The point is that the term “one-woman man” was a “buzz phrase” that meant someone who was faithful to their one spouse (assuming they had one). This is why it can apply to both men and women when found on a tombstone in Ephesus.

Pagan women were expected to be faithful, but pagan men were not.

The reverse phrase “one-man woman” is also in 1 Tim in discussing widows. We know women could not be polygamous in any Roman controlled area.
