Three surprises in the first hour
The first surprise is weight. People expect hands and receive a forearm, a shoulder, the length of a body leaning slowly along the back, and the pressure feels broader and heavier than any massage they have had, yet never sharp. The second is temperature. The gel arrives a little above body heat, and for the first seconds the skin cannot decide whether it is warm or wet; then it settles on warm and stays there. The third surprise is the absence of stops. Ordinary massage is built from strokes that begin and stop, and the body learns to brace for each break. In gel there are no breaks to brace for, so the small tension that usually hums in the background has nothing to attach itself to and slowly goes quiet. Most first timers notice this third surprise only afterwards, when they realise how little they were thinking.
