As hard as it can be to find time or energy for sex, Amy says it's an effort worth making. "We have to make sex a true investment in the marriage," she says. "A good marriage is the backbone of a healthy family."

Date nights and moments of intimacy send important messages to both your husband and your children about your priorities, Amy says. "One husband said [to me]: 'I used to be first, and now I'm pulling up the rear. I'm behind the pet rabbit,'" she says. "Our kids are watching us. So when you go out on that date, you have to sit your kids down and say, 'This is important for our family.'"
