Gently arousing:
Massage or stroke gently - a good zone to start with during seduction and foreplay as stimulation is pleasurable, but not as intimate.
The upper limbs respond well to gentle as well as firm pressure. Knead and stroke the fingertips and hands. Then move strokes up the arms towards the shoulders. Firm massage of the shoulder area is great for release of stress and muscle tension. Soft touch and gentle scratching of these areas are intimate and extremely pleasurable.
