Orgasms

So my boyfriend and I have great sex and he always orgasms but I don't. I can't do it vaginally. So he use to be able to rub me and boom, orgasm but I used a tooth brush for masturbation and ever since then he can't get me to orgasm but I can do it just fine without it. I tell him where how and everything else to it but he just can't do it and we both get frustrated. He won't use anything but his hands to rub me. Help
