Be wary of constant direct clitoral contact.
The clitoris is packed with nerves and super sensitive, so your partner may not want you to touch her there directly.
The clitoris actually extends several inches under the skin on either side of her vagina — like a wishbone — which means you can massage it without applying direct pressure. Trace the extensions with flat, wide, extra-wet tongue strokes, or slow finger zigzags (don't forget lube). Then rub a slow spiral around the top, drawing closer with each pass. The combination of anticipation and indirect contact will bring her pleasure centers to life.
