Goku didn't know what a kiss was even when he was an adult. So Chi Chi would have to figure out ways to get some extra affection in her loveless marriage.

@ssj782: To be fair, Goku not knowing what a kiss is, is only possible if Chi Chi never taught him. And if she was too busy munching elsewhere I can't really blame her.
