Sad about big boobs and butt, bc I’m not like that

I feel so sad bc my husband of 5 years, LOVES women with huge boobs and big butts, but here I’m skinny, small tits and butt, he likes to watch porn, sometimes I watch with him, but he always in our sex is referring to those women, one day I told him if can lay over me (missionary) and his answer was that the day that I will have big boobs he will do it. He never kiss me or my body and we do it we the lights off. Many times make me feel like I’m worthless even without a word coming out of his mouth, is how I feel 😭 and any time that we have an argument he always blame me even for our poor sex life, bc without porn he doesn’t work bc if I’m not in the mood to watch porn with him, he gets upset. I look my life before him and I remembered the good times I had and how great I felt about my body, but now idk 😐, please any advise 😶
