Pressured to do Anal

So me and my boyfriend have been together for a little bit now. Well the topic of anal has come up... I'm not for it at all but he really wants me to try it. I like him and want to satisfy him but at the same time it's just kinda off limits for me. And I'm no way has he forced me to do anything ect. He thinks I'm "closed minded" because I don't wanna try it, but I'm open to pretty much anything else. Maybe I can try to spice things up anther way? Any advice?
