So I guess the distinction I'm trying to draw here is if the woman herself doesn't find it objectifying, and if her decision to engage in it isn't influenced by externalities.
We still get a hard-on watching her sex scenes today! No, your mistake is thinking that objectification and empowerment are on this single line, the two are completely different.
Of course by 'problematic' you don't just limit it to the female in question, you have to look at the context as a whole.
