immunity kissing

Oooo sooo sexy.

“Kissing transmits germs from man to woman. After about six months of kissing she becomes immune to the bad stuff in the man’s body. By the time the baby is born, it is immune to the things the parents are immune to. Sperm just don’t cut it when it comes to transmitting immunity.”

If unkissers’ offspring did not more often die away would we all be unkissed?
