How to take control in bedroom?

Pip • Baby dust to all you ladies ❤️
Me and my partner have been together a year and he always does all the work. Every time I've tried to take control or Im the one doing the work, he stops me and then he takes over. I don't understand why? How can I get some control in the bedroom! Someone just told me he'll get bored of me this way, so need some tips!
