Thanks for that thread, Squeaky. Any woman who has ever been homeless or precariously housed will find that very recognisable.
Girls are groomed from birth to be decorative, sexually available entertainment for men. We're taught our power rests in our bodies, so long as they are judged attractive and desirable. We are raised to believe that 'selling ourselves' is a valid and healthy choice. A performer, a model, a bride. All suggest to girls that a desirable life path is to sell their body, their image, their sexual availability. To be a passive object men can project onto, and/or use.
These are common 'dreams' sold to little girls and spun on across all the media. Beauty pageants, swimsuit competitions, fashion spreads, cheerleaders, porn, strippers, etc. Servicing the male gaze/male desire is a huge industry. Porn culture is pervasive. We absorb the message that our sexual desirability is equivalent to our worth very, very deeply.
If one considers society as set up with males holding much of the power (economic, political, physical), and virtually all girls encouraged to fit into that unequal power structure by ensuring they be attractive, available, and for sale, then I'm not really sure whether meaningful consent is really possible.
In an unequal relationship - teacher/student, boss/employee, etc, we don't consider that it's possible. I cannot see how a male punter/woman dynamic is any less unequal. The sex act (or lack of) seems almost irrelevant - it's the power dynamic that is crucial, and that is uneven. I'd say it's degrading, risky, dangerous, frightening, for any woman to have 'sold herself' to a man. Always.
