Need Help!

So my boyfriend and I were doing things. He asked if he can stick it in but, I said no if he didn’t have a condom on. Then he hit with “I don’t like condoms, I feel like it will choke my dick”. I told him that as long as he wears the right size everything will be fine. He still said “no”. Like I know guys don’t like it but still wear it. I told him I’m not having sex with him without a condom on. Then he asked if that meant we were never having sex . I told him yes as long as he has a condom on. He got a bit upset & we didn’t talk about it anymore. I don’t know what to do. I’m not willing to have sex without him having a condom on, I know I have to talk to him but i don’t know how.

ps. He is clean I know that for sure, we both got tested and btw im his second girlfriend if means something.
