Am I concerned about the sexualization of women and girls? About rape culture? About trafficking of women against their will in the US and internationally? Absolutely. But none of those battles are won by criminalizing the sale of consensual sexual services between adults.
It has become kind of OK to say you did a little sex work -- if you put it down to fun, or research, or empowerment. If you did sex work strictly for the money, you can only really admit it if you put it in the past.
