Sex toys in a relationship?

So I've been interested in incorporating sex toys into my relationship but I'm not sure how to bring this up to my bf. He kind of shut down the idea of us trying to use a vibrator as foreplay when I brought it up because he didn't like the idea of a vibrator pleasing me in that way and he wanted to be the one to satisfy me in that way, but I still want to try that kind of stuff out...any advice?
