Since I dont know for sure how old you are, this could be a medical problem. Yes we women can have the same problems as men when it comes to sex. However, my guess is it is just that you have too much on your plate right now, and feel like sex is one more chore for you to fulfill. Find ways to make life more romantic for yourself. Buy hubby some sexy boxers--I have gotten mine some silky ones (great to touch) and other ones that I liked. Buy yourself some sexy undies--I am overweight as well, but they still have really cute things out there for us women, even Walmart. (though I dont really see the weight as much of an issue as the time part) Also plan times to be romantic and be creative during those times, like play games, like strip poker, or my favorite, strip trivial pursuit. Send the kids off some where for the night and have a romantic dinner and wear only your sexiest stuff, both of you. Candles create a wonderful atmosphere too. If you cant send the kids away for the night, then give everyone an earlier bed time and lock the bedroom door. But the most important thing to remember is to relax, when you worry about something like this, it makes it 100% worse. We went thru this, when we were trying to get pregnant for the second time and we both lost interest. Now, 3 yrs later, we are expecting #4 in March. So be playful, be creative, and be relaxed, planning time together does take the stress off and make sure it is known to both parties, that if it doesnt happen, it doesnt happen, and move on from there. It will come back, but it may take a few times. Good Luck!
