Nah they are adult entertainers not prostitute :P
Although to be sure they are quite close in meaning in that they do get sex for money. But adult entertainers hold themselves above prostitution. They wont do it unless its lucrative and theres a camera and they are looking there flat out best. They regularly use safe sex practices and are regularly tested. They play to the camera, they do reverse cowboys, they have awards and conferences, they take acting classes.
