My bf doesn’t eat me out

I always pleasure him and I give him head for long extended amounts of time over and over again sometimes for 20 minutes + yet he won’t eat me out or try to pleasure me back by going down on me. I have spoken to him about it before, he licked it twice and then stopped. He wasn’t ever even went down on me properly. It’s getting quite annoying now because o know the only way I can climax/ orgasm is from being eaten out from my past experiences and I have spoken to him two licks and stopping isn’t him doing anything.

Feel frustrated because I always try my best to pleasure him.

I do make sure everything down there is well and good. Before we do things
