Hello Chiquita,
Firstly - Hello! Welcome to the site.
Has he been open with you about his expectations? Has he outlined exactly what he expects of you in and out of the bedroom? Once he defines these parameters (and at first, there may be very few due to his inexperience), and he sees how you thrive under those conditions, it may encourage him to expand his dominance to other areas of your lives.
For instance, you mentioned that there is nearly no control outside of the bedroom. Are you hoping to change that? A simple expectation from him like "dinner on the table by X time each night" can turn into a very lovely display of going above and beyond to serve him by cooking his favorite meals, surprising him by trying new dishes, getting a recipe from his mom that he liked as a kid, a table setting with candles and flowers, etc.
Obviously I have no idea if you have that kind of time in your evenings, but that principle - showing him that you will go that extra mile every time no matter the expectation he has - will show him how happy it makes you to submit to him, even in the everyday mundane areas of life. This may be the key to expanding his comfort in dominating you outside of the bedroom.
Good luck to you, and no matter what you decide to do, please do keep us posted on how it all goes!
