Vernon - The short answer is most everybody gets it and for many, the immune system clears it on its own. Specifically re kissing:
<<Oral HPV is not casually transmitted by sharing drinks or simple kissing on the lips. It is unknown if penetrating type kissing (French kissing) is capable of transferring an infection.
HPV is not transferred by intimate objects such as sharing a spoon or on surfaces such as doorknobs.>>
The above quote is found at the HPV link noted in your post above and if you go to the link about patients' questions re HPV, there is a wealth of information and all types of questions answered. I have had no direct experience with HPV but you will probably hear forms others who have. Meanwhile - I think you should keep kissing your wife - especially if you are good at it.
