Took a massage class once. Instructor mentioned how difficult it is to do anything with a fat person. You can't really access the muscles and the amount of pressure you need to apply will most likely hurt you and they still won't feel it. Like trying to massage someone wrapped in 2 or 3 sleeping bags. I had a boyfriend with some light back acne and I wouldn't touch his back without a shirt on. I can't imagine having to touch a fat person with all those moist sweaty fungal rolls and probably zits and shit. eww.
