My bf constantly gropes and touches me in private areas. I hate it, and he knows it, but he still does it. ?

I can't walk by him w/out him slapping my . He grabs my , and asks for milk....I mean isn't that sick !!! After I take a shower, he asks to see my naked body..so now I take my shower when he's asleep. He acts as if I'm his property since we are dating. I get SO grossed out by him, that it's becoming very hard to kiss him. He told me yesterday that there is something WRONG with me because I don't want to kiss him. As if I am abnormal. I stay at his house sometimes because we live in separate towns, and I'm not really worried about him raping me, but he has been showing a more violent side lately. He threw an ottoman across the room, and almost killed one of our kittens. He has thrown others things as well, but hasn't broke anything. How do I get through his thick skull to stop doing things I don't like him doing.
