Condoms

My boyfriend and I have been together for almost 6 years, and iv just recently stopped my birth control and now he refuses to wear condoms. I tell him we won't have sex unless he wears them because it makes me to stressed out and sex uncomfortable for me because I don't want to get pregnant. He then tells me that I don't "put out" anymore because I don't initiate sex, but it's just not enjoyable for me when I think this is the time I could get pregnant because he won't wear a condom..... Has anyone else been through something similar? What did you do?
