First Boyfriend

I’m two months into my first real relationship with possibly the nicest guy ever. He’s fingered me and we’ve had sex (for my first time which he knew) but I still haven’t given him a blow job or even touched him cuz I’m too nervous! He’s never asked for anything but I feel like he is just trying to be nice and not push me. I’m also not sure how long it’ll be before I’m comfortable with blow jobs. How should I bring this up to him without being awkward? I’m too shy when it comes to topics like this 🙈
