So, to use a hypothetical example:
A man fucks a woman who is very drunk, so drunk that she's just lying there. The woman, the next day, makes a complaint that the man raped her (which, of course, is exactly what he did) In the current, widespread, commodity view of sex, the man could say, 'well, she didn't object, she didn't say no' and some people would go, oh that's all right then.
If the performance view of sex was more widespread, the police interview would go along the lines of, 'hang on, did she put her arms round you, did she say 'Oh yes darling that;'s wonderful? No? What did she do?'
And the man says, well, nothing, but she didn't say no.
ANd the interviewer would say, but she wasn't participating, wasn't showing signs of enjoyment, why didb't you ask her if she was having a good time?'
