• Kissing is an intimate act that involves touching, caressing, and exploring each other's bodies. Start by kissing lightly, then gradually increase the intensity to build up sexual tension.

• Use your hands to touch his body, hair, or face while you kiss. Gentle touches and massages on sensitive areas such as the neck, ears, and chest can bestimulating.

• Use your mouth and tongue to explore his lips and tongue. Try different kissing techniques such as biting, sucking, and nibbling to create more excitement and arousal.

• Whisper sweet or naughty things in his ear to turn him on. Compliment his appearance, tell him how much you desire him, or share your fantasies with him.

• Set the mood with appropriate lighting, music or scents. Create a romantic or sensual atmosphere to help him relax and feel more comfortable.
