As couples become comfortable with each other, kisses can become lame. Get rid of the pecks and get serious with the kisses. The next time the two of you greet each other, enjoy your kiss and do not be so quick to stop. While there are appropriate times for serious kissing, they should be loving, sincere, and passionate, regardless of how long they last. You will find that as you pay attention to your kissing and let your mate know that you enjoy kissing them, you will both feel better about your relationship.
