Want more in my relationship

Hi no debate tonight I’m afraid. Basically I’m in a relationship with someone and I want more from it I have tried to speed things up but he won’t have it he gets overwhelmed. We both have autism and I’m in my 30s he in his 40s but it works well for us. I have tried hinting we go out for a meal no luck I’ve tried dressing up nice for him he likes it but that’s about it. We kiss on the cheek and hold hands and snuggle up together watch films together eat pizza or Chinese which is nice but I want more. I think this issue is I have been in relationships before but they ended badly and my boyfriend hasn’t been in a relationship at all. We have spoken and we are growing closer he just says he still getting used to having a woman in his life. How can I help him get used to being in a relationship? I have tried and tried different techniques even tried telling him straight I want more but that just caused an overload and he just sent me a very abrupt message back and blocked my number for the day but that has been sorted now and we are arguing less he just tells me now to slow down and to relax. I do want us to work out and I know deep down things will work out as we both are trying to understand one another.
