I have no problem with sex work and have no problem with the legalization and regulation thereof.
To me, the is a difference. In the media I've reviewed, there seems to be a checklist of requirements, whether spoke or unspoken: youth, beauty, immediate availability, submissiveness.
Sex worker are all shapes, sizes, ages, etc. I have friends who are former sex workers who found it empowering to express themselves sexually. Not all sex workers enjoy their profession.
A sexual act as a transaction connects value to an act not a person.
