Bf told me him and his ex did anal

My boyfriend of only a year asked to have anal and I said no I never had it and doesn't turn me on. He said he is really into it and he use to do it all the time with his ex. I was pisses he even mentioned that like I care about what sex him and his ex done. I feel he only said it for me to do it to please him like his ex I told him if I'm bot good enough he could go back to her then he said it has nothing to do with her he wants it with me he doesn't get why I'm mad about him telling me. So annoying
