Vanilla SO

My SO is very vanilla, unlike me. Anytime he sees something having to do with even mild bdsm he gets very uncomfortable and awkward. He knew that I had toys when we got together, almost 4 years ago. I really want to use a vibrator during sex, because I've been having trouble squirting since having a baby. I feel that it would make sex even more amazing for both of us. I have no idea how to bring up the idea without making him uncomfortable or feel like he isnt enough/ Good enough.
