Sex toy?

My husband thinks using sex toys, in my case a vibrator, is in some way cheating. As if you don’t get sexual pleasure from your partner but for me it’s just one way I’m able to get in touch with my body. I’d don’t know how to talk to him about it because he just seems so against it that he doesn’t listen. I’ve tried asking if he’d use it on me during sex and he got mad at me. I don’t have one for these reason but wouldn’t mind having one because some days are lonely and some days you can tell he’s just not very interested.
