How do i tell my bf i want him to be more dominant

Shitty thing is his work schedule, we havent had sex in a month (dying over here) not only that but how do i tell him without making him think im unsatisified that id like him to just rip my clothes off and be a little more rough. I feel like hes so shy in bed even after 9 years of being together. I want to spice it up. Helllllp !
