Who has control

so me and my boyfriend we talked one night and i asked him who has control when having sex. we both said him. We went to go see each other and i’m riding him and he has control. but after the day was done, he told me that he wanted me to speak up & take some type of control. i’m a submissive type & i don’t want start having some type of control & start being more open-minded when we do it. what should i do? listen to him & have things change or just have let him take control ?
