The people SAYING it are taking it literal, since figuratively we ALL "sell our bodies" every single day.You're taking "selling a body" as a literal sense.
No, they are expected to perform a service agreed upon by both parties beforehand.It's not meant to be literal. You can sell ones body for a night or for an hour or for how long one see's fit. Usually prostitutes do sell their body--not just sex. Prostitutes are usually willing to perform almost any sex act (I know this is not always the case). In some cases they are expected to be extremely submissive while another perosn has their way with them.
They're selling a service, just like everyone else in the fricken world. In the case of prostitutes, it's a sexual service. Being a computer admin can have "grey areas". It's not a product that's black and white. Neither is selling janitorial services. Or computer services. Or housekeeping services, or waitressing services. And, btw, aren't waitresses expected to be submissive while people tell them what they want, demand that they are brought what they want, and then get bitchy if it's not "just right"? Isn't the customer "always right"? Aren't they expected to do whatever they're told to?What is sex exactly? How can one sell sex? Define sex in clear terms so it cannot be misconstued. Is sex only access to the vagina? It is only access to sexual organs? And what would you consider sexual organs since I've noticed a lot of women on here do not think breasts are considered in that catagory? What is the "product" you call sex in black and white? Since really, both terms selling sex, and selling your body both fall into a grey area.
No service is black and white. The terms of service are always agreed upon by the people involved. People agree upon the terms of their employment upon agreeing to take a job. All jobs are different, even in the same field. Prostitution is no different from any other job in any respect.
