Is massage with oil considered prostitution? Can massage with oil be punished as prostitution? The legal characterization of massage with oil

Rubbing oil is originally a healthy and legal activity. It is a way of using skin care oil to protect dry skin. However, "rubbing oil" in entertainment venues often involves a masseuse applying oil all over the customer's body and then massaging and rubbing oil on the customer's (male) genitals, which usually leads to male... arousal or sexual stimulation. This kind of service has crossed the boundary of legitimate health care and may involve illegal activities.
