A little self-touching, no matter how subtle, adds interest. Remember, we touch or reach out as if to touch, or touch ourselves when we are around people we find attractive.

Then a little self-touching

Putting it all together we have:
 1. Self-touching
 2. Thigh flashes
 3. Chest thrusts (Leaning Back)
 4. Forward leans
