Once I got into my teenage years, it was eye-opening to realize how much “R-rated” material there is in the Bible.

Right! And saying Song of Solomon is R-rated would be too nice.

I’m no Biblical expert...but I do recall hearing on some radio program
(Focus On The Family??) that “Song of Solomon” was generally kept
behind locked doors (during Biblical times).

And it was only available to young Israelis when they were approaching “adult” status.
