You can do the same thing that a massage therapist can do when they feel uncomfortable; tell them that they can stop the massage right then and now. It goes with both ways and not so much for man massage therapists but for a woman massage therapist. Sometimes man will go in for massage thinking that there should be more than just a massage and they are making the massage therapist uncomfortable. Some massage therapists will give them a warning and sometimes they won't. Sometimes they say "I am sorry this massage is over, obviously you are here for other things." And in the same way if you are a client and you feel uncomfortable with the woman or man or if things are being done that shouldn't be done you could say "I don't appreciate this type of massage and I want you to stop right now," and get dressed. But I tell you that as far as the client feeling uncomfortable and it hardly would ever happen. When someone is going to get a license as a massage therapist, they are usually proud of their work or what they do. I would say that if you find this happening in one out of 20,000 massagers that would be a lot. I am not thinking it never happens, I am just saying this does not happen often.
