How to introduce vibrator to SO?

My SO and I’s sex life is great...for HIM. I’m his first and only sexual partner ever and I’m not overly experienced either. I’d like to introduce my vibrator into our sex life. I’ve only ever used my vibrator for masturbation though and I’m nervous because I’m scared he’ll think I look ridiculous using it or I’ll look cheesey having an orgasm (I’ve never had one except with masturbation, never in front of anyone else). I also don’t want him to feel as if he isn’t enough. I guess I’m self-conscious. Any advice?
