Boyfriend and sex

Ok, so I have been dating this guy for almost a year and a half and we haven’t had sex yet, but I want to. I told him I was ready a couple months ago and he said ok. Obviously we still haven’t, but I’m also scared because I’m not on the pill so I don’t want to get pregnant. I also feel like he doesn’t want to and I want to know why but I don’t want to rush him in any way, I don’t know what to do
