First off.... I agree that it does not belong in Sunday school class for the most part.

Second, when I was in Sunday school I cannot imagine any of my teachers bringing it up. To them SEX was a four letter word. Something done behind multiple closed doors, in the dark, silently, and never EVER admitted to -with the assumption that all the kids running around just spontaneously came to be.
Now things may have changed since the early 80's but my fear of such a topic in SS is that the teachers would be too "prudish" with the "sex is for procreation only" doctrine being taught.
