Lean in closely to your partner and look into their eyes. If they want to be kissed, kiss them. Tilt your head slightly to the side so that your noses do not bump. Keep eye contact with them until your lips touch, at which point you should close your eyes. It is generally considered rude to kiss with your eyes open and can ruin the intimacy of the moment.
Let your lips softly touch and pull away from each other in a kiss. Pause for a moment and gage how the other person is enjoying this kiss. You can pull away slightly to look into their eyes. If they liked your kiss, try another one on them. Maybe let this one last a moment longer or kiss them a couple times. Make sure your kisses are soft.
