Is it okay not to like oral sex?

I’ve never performed oral sex, and yesterday my boyfriend went down on me, it’s the second time, I never asked him and he really enjoyed it. and i wanted to do the same to him and so when i did “sucked” him, I didn’t enjoy it at all, i hated every second of it and I couldn’t back off so i just went with it, but i felt like imma throw up

and I wish i’ll never do it again, is that bad?

It’s really different from what i see on porn, it’s looks idk? Sexy and enjoyable. Idk i feel bad i wish I enjoyed it.
