HOWEVER,
if the government's
technical paper is accurately based on previous court cases, then lap dancing is a sexual service as well as masturbation at a spa.

The following activities have been found to constitute a sexual service or an act of prostitution,
if provided in return for some form of consideration: lap-dancing, which involves sitting in the client’s lap and simulating sexual intercourse;[31] masturbation of a client in the context of a massage parlour, whether or not the client climaxes;[32] and, sado-masochistic activities, provided that the acts can be considered to be sexually stimulating/gratifying.[33] However, jurisprudence is clear that neither acts related to the production of pornography,[34] nor stripping[35] meet the test. In most cases, physical contact, or sexual interaction, between the person providing the service and the person receiving it is required; however,
acts for which consideration is provided that take place in a private room in a club and that are sexual in nature, but do not involve physical contact between the “client” and “performer”, such as self-masturbation, have been found to constitute prostitution.[36]
