A Vanilla Sex Life??

My husband and I have been together for 6 years. we’re 22 and 24, and I want to try and spice up our sex life, I’ve mentioned things like a cock ring, or any toys and he’s like “noooo” “chill” I also joke that I want him to like stuff my panties in my mouth and he just says chill. The most he does is spank me hard and choke me lol. We get a little more crazy when drinking that’s it. Lol. How can I spice my sex up and make him comfortable??
