Boyfriend recently told me he wants to try oral?

We tried it once and he didn't like it. He got like two licks in and stopped. I really felt like it was me. I started freaking out. Just a few days ago, we were coming up with ways to spice things up a little and he mentioned that he wants to try it again. But. I don't want him to do it partially because I don't want him to feel obligated. But then again, I want him to do it because I deserve some too. 😩 I'm stuck. I don't know what I want. I also don't give him as much head because frankly, he burnt me out on it. At the time I thought I was proving something to him about how unfair it is, but now I'm not really sure. What would you guys do? He just sprang this up out of the blue and said he really wants to do it, not because he feels like he should in order to get head or anything.
