Blowjobs

So my boyfriend and I are having some differences in I suppose what we want. A little backstory, I am the one who took his virginity but before me he has received a lot of blow jobs and enjoyed them. I on the other hand have never given a blow job before and honestly the thought of it is terrifying. In my first relationship my boyfriend had never had one and we didn't get super intimate and in my last relationship that just wasn't something my boyfriend wanted. I'm more than insecure about screwing it up or it tasting bad or doing something along the line of choking because that would be just my luck. Am I crazy for being 22 and never giving a blow job? Does anyone know of a compromise? I want him to get what he wants but I'm just not sure how to get past my issues.
