It’s a topic that used to be taboo in church—a topic that made church ladies blush and teenagers giggle. If it wasn’t totally off-limits in a church, it was handled with great care and (usually clunky) attempts at subtlety. But not so these days. Over the last few years, sex has not only become accepted as a sermon topic; it’s become almost requisite. If you’re a pastor and you haven’t done a sex series or at least a mildly scandalous sermon on Song of Solomon, you’re behind the times.
