Oversexualised used this way refers as much to an industry/society as individual people. For example, while individual sex workers might have autonomy and we can respect their choices, we can still notice that our culture creates a situation where women are primarily given value for their physical attributes, above others, and that this applies less to men.

Right? And the audacity to claim calling them out is harassment is just uhm … creepy to say the least.
