First of all, is the Bible the words of God or the prophet.
Secondly, since when one has to use distasteful words to get their message across? The prophet Muhammad didn't feel the need to do so. He got his message across with wisdom as in the case of the man who liked visiting bars and having sex with lots of women. The prophet asked him how he would feel if that woman was his mother or daughter? The prophet said nothing else to him. The man commented after talking to the prophet, "I went in there liking women (meaning sex) more than anything else. After speaking with the prophet, it was the most detestable thing for me". That is the wisdom of Muhammad. Take the case of drinking. The passage stated that intoxicants was bad so shun it if you want to prosper. No shock treatment distasteful words. Yet the companions of Muhammad never touched it after that passage.
So God needing to report that the two whoring sisters like penises large like those of horses and ejaculations plentiful like that of horses is poor use of words by the God of the Bible.
