Weirdly the Bible in original verse only condemns Adultery. Which is sex with others if you are married. There is a few verses about the immoral but doesn't define it. Occasionally mentioning lying about being a virgin but that is just decietfulness. Then you get to the new testament when Paul goes all purity culture on everyone. Jesus is all like sex workers are cool and it is fine. But Paul is like sancity of marriage and how sex within marriage is the most pure and beautiful thing using metaphors about how it is llike God and the church. Paul is really a questionable fellow
