A massage parlor in my town recently got busted for giving happy endings. After researching the subject I have recently discovered "yoni massages." So what I have found is giving a guy a handjob is considered prostitution but a yoni massage is perfectly legal.

A Yoni massage or yonic massage, derived from the word Yoni, a representation of the vulva which symbolizes the goddess Shati, is a type of tantric full-body erotic massage. It primarily focuses on the labia, clitoris, g-spot, uterus, the breasts, the anus and other erogenous zones. The massage is viewed as therapeutic and is sometimes used as a method of relieving tension, pain, or general discomfort of the vagina. It has been claimed by some practitioners to be helpful to achieve fertilization,  although there is no scientific support for this claim.
