Well, why are you going to get one if you are going to cry. Right before the massage, just tell the person who is offering it to be gentle and that you have sensitive skin or something. Tell them that you were about to cry last time and that you want it more smooth. If you didn't like the other massage-person, go to another one. Be sure not to tell them something like, "I have scoliosis, so be careful," because they'll try to pop your spine back into place.
Good luck and I hope this is helpful!
