How can I get my boyfriend to be adventurous in the bedroom?

My boyfriend is amazing and we have great sex, but sometimes I'd love it if he was a little more adventurous. He kinda just wants to do whatever will get the job done when it comes to sex. But I'm more adventurous and would love to try something new. Like video taping us or having him be a little rough with me. How do I have my boyfriend take a little more control in the bedroom?
