I've repeatedly referred to fictional manifestations of "sex and violence" as "affects" because that's what they are in an extra-diegetical sense. For the audience of a given narrative, they are narrative events that are meant to generate strong, if purely gestural, emotions in that audience.
WITHIN the narrative, however, these manifestations are not only not "fictional," they are activities that function diegetically as instrumentalities, as per this definition:
a thing that serves as an instrument or means to an end
More on this later, possibly.
