Porneia means ‘to sell oneself’ and often in the Bible as in classical Greek has a clearly non-sexual context. No sex is possible, for example, in Hebrews 12:16, where Esau is a pornos for eating a bowl of soup.
Bible scholars often note porneia is an offense related to idolatry, given a sexual character because God and Israel are metaphorically married. I gather resources about porneia here. Note Roy E. Ciampa and Brian S. Rosner in a recent commentary on 1 Corinthians: “most of the references to prostitution in Paul’s Bible are figurative, referring to Israel’s unfaithfulness to the Lord and worship of other gods, which also help explain Paul’s treatment of porneia in terms of unfaithfulness to God.”
Since you’ve asserted porneia is always a reference to humans being sexual, I now have to decide whether you are ignorant, or lying.
