How was your libido before you guys had kids? I noticed you mentioned he is a great daddy? Could you possibly have physical damage.
Otherwise see a doctor, get exercise, and if he's a great daddy I'm sure he takes the kids sometimes so you get alone time?
I would get a medical check up. A marriage without sex is really a platonic friendship. And generally men or women in a relationship where libidos are that disparate will look somewhere else.
Plus no one likes an unresponsive partner, or at least no one with a healthy psyche.
What Sixstringer and Sammy said.
You may be stressed and tired from looking after 3 kids (I'm 25, I have two boys)
and perhaps you never really feel like sex because you're so busy with other commitments.
Also, it may very well be the fact you have a young child or a baby?? and so you are put off for that reason as Sammy said. I never wanted sex until my youngest turned about 2. Not sure if that was anything to do with what sammy said but it may well have been because I was breast feeding up to 9 mths old.
And picking up on what sixstringer said, it is worth keeping your realtionship healthy by trying to reignite that desire again. If he's a great guy, try to hold on to him. Work out together what can be done to make you 'want' him. Obviously it's easier said than done but it happened for me, so is worth a try.
Also, you could try pelvic floor exercises to improve sensations for during sex (the muscles may be loose after three births) Increasing the sensivity could help you enjoy sex a lot more and so your relationship could become more satisfying for you both.
Good Luck
Stress, worry, tiredness, these sorts of things can really affect your libido, typically women are more affected than men. Being stressed about not having sex is a great way to kill your libido, making you even more stressed - handy, huh? Being really busy all day looking after 3 kids can leave you too exhausted in the evening to be in the mood, too.
How old is the youngest kid? Many many women have little or no libido for many months following birth, it varies from woman to woman. I have a suspicion this may be the case particularly if you are breastfeeding - breastfeeding tells your body you have a young baby, and are not ready yet to start making another one, for the same reason many women don't ovulate for many months after birth if they are breastfeeding. (BTW, if you are breastfeeding, PLEASE don't stop just to get your libido back - your libido will re-appear eventually, but the health benefits to your baby of breastfeeding will last them forever).
Good luck, I hope things improve for you...
From my male point of view, a marriage without sex is headed for heartbreak hotel sooner or later. There's no doubt many details you did not include, but sex is in the top two reasons why men get married, so what does your husband say about this? Anything you can think of to get interested would be worth pursuing. With three kids, you must have been interested at some point, but maybe just for procreating purposes? If he is your "wonderful man" don't you have any interest in getting close to him on a regular basis? Are you filling your calendar with foolishness and overlooking priorities? Keep searching for answers.
Well I wish that was the case, but this has been a marriage long problem! I have been with this man for 8 years and married for 5. I wonder if it might be that he wants it more than I want to give? We have 3 children now and the problem is just getting worse!
may be u do sex a lot and don't wanna go again.....
keep some days gap....
