I don't know your situation either, but hope you won't mind my adding one to the above ... If you have 2 (or more) children, it may be in part that she is so busy being a mom and caretaker that she doesn't have time or energy to be all that sexual. Do one chore a day that she would usually do ... don't make a big deal about it, just do it and move on, allow her that little bit of free time ... time where she'll be thinking ... "man, I've got a wonderful man who does little things around the place to help me out" .... pretty soon, she'll be thinking of snuggling up to you while you do a load of dishes, or reaching out to touch you as you move past her with the vacuum.... at least that's what would do it for me if I were in a similar situation.
