Devote Yourselves to Prayer

Today I was listening to part of 1 Corinthians 7 and heard this:

3 The husband must fulfill his duty to his wife, and likewise also the wife to her husband. 4 The wife does not have authority over her own body, but the husband does; and likewise also the husband does not have authority over his own body, but the wife does. 5 Stop depriving one another, except by agreement for a time, so that you may devote yourselves to prayer, and come together again so that Satan will not tempt you because of your lack of self-control.

What struck me was that Paul included this exception, it the midst of giving this advice regarding sex in marriage, for a time of devotion to prayer...a time when a couple would be so devoted to prayer that there isn't even time to spare for a bit of marital intimacy. Do you have that kind of prayer life? I don't. Makes me realize that I might be missing something.
