Guys, should I be worried?

Okay so me and my boyfriend have been together almost a year and love each other. But he occassionally jokes about me being a slut/whore etc., as I'm quite open to things in the bedroom and a little bit naughty.. Other than that I'm a nice person and loyal etc. I just don't know whether I should be worried about him saying these things, I might be open to stuff when it comes to sex, and have a high libido but does it sound like thats making him think different of me? He says he loves it about me but I don't want the way I am in the bedroom to affect how he sees me out of the bedroom. What do you guys think? How would you react to a situation like this?
