My partner and I have a rather large problem: we have, quite possibly, the most BLAND rumba anyone has ever seen. Our coach refers to it as a "textbook rumba" - basically a collection of predictable, plainly executed steps that is about as fun to watch as paint drying. She wants us to try to interact more on the floor and be "more sensual" with one another. The problem is that I don't know how! Any hints on how to "sexify" our routine?
