To explain a bit further, one of those women might be a lot older than the other - or one might have a learning difficulty, or be an employee of the other. There can still be a power imbalance in other words.
And therefore, because such a power imbalance is always possible then any sexual exchange that takes place outside an immediate, empathetic, relational context (and the production and exchange of such imagery is definable as such because the two parties are not present to each other) can lead to commodification, abuse and degradation.
So, what I am saying is that all porn - whether that's 'barely legal slut gets abused' or the two women sexting is wrong. Not only is feminist porn an oxymoron, but no reduction of a human being to abstracted sexual imagery can be anything other than detrimental to sexual culture.
Do you agree or not?
