The truth is we don’t subscribe to the specifics of Paul’s sexual ethic today—at all. Paul has some good stuff to say about marriage. In 1 Corinthians 7 he talks about how we use our bodies and sexuality mutually. Really progressive stuff in the first century.

We often hear Jesus' teachings on sexuality and assume he was against desire but that approach fragments our humanity and sets up unreasonable expectations. A better way to understand Jesus' teaching is to hear his caution not against sexual desire but against the dehumanizing of another human being into an object to be used.

The word "homosexual" doesn't enter the conversation until the 19th century in Germany and isn't used regularly until the 20th century in English. Before that, homosexuality wasn't considered part of someone's identity simply, a thing one might do. Which is why it doesn't enter the translations until around that time. Instead "boy molester" was probably considered a more pressing "sin" culturally to fit the term arsenekotais which is literally "man-bed".
