Part of the beauty of a kiss is in it's sybolism. I pity those who have worn out the kiss by devaluing it countless times. Because you can really only kiss a person once. And that kiss is more than the touching of lips, it is more than the beginning of whatever erotic sensations lie below. That one kiss is your acceptance of the other as someone. As Iris Murdoch once it "is the extremely difficult realization that something other than oneself is real." In fairy tales and mythology, the kiss is what wakes up or brings to life. I don't think that a kiss has to mean anything other than, "I see you." Which is, in itself, a powerful compliment. Every time you kiss that person after the first time it is the same kiss, the same statement, the same admission. Every so often, people need to be have that affirmation that they are real.
