The erotic adult work is a job, that only a 18+ person can do, because it includes sexual services and in return, the client pays money or buy expensive gifts. The sexworker's service can include almost anything, even adult job without sex eg. fetish jobs, femdom, massage job, hostess job, webcam job or dancing, but the choice is always yours, nobody can force you to do sexwork. Usually we distinguish between incall and outcall erotic jobs, so the sexworker can work in a studio, private salon or brothel, or it can be outcall, so they meet somewhere with the guest, that can be a hotel, the client's house or anywhere else.. And also it doesn't matter if you are boy or girl or trans or even your sexual orientation, because any adult person can be an escort or a sexworker.
