How to get bf to go down on you?

My new boyfriend never goes down on me I'm a clean person I don't understand why he doesn't my ex couldn't get enough of it he would alway want to go down on me and my new bf said he doesn't get into. He's a selfish lover there isn't any foreplay it's just in for 5 mins and done? Is it bad if this is a deal breaker for me? I know sex shouldn't be the foundation of a relationship but it's important right?
