you sound naive and must live in the u.s. where escorts are forced to advertise ambiguously due to laws restricting what consenting adults do together, in many countries the escort's ads spell out every service that is offered
also, a slightly off topic word of advice, when you get your "known facts", you should try to stick to scientific journals (and even take those with a hint of skepticism) and not from "magazines" (not necessarily on this issue, but you make yourself look foolish on any topic if you cite your references as "magazines" with such definitiveness)
