How often do you give your partner head?

I’ve never been comfortable giving BJs... I haven’t really done it that much at all because I gag big time and it’s just really uncomfortable. My now husband (been together 10 yrs) maybe have given him max 5 actually BJs... we have done 69 and other things but I’ve given 5 BJs where I solely focused on only getting him off. Not just sucking on his dick for a min or so just to turn him on. He has never come from me giving him head... and says he doesn’t care at all. We just always move on to other things and have amazing sex.

My question is... should I make more of an effort, maybe he is missing out? Maybe I’m doing something wrong, I gag so badly then I’m like crying and he notices and says it’s totally okay and we just move on then.
