bf bad at sex?

Been with my bf for 2 years and sex hasn't been the best. His the only guy I've ever had sex with and I have NEVER orgasmed naturally with him. For the past 2 years and whole sex life I've used a vibrator on my clit to cum during sex. It is only now that I'm getting tired and bored and frustrated from this. I switch positions up and try new things and still can't seem to find "the spot". My boyfriend tries to do his best which I appreciate. When he fucks me I feel like his body is moving more than his penis if that makes sense? I've told him how i feel but nothing seems to change. What can I do? I don't want a boring sex life for the rest of my life. I'm sick and tired of cumming with a vibrator, really my vibrator is fucking me and not my boyfriend! 😤
