Just read your post to Nopkins. As far as not letting sex get boring or routine, that would be my next area to address, although it's ridiculous to consider quality when there isn't any quantity. How can one improve something that you don't practice. If "practice makes perfect" then "neglect makes atrophy".
Anyway, I wanted to make some points for you. First off, have you bought that aphrodisiac book I suggested for you? No? Well, get your butt off the couch and get it. (trying out my Corri style advice ) Seriously, most of the sex help books out there focus on making sex exciting and fresh. You have the battle mostly won already by just being interested in making it better.
I think a lot of boredom can be avoided by simply nurturing a SPF 45 desire, that is, if you are both really hot and horny and follow the course of nature, you will be gettin' it on in fun places and in fun ways. Don't be afraid of taking chances, trying things that you're not sure if he'll be shocked by. My guess is he will be shocked with the biggest horny grin you could imagine. Remember the smile you put on his face when you followed my "bj surprise" advice
If the 90's were about finding your inner child, then the 00's + are about finding your inner, well, slut (this includes LD guys, hope I'm not offending too many here, but let's be frank). Why not? What have you got to lose by going after your sexiness like a hungry tiger? You have only to gain a husband that will adore you and hardly wait to be with you. Don't be shy. Do the unexpected, surprise him, get creative.
Ok some specific ideas; remember that I don't know your husband so I'm going from my perspective, you'll have to adjust for his desire level. I'll try to keep it under X rated.
If you do have sex in the bedroom, then go for some different positions: front/back: standing, sitting, kneeling, crawling, upside down, sideways, "the corkscrew", blindfold & tease, "choo-choo train", "the flamingo", whatever. Get silly. Tease each other with a glass of wine or a squeeze bottle of your favorite honey or chocolate. Flirt and tease, that will drive him wild. Lingerie, whipcream, candles, music. Tear the blankets off bed and throw him down. He won't put up a fight. Take the reins occasionally, give him a break. I could go on...
Now, out of the room: kitchen floor (mopped), kitchen table (tell him what's for dessert! ), stairs, living room coffee table, sofa, easy chair, laundry room, out on the deck--Yes! Take some risks, be sneaky.
Out of the house: In the woods(hiking is good for you! Sex in the woods is even better for you, just watch out for poison ivy and nettles ), touch him under the table in a dark restaurant, skinny dipping at the lake (before winter hits), in the car on an isolated road, in short, look for the opportunity.
