I agree with you, RMTs constantly have to fight the stigma of being a "massage worker" and what that means. Part of the way they fight that is by having a line in the sand that they will not cross. They want to be considered health professionals, and rightfully deserve to be considered so.
Having said that, the stigma that they fight against is born from an archaic attitude that sex and anything related to is naughty(or worse). The idea that sex or sexual pleasure for the sake of pleasure alone is normal and healthy, is something that we (as a society) have not publicly declared. To be a sex worker or customer of a sex worker in our society is to participate in a practice that is not socially accepted as "good". I think we all know the value of it, especially here. As long as the activities remain socially taboo they will be relegated to exist in the shadows of polite society. That's a bad thing in my opinion because in those shadows there is a great deal of room for truly unethical people to flourish. Those who would cheat, manipulate, or wish to do another harm, have a much easier time when people are anonymous and things are not openly discussed. So, the taboo that society believes in that "sex is bad" becomes a self-fulfilling prophecy.
So, I agree that an RMT is likely to be insulted if asked to provide a HJ. I also think that RMTs are people and if you get to know someone and can have a discussion about what they think about all of these issues. Maybe, just maybe, in a safe environment free from the concerns of what society thinks and what insurance companies are willing to pay for, those skilled professional hands can be free to see a "full body massage" as just that, no more, no less.
