Did I do something wrong?

So I been suffering with PCOS for years now and my bf of 3 years never believed me because i dont show the “normal “ symptoms. So I finally found a dr who actually acknowledged that i have it and wrote it in my medical records. So I tell him that when I show him proof I want him to take me to dinner. Fast forward, he takes me to a play and dinner. After everything he drops me home and says that he wants to do a little something even though he has a headache. Im exhausted and have been up since 6am. Im not horny, nor am i thinking about sex. So I say ok so he doesnt get upset. We had sex and he said he wanted to eat me out. I have huge tities and his car is small, I feel unclean & again IM NOT HORNY i just wanna sleep. He gets some licks in and i get up cause im not feeling it and im uncomfortable. Today he tells me I shouldve found a way to make myself comfortable and that I dont show him that I want him. This is the same person who’s wishes I respected when he said he is doing a fast with his church so we cant have sex til November 12th. Like im confused.
