Google Dr. Laura Berman, a noted and respected sex therapist. She has a great daily e-newsletter called "The Passion Files." It gives great down-to-earth ideas about all sorts of sexual issues. Everything I've tried from her e-newsletter has worked brilliantly.
Additionally, from personal experience, I know that when my kids were small, having the energy to devote to sex was nearly impossible to find. It got marginally better when my husband picked up more of the household responsibilities (we both worked full time). Now that my boys are teens, and I can sleep my normal hours, my libido is nearly back to where it was before babies (too bad my husband's isn't <wink>)! Perhaps your husband could pick up one or two evening responsibilities so you can have some down time to recharge your batteries so you can share some energy with him?
I know it seems depressing to think you have to wait until your kids are teens for the rest you need to feel sexual again. That was just my experience. If I knew 10-15 years ago, what I know now (thanks to Dr. Laura and others), well, let's just say I'd do things differently to keep the bedroom fires burning!
Good luck!
PS: I read this on one of my various news sites on the health page. This article said that couples who take the time to tongue kiss at least once each day feel more connected and intimate with their partner. On a whim, I emailed this article to my husband and every day since then, I've gotten at least one GREAT kiss a day, which has definitely revved my engines up more than usual. Give it a try...it may work for you, too!
