To penetrate is to get inside, to enter. Penetration is the act of getting inside. For example, "Our house is poorly insulated; cold air penetrates from the outside."

Shallow penetration refers to a position during sex where the man does goes inside, but not as deep. There are a variety of positions when this can be achieved.
