I was similar to you. No sex drive and my husband suffered at first. What we did was snuggle, watch a movie, and make out. I forgot how heavy kissing can effect you. Sometimes, instead of having sex, I got out some lotion and just gave him the pleasure. He enjoyed having it all focused on him and the pressure was off me. Personally, I believe that I needed to make an effort. I would not like the shoe on the other foot. There is a delicate line between both of our needs. Sometimes I made the effort and sometimes not. I tried to keep a resonalbe balance for his sake. Feelings come and go and some of the best advice I got about marriage is that "feelings come and go, if you act like you feel it, the feelings will re-emerge". Basically, if you do other intimate things, slow dance naked, body message- both naked, hand jobs,etc...the feeling that those things stir will emerge and if they don't, he can still get some release for his building tension in a positive, loving way.
Good luck and best wishes!
PS - If he complains when you make the effort, I would tell him that you are making a special effort on his behalf because you love and appreciate him, but he needs to understand you need time and to enjoy what you are able to give at the time.
