Can you get busted for only offering body rubs with no happy ending? If you do not advertise for massage but only for body rubs and offer no happy ending if you get an LE can you get busted? What if you just give the rub and you stay in your clothes?
... you CAN get busted, not for prostitution, but for offering or performing an unlicensed massage. In some areas, this offense is actually more serious than prostitution. I do not believe that ANY jurisdiction would recognize a distinction between "massage" and "body rubs."
... you're asking about the LEGALITY of private lap dances! The quick and correct answer is that EVERY city and county has its own rules. Worse yet, there are informal enforcement policies WITHIN those rules. For example, there may be a "no touching" rule which the cops actually enforce only when the guys start touching the girls' breasts or waistline areas. These informal policies are subject to change on short or no notice. Club owners and dancers have to keep up.
