Spice up our sex life

My husband and I want to spice up our sex life. A few months ago he bought a cock ring and a bullet vibrator for us; however, I don’t like either because I can’t feel the cock ring and vibration on my clit just makes it numb. He recently started trying to eat me out for foreplay, but he just goes straight for my clit which doesn’t feel good. I’ve tried explaining why the vibration and direct stimulation of my clit doesn’t feel good but he keeps trying it. I need more warm up time than he does. Any suggestions for us to spice up our sex life? We need help.
