Sex advice?

Alright y'all I got a big question for you. How do I tell my boyfriend that I'd like to have sex, but not sound like I'm pressuring him?

We're both in college and both virgins (unless you count oral sex, which we don't). We've been together for almost three years now and I honestly believe that I'm ready to have penetrative sex with him. The only issue is that we previously talked about this last year and at the time I had mentioned waiting until getting engaged and he mentioned waiting until marriage. This has obviously changed on my end, but I'm not sure how to bring it up to him.

He's somewhat religious, so I think I know what his answer is going to be, but maybe I could be wrong? Also, I just feel like I'm hiding something from him, so I'd really like to bring this up.

But how do I do so without making it sound like I'm pressuring him if he's not ready? I know him and I know that if he's not ready he will feel bad about it and worry that I'm not satisfied with what we're doing now (which I most definitely am satisfied, but I just feel ready and I'd like to have sex with him if he also feels ready).

It just feels like a complicated situation, but we're getting an apartment together soon, so I feel like it will get even more complicated then. I could really use some help ladies! How do I tell him I'm ready without making it sound like I'm pressuring him?!
