The sexual sins of male and female prostitution that Hosea describes here are listed because they are the results of the spiritual prostitution that Israel and Judah had committed. It is not so much that God is condemning his people for their sexual sins, but that he is condemning them with the sexual sins. The apostles Paul made the same point in Romans. When a society rebels spiritually, one of the first things to go is sexual purity.
LORD, restore us to a right relationship with you, and restore our relationships with each other.
Hosea 4-5
