Lack of bedroom intimacy

Okay ladies, I am asking your advice. I have been married for almost a year. Seems much longer than that and I wouldn't say it's been a happy first year, but it is what it is right? Anyways, my libido has always been extremely high, but here lately I have no drive at all. I don't enjoy any form of physical contact with my husband, basically it's a chore which I have no desire to do, kinda like dusting or laundry. You know, have to do it because you know it's a necessity, but you dread it. This has been going on for several months. Honestly, like once a month if that is all I can stand. I guess it could have something to do with an argument we had around 3 months ago, when I asked him why he doesn't slow down and take time for himself and me. His response was, "The only thing that would make me slow down is something you don't want." Won't lie, at first I had no idea what he was talking about. He proceeded, "A kid." My response was, " I told you before we got married I didn't want kids and you said it was fine." He did agree with me but stated, " I figured you would have changed your mind by now." I was livid by this point, mostly because I had told him for years before we got married that I had no desire to have children. He always was like that's fine, you came before a child anyway, etc. Now he has expected me to change my mind. Anyways, I gave the only response I could think of which was, " I told you before we got married I didn't want kids, this includes baby all the way through young adulthood. I don't want to adopt, I don't want to get pregnant, or have kids." He snapped back, " Well if you don't want kids you need to get back on birth control or have a doctor fix you because I am tired of having to pull out." ( I was hurt to my core because all my life I have had complications/severe side effects when I took birth control, and I have asked my doctor on several occasions to make me sterile/unable to have children and I always get the response "You're too young you may change your mind later in life" I have asked since I was 16 to be made sterile and my husband knows this , but no doctor here will perform the procedure. ) I simply said, "Or we can just not have sex," That was the end of the conversation. Since then I have had no desire to do anything with him, but I still do on occasion because I know that sex is important to a marriage, however I don't enjoy it. Any advice is appreciated.
