I know how you feel. I’ve been in that same boat, especially when our kids were small; and many other women share the same sentiments so you are not alone. There are a number of different factors that can screw with your libido. One of the most likely culprits is stress. You’ve got kids to take care of, a house to maintain, and a hundred and one things on your to-do list. You didn’t mention working outside the home but many women do and that only adds to the overload. It’s hard to switch straight from feeling like a busy machine into a sex kitten at a moment’s notice.
Make a real effort to work date night into your schedule at least twice a month, even if that only means sending the kids to the grandparents for a few hours or overnight so you and your hubby can share some alone time to just relax and be together. Take time to learn to talk to each other again, cuddle up and watch a movie together, and rediscover the joy of kissing. You might be right back in the whirlwind the next day, but those few hours of closeness can make life so much more pleasant.
