Final answer:
Sexuality is mainly considered cultural, being shaped by societal norms and values. Sexual orientation is categorized and viewed within cultural contexts, and what is considered 'normal' sexual behavior varies widely across cultures. Sociocultural influences greatly impact one's perception and expression of sexuality.
Step-by-step explanation:
According to the texts, most of sexuality is cultural. Sexuality, involving a complex of thoughts, desires, and behaviors, is largely shaped by the cultural norms and social constructs prevalent in a given society. While biological aspects are certainly present, the overriding influence seems to be the sociocultural environment that molds individuals' perceptions and expressions of their sexuality.
Sexual orientation, for instance, is categorized within cultural constructs, with societies having different norms for what is considered acceptable sexual behavior. Factors like family, education, peers, media, and religion play pivotal roles in one's sexual socialization. This influence is reflected in varying national attitudes towards activities such as premarital sex, and the acceptance of different sexual orientations like homosexuality, bisexuality, and asexuality.
Thus, a person's sexuality is not only a biological aspect but also a sociocultural identity. Cultural norms dictate what is considered 'normal' behavior, and these norms can vary greatly across the world, from conservative to liberal stances on sexuality.
