Not much to add here becos you've gotten great advice so far. And of course the key word is DESIRE. Genuine desire is even more important than frequency. You could try so very hard to up the frequency but if you're not really there your H will know and then you will have the sitch where you think "Hey, I'm trying real hard, how come you're still not satisfied" while he thinks nothing has really changed at all.
So how can you show him you desire him? Not by the frequency of sex but by the other little things. They won't take up too much time and it will make him feel really good.
- turn your good morning, good night or greet him at the door kisses to passionate kisses rather than just a peck. - write him sexy love mails (its okay if you don't follow through on that day itself, remember its desire and not so much the act itself that does it for the HDers) - lounge about the house in sexy, skimpy outfits he'll love and grope him when you have the chance. (not easy with kids around of course but try). He will love that you are dressing up just for him! I don't see any reason why one should dress up only when going out with friends etc, dressing up just for your H will make him feel really special. - touch, touch and more touch, rub his back, massage his feet, hands, head, body. No need to be sexual if you don't feel like it, it can be a relaxing massage that will send him off to dreamland happily. - have a shower together. Hey it saves time and you can chat about your day. (Don't worry, it need not translate to sex every time. Just being playful and showing him that you DESIRE him is enough.) - play with his hair, look into his eyes when you speak, trace his lips, and give him your full attention - and on those days that you really, really don't feel like it, take a rain check. Mercy sex makes the HD feel really bad. It reinforces their thinking that the LD spouse really has no desire for them.
