Two men who know a lot about the male psyche -- Dennis Prager and Shmuley Boteach -- take their turn at this perplexing question. They approach it from two different and opposing angles, making for a very spirited debate. As the sparks fly, a lot of wisdom, of great benefit to both sexes, also emerges.
