The State Transition Structure of Sexual Functioning: Activation, Alignment, and Completion

This study critiques the limitations of existing approaches that understand sexual desire as a fixed trait or a singular instinctive intensity, and redefines it as a state-dependent operational structure. Existing sexual research has primarily explained individual differences through output indicators such as sexual behavior, frequency, and spontaneity. However, such approaches fail to sufficiently account for the phenomenon in which the same individual exhibits different levels of sexual activation, alignment, and completion depending on conditions. Accordingly, this study conceptualizes sexual desire as a combined structure of baseline drive and conditional activation, and analyzes sexual experience as a multi-stage state transition system consisting of activation–alignment–completion. In particular, sexual activation is defined not as a simple stimulus response, but as a selectively opened process conditioned by internal states composed of physical, emotional, and cognitive factors, as well as alignment conditions composed of relational trust, safety, and reciprocity. Furthermore, even after activation, if transition conditions through the Integrity Layer are not satisfied, execution and completion may be delayed, distorted, or collapse. This study reconstructs individual differences in sexual experience not as differences in drive intensity, but as structural differences in activation thresholds, alignment requirements, and execution transition permission conditions. Through this, it proposes that sexuality should be understood not as a simple behavior or output, but as a state transition system that is conditionally opened, regulated, and branched. Such reconstruction shifts the concept of sexual desire from a static attribute to a dynamic operational structure, while maintaining theoretical coherence with the existing MOA–IOA–Integrity Layer framework. Furthermore, by connecting sexual functioning to the general structure of human operation, this study presents the possibility of positioning the sexual domain not as an isolated phenomenon, but as a special case within an integrated operational system, with potential expansion as a middle-range theory.
