In Proverbs 5 wisdom advises man to enjoy the sexual encounters with his own wife instead of another woman (5:18-19). The fountain image of a woman is also found in Song of Solomon 4:12 and 4:15.
A man’s “wife of your youth” is illustrated as a doe or a graceful deer. This illustration is also similar to Song of Solomon (the man is "like a gazelle or a young stag" in Song of Solomon 2:9; 2:17; 8:14.)
The desire of godly wisdom is for a man to be intoxicated physically by his wife’s breasts and emotionally inebriated by her love.
The Bible clearly explains the chaos and disaster illicit sex produces in mankind, but promises a lifetime of sexual joy and refreshment to a man and his wife.
The springs and streams of water seem to refer to the man’s sexual desires and encounters. Likewise, the cistern is a reference to the man’s wife. The waters from the man’s spring do not belong in the street. Instead, a spring and its spring water are used for refreshing and for refilling a cistern.
A wife’s love will make her husband stagger as if he is intoxicated (5:19), but the husband is told that another woman should never make him intoxicated (5:20). If he does become intoxicated with another woman the man will be led to his destruction (5:23).
