Growing up, I was told frequently to not trust strangers. While this advice is problematic for Christians in some areas of their lives (such as evangelism or hospitality), it is vital advice for protecting the intimacy God has reserved exclusively for marriage (Hebrews 13:4). As we study Proverbs 5:14, 21-23, we'll see the author of this text warn his son about the dangers of inviting a stranger into the intimacy that should belong only to his wife.
