Please please please I really need some opinions

My boyfriend and I are both 16 and we have been together for 7 months. We are sexually active, he where's a condom and always pulls out but I am not on the pill. Ever since we started having sex I get stressed and completely freak my self out that I could be pregnant. He always reassures me that I'm fine and to stop worrying. He's told me that I am the one he wants to marry and spend the rest of his life with. I confronted him last night about it and told him how I was feeling and I asked him what he'd say if we stopped having sex until marriage. He wasn't fully on board with it as sex connects us on that deeper level and he said that it would effect how intimate our relationship is. But he said he hates seeing me unhappy and stressing about something that we both should enjoy. He sent me this text after. What should I do?
