Is this SA?

I had a baby 3 weeks ago. My husband has been touching me, non-stop. Literally groping and dry humping me. Even when I say no, or stop he keeps doing it. I finally blew up today when i was laying down breastfeeding the baby. He came up, laid on me and started feeling me up. I screamed at him to stop touching me, he continued to do it. I was literally trying to push him off but he wouldn't. When he got up we got into a screaming match about how he refuses to respect my boundaries and the word NO. He goes on to say that he's "touched deprived" and that I'm emotionally and mentally abusing him. I said how is you holding me down to where I cannot move and you touching me sexually while I'm feeding our baby not sexual assault? He said because you're my wife and that is what you signed up for, i can touch you however and whenever i want to. I said that is ASSAULT and he said call it whatever you want but I can do what I want because you're my wife. And that I can't expect any different when I've deprived him for so long (3 weeks). I told him I DO NOT want to have sex, let alone have sex regularly before 6 weeks. He said well you have a mouth and a hand and that I can't punish him and manipulate him by withholding sexual acts just because I'm not in the mood. He said, "Sometime's we all have to do things that we don't want to do to please the people we love". And compared it to him getting me a sweet tea the other day from the store, even though when he got home he EXPECTED me to put out for it. I said that there is no way in hell that i would be sexual with him with the way he's been acting. And he said then he's just going to be mean to me until he gets it.
