s “Sex Partner Foundation.” That is, humans who have: just aroused penis sex making them an XY-sexual; either aroused genitalia sex making them an X-plus-sexual; just aroused vagina sex making them an XX-sexual; or no aroused genitalia sex at all, making them an N/A-sexual, as in not available for having sex.
As a strict reminder, these new terms are designed to fill the gap in categorizing and then labeling adult humans based on which aroused genitalia they prefer to have sex with, regardless of what they identify as. Even better, the newly defined categories and upcoming labels necessarily respect any modern-day concerns about pronoun usage by not using any.
Setting up for getting to the “Front-end Why’s” for gender employment and annual income differences, the Sexuality Spectrum Science then applies the labels of “Chasee” towards the left, “Chasesque” in the middle, and “Chasor” towards the right. The Chasee prefers to be chased by a Chasor leading up to the first consensual sexual encounter; the Chasor prefers and often has no choice but to chase the Chasee leading up to the first consensual sexual encounter; while the Chasesque can be comfortable in either role. The label “Chaseless” is then used for those who do not or no longer have sex. This leads to the completed Sexuality Spectrum as depicted below:
