When most think about BDSM, they think of static roles: a top who dictates everything and a bottom who does exactly what he’s told. It’s a bit more complex. There’s a subtle difference between being in control and being the one who’s driving the action. Power is like a tennis ball that gets swatted over the net. Sometimes it’s in the top’s court and sometimes it’s in the bottom’s court. The longer the volley between the two, the more exciting the game. Exchanging power back and forth keeps things interesting.
