Are you experiencing DINS? That's Double Income No Sex. According to the April issue of Health magazine, researchers say it's natural for libidos to "cool off during the career- and family-building years."

Jackie Singer, an Irvine psychotherapist, says she has counseled a number of weary couples who work long hours during the week, spend weekends running around with their kids and seldom find time for each other. She has her own acronym for them: DILS (Double Income, Little Sex) or DINS (Double Income, No Sex).
