This study attempted to identify one aspect of the development of the sexual self - assuming a certain gender. Semi-structured interviews were conducted with four individuals whose sexual selves had fluctuated before becoming localized, and the process of transformation of the sexual self was extracted for each case. The results of the analysis using the verbs "to fit in/not to fit in," "to catch up," and "to overlap," which express location, showed that the sexual self had various ways of being, and emerged with the connection between the body and the environment.
