boyfriend wants me to take control in the bedroom

Ra

so lately my boyfriend of two years has been asking me to take control in the bedroom, and I don't know how to go about doing that. I have always been a super submissive person in the bedroom and submissive in the public eye as well but not as submissive if that makes sense. how do I go about taking control in the bedroom in a way we will both like. I guess another thing is I don't entirely know what it is he's wanting me to take control of either. cause I'll be giving him head or we will be making out and he'll tell me to do it just take control and I don't know what he means. because when I tell him I want him or I need him he tells me that he's mine. but even if I did know what it is he wants exactly I don't know how to go about taking control. so any advise would be appreciated.
