Final answer:
A symbolic-interactionist would be interested in studying how individuals attach meaning to sexual activity and how this influences their sexual behaviors, focusing on the interpretation of symbolic norms like masculinity, femininity, and heterosexuality.
Step-by-step explanation:
A symbolic-interactionist interested in sexuality would likely examine how the meanings individuals attach to sexual activity influence their behaviors. This perspective centers on the micro-level of social interaction and how individuals interpret symbols and meanings within different contexts. For example, they may consider how femininity or masculinity influences sexual behavior or how societal labels have historically affected the perception of different sexual orientations, such as with the previous APA classification of homosexuality as a disorder.
Interactionists might also be intrigued by the varied interpretations and meanings of sexual behaviors across cultures and individual experiences, such as how the symbolic norm of heterosexuality is established and maintained. Moreover, the study of language and symbolic slurs used to describe homosexuals could be another area of interest since symbolic interactionism looks at language as a core element that conveys meanings.
