The argument to "wait until marriage" puts sex so high on a pedestal that love and exploration -- what sex is truly about -- are lost to fear and uncertainty. It makes any kind of sex before marriage experience (good, or bad, or ugly) look like a failure when, in reality, those experiences can teach us a lot about ourselves, our wants and our desires.
Great sex happens when both parties are into it, and telling women that they need to offer more sex in order for their husbands to maintain a fighting weight and sunny disposition seems like a twisted way to incentivize the act. So please, Wall Street Journal, stop discussing sex as though it's a duty instead of a pleasure. That isn't good for anyone.
