Blowjobs v.s lickout

So me and my partner have been together for 3 years and I could probably count on two hands the amount of times he has gone down on me. Sometimes when we are lying cuddling he will push my head towards his crotch in order for me to start going down on him. What's with that ?? I really don't mind going down on him because he's my partner and I love him but it's a bit annoying and it's giving me a complex that he doesn't go down on me often at all. I've tried to explain to him a while back that it's giving me a complex but that didn't change much. Anyone got any advice on what I should do ?? Or experienced this themselves ??
