I was reminded of it recently by a column by Dennis Prager (http://townhall.com/columnists/DennisPrager/2008/12/23/when_a_woman_isnt_in_the_mood_part_i)
I think I'm going to distribute it to all the young couples in our church. I'll wait for Part 2 to come out, and perhaps distribute both. From a New Testament perspective, though, I'll add a couple of thoughts to Mr. Prager's article. (He's Jewish.)
The primary point of his column is that men take s*x (word altered to keep from being flagged as p*rn or found on searches by p*rv*rts) as "I love you" and the denial of same as "I don't love you," and there is nothing more powerful for good or bad in marriage.
I'll add two thoughts to it, though: First, a reminder that the apostle Paul wrote to the Corinthians that we have not the right to deprive our spouses, and secondly, that God never allows us to predicate obedience to His ways on someone else's. In other words, nothing my husband does eradicates my obligation to obey God's revealed will regarding my behavior as a wife.
