What does Proverbs 5:5 mean?

The book of Proverbs often warns against following ungodly examples because such acts lead to negative consequences (Proverbs 1:19; 4:14). This is very much true of those who tempt others into adultery. Solomon points out the symbolic seductress's impending judgment, saying her feet go down to death and her steps tread the path to Sheol. In blunt terms, those who tempt others to violate marriage are on a journey leading to hell.

Of course, despite the natural consequences of sin, even an adulteress—or adulterer, as the concepts apply equally to both sexes—can be saved from such a fate if she repents of her sin and trusts in the Lord to save her. The book of Judges identifies a prostitute named Rahab, who turned her back on her sinful lifestyle and put her faith in the God of Israel. Although the rest of the residents of Jericho, her city, perished, she was spared (Joshua 6). No one is so sinful that she or he lies beyond God's power to save.

The fact that Christ saves does not change the importance of this verse. Following the path of sin and sensuality means defying God and His will—that will never end well.
