In relationships lasting a year or longer, one-third of women lose interest in sex for at least three months, as opposed to 15% of men, University College London research finds. For 11,500 Brits surveyed, pregnancy, health problems, and age are factors. But women’s sex drive is more sensitive to relationship quality and emotional connection. So if there’s strain, mistrust, or even boredom, you may still be into it though she may not. Fortunately, communication can preserve the spark. Talk about how you’re both feeling, and consider a counselor to get (and keep) a dialogue going.
