Dom/sub advice

I asked my boyfriend if he could be more aggressive to me and talk to me aggressively. Although he isn’t really sure what I mean I can tell he has put in the effort to be more aggressive with me by telling me what to do and ect. I like when he takes control and tells me what to do and what not to do. Does anyone like to be told a certain thing? That can help give me and idea on how aggressive I want him to be to me? I like when we talk while having sex and when he makes me speak up or quite down. I really want him to talk more aggressively but I just don’t know what I am looking for him to say
